Features

Open-E Data Storage Server is an all-in-one IP-Storage OS offering NAS and iSCSI

(target and initiator) functionality in a single application with excellent enhanced management and superior reliability for organizations of all sizes.

2.1 What is Open-E Data Storage Server

NAS ( Network Attached Storage ) solutions are defined as storage systems that are directly hooked up to a network infrastructure. Also, they operate independently and do not have to be connected to a server via a controller or host adapter. The term

“storage” here generally refers to all systems that either provide data storage or actually store or organize data. Currently, data storage is the most common and most widespread type of NAS systems.

NAS solutions are based on a separate operating system (and often also on special hardware), which operates independently from the servers on a network. Typically, this operating system is software that is optimized for providing data (file server).

NAS solutions allow users to add additional storage to existing networks quickly, easily, and cost-efficiently. iSCSI ( internet SCSI ) is a protocol that encapsulates SCSI (Small Computer System

Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. By using iSCSI, you can supply high performance SANs (Storage Area Networks) using standard IP networks like LAN,

MAN, WAN or the Internet. iSCSI solutions are based on a separate operating system and often also on special hardware. Typically, this operating system allows operating iSCSI technology. iSCSI solutions allow users to add additional disk devices to existing networks quickly, easily, and cost-efficiently. iSCSI has a client-server architecture. Clients of an iSCSI interface are called

"initiators". Initiators issue iSCSI "commands" to request services from components, logical units, of a server known as a "target" The "device server" on the logical unit accepts iSCSI commands and processes them.

Open-E Data Storage Server provides a fast, reliable, and scalable platform for IP-

Storage and combines the power of NAS & iSCSI in a single operating system. No matter if you need file sharing, storage consolidation, backup and recovery, virtualization or replication, Open-E Data Storage Server offers excellent price-toperformance ratio, enhanced manageability, and increased productivity.

The flexible design of Open-E Data Storage Server enables organizations of all sizes to create effective NAS and/or IP-SAN/iSCSI solutions that can adapt to and meet the simplest or most complex storage needs.

7

Open-E Data Storage Server is built on the proven Open-E NAS-XSR and Open-E iSCSI family with all of its superior security, stability and management advantages, and is Open-E’s fourth generation of IP-storage software.

Open-E Data Storage Server adds new back-up capabilities, simplified setup and storage management, extensibility, and is specially tuned to provide optimal datathroughput and data protection for centralized storage. Open-E DSS increases iSCSI target efficiency by supporting multiple iSCSI initiators on different volumes, without sacrificing NAS performance.

2.2 DSS functionality

Open-E NAS Data Storage Server is one of the easiest ways of implementing an NAS server and/or iSCSI technology in your network. Through its simple architecture – in principle, it is a flash memory with a USB 2.0/1.1 port and Open-E Data Storage

Server as its operating system – Open-E Data Storage Server can be used with all x86

PCs containing USB ports, an IDE controller and an additional SATA Controller on their mainboard or hardware controller.

To begin working with Open-E Data Storage Server, all you need to do is assign an IP address to the NAS server and/or iSCSI target – either automatically through an existing DHCP server or by assigning it manually. All other settings are handled via a web front-end which can be easily accessed through the IP address of Open-E Data

Storage Server using the encrypted https protocol.

Open-E Data Storage Server allows users to create so-called shares (i.e., resources within a network that numerous users or user groups have certain access to). The access rights to the shares are controlled through the user and user group settings.

Open-E Data Storage Server allows users of client stations to delegate disk devices and aggregation and form iSCSI Targets and their local mounting from any site in the network.

2.3 Why Open-E Data Storage Server?

Often, storage in network environments is expanded the following way: file servers have to be shut down in order to install additional drives. Next they need to be reconfigured. This tedious task often includes copying data manually onto larger drives, consuming a lot of time and money.

With Open-E Data Storage Server, you can

• add storage to your existing network quickly, easily, and most important, costefficiently.

• consolidated storage and backups for multiple servers.

• improve data availability and efficiency .

• lower costs by centralizing storage management.

• simplify the installation and on-going management of a SAN by using iSCSI versus using Fibre Channel.

8

Expensive hardware is, therefore, no longer necessary. Take any computer – a new rack server or an old desktop PC with USB ports 2.0/1.1– and exchange the system drive for the Open-E Data Storage Server USB flash module. To store data, Open-E

Data Storage Server uses IDE (ATA) and SATA hard drives, connected to ports on your mainboard or hardware RAID controller.

Additionally Data Storage Server supports software RAID, so you can create software

RAID over single hard drives or over existing hardware RAIDs.

For example, you can create a software mirror over two hardware RAID5s for very high reliability.

Within a few minutes, you will have up to several hundred gigabytes available on your network – without much effort and any downtime.

2.4 RAID types

This manual is not intended to replace your RAID controller manual. But we want to provide you with an overview of common RAID types so that you can make an informed decision on which type to choose. Depending on whom you ask, RAID means either Redundant Array of Independent Disks or Redundant Array of

Inexpensive Disks. Both are correct. In essence, you combine the capacity, speed and security of several disks into one.

RAID 0 forms one large hard disk by concatenating stripes from each member drive.

Stripe size is configurable roughly between 64 KB and 1 MB. The result is a lightningfast RAID, but with no added security. One failing drive may ruin the entire RAID.

RAID 1 mirrors hard drives. By writing identical data onto more than one drive, security is enhanced. A completely defective drive does not cause any loss of data.

The drawback is reduced performance and capacity.

RAID 5 combines data striping from RAID 0 with parity checking, therefore combining speed and improved security. The loss of one drive is tolerable.

RAID 6 extends RAID 5 by adding an additional parity block, thus it uses block-level striping with two parity blocks distributed across all member disks. It was not one of the original RAID levels. The user capacity of a RAID 6 array is N-2, where N is the total number of drives in the array. RAID 6 does not have a performance penalty on read operations, but it does have a performance penalty on write operations due to the overhead associated with the additional parity calculations.

RAID 10 is a combination of RAID 1 and 0, hence the name. Data is written in a striped and mirrored configuration, providing high performance and robust security.

Hardware installation

3.1 Getting ready

Switch off the computer, remove the power supply, and open the PC chassis. In tower systems, the side parts often can be removed individually (you just need to remove a few screws on the backside of the chassis . Many machines have U- or O-shaped covers that have to be pulled off (either towards the front or the back). Should you need any assistance, please contact your dealer.

Now locate the USB connectors on your motherboard:

10

Every motherboard has at least two such ports. To install Open-E Data Storage

Server, you have to use an existing one

3.2 Installing Open-E Data Storage Server

If necessary, remove the flat band cable that connects your hard drive with the controller. Open-E Data Storage Server should now be carefully inserted into the USB the connector. As USB ports can have a notch on one side, you can only insert the connector at the preset position (see photo).

That should conclude the installation! Before replacing the chassis do not forget to connect your hard drives to the IDE connector, SATA connector or to the SATA port on the RAID controller. If you have a CD or DVD drive, you can remove it, as Open-E Data

Storage Server does not support optical drives, but if you want to make an ISO update it is not necessary to remove the CD drives (see 5.2.3.8).

Configuration

4.1 The basic configuration of the Data Storage Server computer

Connect your keyboard and a monitor to the Data Storage Server computer. You will only need those devices for basic configuration or extended maintenance configuration.

You may have to change the function “Halt On: All Errors” in your PC BIOS, so that the system starts even without the keyboard. The correct configuration is “Halt On: All But Keyboard.”

4.2 First-time operation of Open-E Data Storage Server

Now start your system.

After a connection has been established, all settings can also be changed remotely via the web browser. If your network requires it, the address of the standard gateway and the broadcast address can be changed.

For additional information, please read the chapter “Console display functions”

4.3 Logging into Open-E Data Storage Server

You can establish a connection to Open-E Data Storage Server from every network computer. To establish this connection, use a browser (e.g. Microsoft Internet

Explorer) and enter the IP address or the name of the computer hosting the Data

Storage Server into the URL entry line: https://192.168.0.220 (standard address) or https://dss (this name can be changed in the installation of Open-E Data Storage

Server settings).

For security reasons, Open-E Data Storage Server uses the encrypted SSL protocol (https).

You will now be asked to verify the encryption certification. Since Open-E Data

Storage Server only allows to create shares on the Intranet, there is no need for global certification by an authorized body. You can accept the certificate for the session only, but also for all future sessions.

Now you have to accept the license in order to use the Open-E software and you can choose the language you want to use.

13

14

After you first launch Open-E Data Storage Server you will see a page with the software agreement and available language options. Later you can change the language used by modifying language settings, which are located in the Server tree accessible through “Setup”.

After accepting the license agreement you can log into Open-E Data Storage Server using the standard password “ admin ” (this can be changed later). In order to start working, you can now set all the necessary parameters.

The password is case-sensitive. If you cannot log into Open-E Data Storage

Server, please make sure the Shift and Caps Lock keys are not pressed.

If your web browser shows something different than expected, please delete the cache and cookies in the settings menu of your web browser.

4.4 Create Disk Array

If your system has a hardware RAID, please create a RAID array in the RAID controller setup. Please refer to the RAID controller manual. You do not have to install drivers or

RAID array monitoring and maintenance software. If your system has motherboard

RAID functionality, please do not use it as it is not supported.

In case you want to use software RAID with single drives or even with installed hardware RAIDs, please go to the “S/W RAID” tree in the “Setup” menu first. You will find a list of available units. A unit can be a single hard disk or disk arrays if you have a hardware RAID in the system. Software RAID can be created for a single hard disk or hardware disk arrays. To create a software RAID, please select relevant units, choose the RAID level and click on the “create” button.

15

After clicking the “create” button, the status will change to “in use” and additional information describing the kind of disk array (e.g. MD0 is RAID 0) will be displayed.

4.5 Adding Disk Array

• In the menu, please select the “CONFIGURATION”

Æ

”volume manager” and “Unit manager”.

• You will find a list of available drives/arrays (units) that can be used.

• When creating a new volume group, the system adds selected units only. You can use the default volume group name or change it. After creation is complete, the page is reloaded and the “Status” field shows your drives/arrays as "in use”.

• It is possible to combine two (or more) units into one volume group; by clicking on the volume

• If you want to use the snapshot feature you should create a snapshot volume. right-hand side of the tree diagram on the volume group name, e.g. “vg00,” and using the “Volume Manager” function you can create a new NAS volume and/or a new iSCSI

16

Next, using the “Volume Manager” function you can add a disk volume to a new LV, or increase the size of existing LVs (you cannot decrease LV size). To set the needed LV size just use the scrollbar. On the right side of it you will find a counter of available space. This function can be also used to reserve disk space for swap, snapshots, system and replication.

4.6 Creating Open-E Data Storage Server shares

In the upper menu, please select “CONFIGURATION” followed by “NAS settings.”

Here, you can select the authentication type. In smaller networks, authentication should be done via the used workgroup name, which has to correspond to the workgroup name of the client PC.

In the menu “CONFIGURATION”

Æ

“NAS Resources,” select “Shares” on the righthand side of the tree diagram. Now create the first share.

The workgroup/domain name that was configured in Open-E Data Storage

Server has to match the network settings. Otherwise, the configured shares will not be visible in the network environment.

If you made changes to the workgroup and server name in Open-E Data

Storage Server configuration, it can take some time until each workstation computer in the Windows network recognizes the new name.

4.6.1 Access to Windows Shares

Access to newly created shares is possible via the Windows Explorer. After entering the IP address of your Open-E Data Storage Server (in this example

\\192.168.1.200), all visible shares should be available immediately. Please keep in mind that sometimes it takes a few minutes until new shares or changes to become accessible.

When accessing invisible shares, you need to know the corresponding share name beforehand and attach it to the IP address with a backslash (\\):

17

Open-E supports Windows ACL (Access Control List) for read, write and execute options, based on the POSIX standard written by SGI.

Some examples on how to use ACL (with ADS or PDC authentication):

6. Allow “read” access to this directory for a group called "COMPANY":

a.

make sure that the group "COMPANY" exists

b.

in the security window click the "Add" button

c.

select the group "COMPANY" (Advanced

Æ

Find Now will show you all users and groups) and click OK

d.

enable "Read & Execute" in the Allow column

e.

click the "Apply" button

7. Create a “read only” directory with full access subdirectories for the group “ALL”

(using inheriting permissions):

a.

create a folder called "ROOT",

b.

go to the security window,

c.

remove both “Everyone” and your group,

d.

click the “Advanced” button and then the “Add” button,

e.

select the group “ALL” and click OK,

f.

change “Apply onto” to “This folder only”,

g.

within permissions leave only “Traverse Folder / Execute File” and “List Folder /

Read Data” Click OK,

h.

click the “Add” button once again and add “ALL” group,

i.

This time change “Apply onto” to “Subfolders and files only” (this step will put any inherited permissions into effect),

j.

select “Full Control” and click OK

k.

click “Apply” to save the permissions.

With these settings users from the group “ALL” cannot remove the “ROOT” folder or make any changes to its contents. All new files/folders will be based on the access given by inherited permissions.

Example:

- file /ROOT/some_file.txt can be changed but cannot be removed

- directory /ROOT/directory cannot be removed but a users from the group ALL can create folders and files in this directory,

- file /ROOT/directory/my_file.txt can be removed or changed by the group ALL

(provided the inherited permissions have not been changed)

8. Inherited permissions

If the file or directory has inherited permissions, all newly created subfolders will inherit the main folder permissions. All permissions can be changed. Please keep in mind that changing permissions in the main folder will trigger the same changes to the inherited permissions of any subfolder within.

New directories with no inherited permissions do not have ACL permissions at the beginning - they have only standard UNIX permissions

0777 (Windows 2003 shows every special permission in the normal view in

21

the security window. Windows 2000 does not show any permissions in the normal view - only in the advanced view). To enable ACL for this directory, first select “Full Access” for everyone and click the “Apply” button.

Subsequently do the same for your group and your user. Subdirectories created in this directory should have ACL permissions inherited from their parent. If permissions are inherited then the “ALLOW” column is grey. To disable permission just use the “Deny” column. If you change ACL permissions always check that a new set of permissions for one group does not interfere with permissions for other user/groups or any connections between these accounts. Windows 2003 handles such changes much better than Windows 2000.

**** Kerberos is a server for distributing security keys. Normally it resides only on the domain but it can also be located on an external server. In Windows

2003 this server ignores specified key types, and authorization works only when entering the IP address, not the DSS name.

4.7 Creating Open-E Data Storage Server iSCSI targets volume

After creating an iSCSI volume (see 4.5) , please choose “CONFIGURATION”

Æ

” iSCSI target manager”, within the “Create new target” function click the “Apply” button to create a new iSCSI target.

22

Next in the “Targets” diagram click on the name of a target you have created (e.g.

“target0”) and within the “Target volume manager” function click the “add” button located by the logical volume in question,

23

Using the “Target volume manager” function you can add “target volumes” only within the scope of one volume group.

You can create as many logical volumes and as many separate iSCSI volumes (LUNs) are required (see step 8).

If you create 5 logical volumes, you may create one target with 5 LUNs or 5 targets with 1 LUN each, or 2 targets where e.g. 3 LUNs belong to the first target and the remaining 2 LUNs belong to the second one.

By clicking on “CHAP users” in the left hand pane you can manage secure access to logical volumes by inputting a CHAP user name and password (password must consist from 12 to 16 characters if you use Microsoft iSCSI Initiator).

4.7.1 Configuring end user workstation

For iSCSI technology to work correctly on end-user computers, you need to install the iSCSI Initiator software (if it is not provided with the operating system). For Microsoft

Windows 2000/XP/2003 systems, the Microsoft iSCSI Initiator is available for download from the web.

Correct software configuration consists of installing individual target volumes by adding new disk letters in the system (in Windows XP and 2003) or subfolders as with folders in the UNIX system. All these functions are available via “administrative tools”

Æ disks management.

How to connect iSCSI in Windows 2000/XP/2003: a.

first, you have to install the iSCSI Initiator package. You must be logged in as an administrator to install the Microsoft iSCSI Software Initiator package,

b.

next, launch the iSCSI Initiator software,

c.

if you have set passwords on iSCSI and Target Access, click on “Secret” within the

“General” tab, enter your passwords, and after entering each click “OK” button (your passwordis called a “Target secret”),

d.

click the “Add” button on the “Discovery” tab, then enter your Open-E Data Storage

Server IP address,

e.

next click the “Advanced…” button and check “CHAP logon information,” next put in the User name and the Target secret and then two times click the “OK” button,

f.

on the “Targets” tab you will see name of available iSCSI targets, e.g.

“iqn.2006.10:dss.target0”,

g.

click “Log On” button, and if you have entered a password, you need to repeat the steps outlined in point “e,” then press the “OK” button. The status for the chosen target will now change to “Connected,”

h.

next choose Settings

Æ control panel

Æ

administrative tools

Æ computer management

Æ disk management,

i.

now all available iSCSI target drives will be displayed. In order to use them you have to format them and mount them in the system under a new disk letter.

Microsoft iSCSI Initiator ver. 2.02 does not support dynamic disks. Target password must consist of minimum 12 and maximum 16 alphanumeric characters. Please read the manual and release notes for the Microsoft iSCSI

Initiator for more details, which you can also find on the Microsoft website.

Please do not ignore the time settings on the Open-E DSS iSCSI target and the client stations. Those settings must be identical. Time can be synchronized using the “Set time function in the Web interface menu Setup.

5.2 Functions of Open-E Data Storage Server via browser access

The following pages will thoroughly describe every function of Open-E Data Storage

Server. The functions are divided according to menu options, which are located at the top of the screen

5.2.1 SETUP

Within this tab you can manage network interfaces, administrator settings, hardware

RAID controllers, create disk arrays using software RAID, as well as find Fibre

Channel, iSCSI initiator, hardware and GUI settings.

5.2.1.1 Network

5.2.1.1.1 Interfaces

Here you can find the tree containing network interfaces. Click on the interface name to see more information about the selected interface.

Function: Server name

Server Name

Please enter a server name to clearly identify your server.

Comment

Here you can enter a short description of your server.

Server name and comment rules:

• please make sure the server name is unique in your network,

• select a server name that clearly identifies your new server,

• please do not use spaces and special characters such as

~!@#$^&()+[]{}*;:'".,%|<>?/\=`_,

• server name cannot consist of digits only,

• comment is not displayed on some systems.

27

Function: DNS settings

This function enables you to enter DNS addresses. Please use semicolons to separate addresses

28

Function: Create new bond interface

Bonding allows for load-balancing or fail-over for incoming and outgoing connections. Here you can create or edit bonding network interfaces.

In order to create a bonding interface:

• select the network interfaces you want to create a new bonding interface for,

• select the preferred bonding mode from the Create drop-down menu,

• select dynamic (DHCP) or static configuration for the network interface,

• if you want to get a DNS address dynamically, select get DNS,

• when using static configuration for a network interface, enter the IP address, netmask, broadcast and gateway. Afterwards, click the Create button and a new bonding interface will be created.

In order to take advantage of bonding more than one ethernet NIC needs to be plugged into the box.

Please note that MAC addresses need to have a 02 prefix, for example:

02:xx:yy:zz:vv:nn

Each network interface is characterized by the following fields:

Primary

A string (eth0, eth2, etc) specifying which slave is the primary device. The specified device will always be the active slave while it is available. Only when the primary is off-line will alternate devices be used. This is useful when one slave is preferred over another, e.g., when one slave has higher throughput than another. The primary option is only valid for the activebackup mode.

Interface

Network interface name.

Cable

Shows if a cable is connected to the NIC.

State

Characterizes the state of the network interface. NIC can be in a bonding or single state.

Bonding modes:

balance-rr

Transmissions are received and sent out sequentially on each bonded slave interface. This mode provides fault tolerance and load balancing. active-backup

Only one slave in the bond is active. Another bonded slave interface is only used if the active bonded slave interface fails. This mode provides fault tolerance. balance-xor

Transmission is based on the following equation: [(the source MAC address XOR'd with the destination MAC address) modulo (slave count)].

This selects the same slave for each destination MAC address. This mode provides fault tolerance and load balancing. broadcast

Transmits everything on all slave interfaces. This mode provides fault tolerance.

802.3ad

IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share the same speed and duplex settings. Utilizes all slaves in the active aggregator according to the 802.3ad specification. Requires a switch that supports IEEE 802.3ad Dynamic link aggregation. balance-tlb

Channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave. This mode provides fault tolerance and load balancing.

Using cards from different manufacturers or cards based on different chipsets in one bond team may cause low performance or unstable behavior.

29

Function: HTTP proxy

With this function you can enable or disable an HTTP proxy.

To enable an HTTP proxy:

• select "Use HTTP proxy"

• enter server name, port, username and password

• click "apply" button

Proxy server name should not contain the http:// prefix, port and the password. An example of a correct proxy server name:

www.server.com.

Function: IPSEC

IPSEC provides strong authentication and encryption for the connections. It makes nearly impossible to eavesdrop or forge the transmitted data.

IP

IP address (optionally with a mask) of the clients that will be allowed to connect to the iSCSI target.

Password

The Password cannot contain spaces, special characters like ' " ` or be empty.

Encrypted data transmission imposes considerable overhead and depending on the amount data transmitted can impact the performance significantly.

30

Function: Interface Info

Here you can view network interface info.

Function: IP address

Here you can set TCP/IP parameters for selected NIC.

Activate

You can activate or deactivate a network interface by setting this checkbox.

DHCP / Static.

You can use static or dynamic (DHCP) network interface configuration.

Get DNS

If you want to dynamically get a DNS address, select Get DNS.

When using static configuration of network interface, enter:

• IP address,

• netmask,

• broadcast,

• gateway.

If you set a new IP address, you will lose your connection with the server during activation and you will have to log in again. In the URL entry line of your browser, please enter the new IP address.

If you do not get access, please use the console to set a new IP address. In order to access servers in another subnet, you need to enter the address of the router as the gateway.

If you use an NTP server to maintain proper time and date, please make sure you have appropriate gateway and DNS settings.

When creating a bonding interface, a new branch called “bond0” will appear on the left hand side of the screen. By clicking on it you can modify bonding settings (see below).

31

Function: Bond interface settings

Here you can configure bond interface settings.

To remove a network interface from bonding, tick the Remove field next to it followed by Apply. By unchecking the Active checkbox you can deactivate the bonding. Below, you can change the network configuration (static or dynamic

[DHCP]) for the bonding interface.

Each network interface which belongs to a bonding interface is characterized by the following fields:

Primary:

A string (eth0, eth2, etc) specifying which slave is the primary device. The specified device will always be the active slave while it is available. Only when the primary is off-line will alternate devices be used. This is useful when one slave is preferred over another, e.g., when one slave has higher throughput than another. The primary option is only valid for active-backup mode.

Interface:

Network interface name.

State:

Shows if NIC is connected.

Interfaces which have Virtual IP configured are disabled.

Using cards from different manufacturers or cards based on different chipsets in one bond team may cause low performance or unstable behavior.

Function: Remove bonding

Here you can remove a bonding interface.

5.2.1.1.2 iSCSI Failover

Here you can view list of active interfaces including bonding for which you can configure Virtual IP.

In this section you won't see interfaces which has been already assigned to bond interfaces or are inactive.

Function: Virtual IP Settings

With this function you can view the MAC address and assign virtual IP settings for your chosen interface. The virtual IP is shared between the failover nodes.

For example,

primary node

has the IP address

192.168.1.1

, while

secondary node

's address is

192.168.1.2

. The virtual IP address is

192.168.1.3

. In this situation, the

primary node

(the active node) will be available under

192.168.1.3

. In case of

primary node

failure, the

secondary node

will take over the

192.168.1.3

address.

address to ensure all connections can continue to the same

Virtual IP needs to be unique within its network environment and the same on both nodes (Primary and Secondary).

32

Changes to virtual IP settings can be done only when failover configuration is not active.

Virtual IP can be in a different subnetwork than the node IPs, e.g.

192.168.2.1

as opposed to

192.168.1.1

and

192.168.1.2

.

33

Function: Auxiliary connection

This option is used to configure the interfaces on which the iSCSI Failover sends UDP broadcast traffic. More than one interface can be specified.

If no interfaces are indicated in this field, the system will trace a signal to the opposite node and attempt to select a successful connection method automatically.

Function: Failover Status

This function displays failover statistics. These include:

• failover initialization status (

• node status (

service running primary/secondary

• ping node accessibility status ( and

ping node

)

,

),

active/passive

),

• connection status for the network interfaces configured to communicate within the failover,

Additionally, the function displays the statistics for the tasks taking part in the failover. The tasks are run exclusively on active nodes.

Switching a node into active state causes the tasks to be executed and the virtual IP addresses to become operational.

34

Function: Failover Configuration

In this section you can configure your system as either the Primary or the

Secondary node.

Primary node on localhost :

1. Secondary node IP - designates the IP of the system which has already been configured as the Secondary node.

2. Warn time - specifies how much time (in seconds) should elapse until the failover functionality issues a warning.

3. Dead time - sets the failure (death) detection time. The dead time directive is used to specify how quickly the system should decide if a node in a failover is dead. Dead time must be smaller or equal to Init time.

4. Init time - sets the initial dead time detection interval. The init time parameter is used to set the time which elapses until a failover node is declared dead and the Secondary node becomes the Primary. If the

Primary node becomes available before the init time runs out, the state of the failover nodes will not change.

5. Keep alive time - sets the failover keep-alive interval, i.e. the frequency at which failover state packets are sent between nodes.

Secondary node on localhost:

Primary node IP - designates the IP of the system which will be configured as the Primary node.

Ping node IP:

A ping node is a pseudo-member of a failover. It is located outside of the failover and serves to answer ICMP requests from failover members. (this means the ping node cannot be either the primary or the secondary node).

It is there to make sure the outside connection for the failover members remains online. For instance, if the ICMP request from the active node to the ping node fails, a similar request is performed by the passive node. If this one succeeds, the nodes perform the failover. The ping node needs only to be able to receive and reply to ICMP echo requests.

Serial port:

This options allows you to connect the node via a serial cable. Select the port to which the given cable has been connected.

Keep failover functionality after volume replication failure:

When activated, this option will allow automatic failover to be carried out after the volume replication between the nodes has been broken. Please note that in certain circumstances this may lead to data loss. Details can be found in the pop-up window which appears after ticking the checkbox for this option.

Warn, dead and init timers are started simultaneously.

Configuring the cluster with low warn, dead and init timers may result in unstable behavior. Optimal timer settings are dependent on server hardware and network topology. It is recommended to test different timer settings for optimum performance.

Before starting failover please make sure the LUN configuration is the same on both nodes, i.e. that the LUNs are of the same size and type

(block I/O or file I/O) and that the LUN order is preserved.

WARNING: Inconsistencies in this area may lead to data loss!

If you see the following error message: Service is under heavy load or the time values you have set are too low , you need to readjust the time values (they are dependent on your network connectivity and system load). When using low deadtine value, one of your nodes may wrongly assume the other one is dead, which will lead to a situation where both nodes are active (the so-called "split brain").

Please observe the following guidelines for deadtime value tuning:

• set the keepalive time to 1000 ms, it should be lower than warntime ,

• set deadtime to 60 s,

• set warntime to half the deadtime value you wish to use,

35

• observe the messages in the error box (lower left-hand corner of the Web GUI) or your email, if you have set up email notification for failover. If there are no relevant warnings, your proposed deadtime is fine and you can skip to the next step. Otherwise, set warntime to the longest time interval between the hearbeat packets as indicated in the error box. If the errors persist, increase warntime further. Please note deadtime always needs to be greater than warntime ,

• set deadtime to double the current warntime value,

• set warntime to slightly less than deadtime .

36

Function: Failover Tasks

This function displays all available tasks for iSCSI volumes. In order to select a task for a failover, move the selected task to the Failover Tasks column.

Please note any changes can only be made before the failover is initialized in the Failover manager function. To remove a task during failover operation, go to CONFIGURATION

Æ

Replication tasks .

The function is available only on the primary node.

You can only move a task to the Failover tasks column when the secondary node has an appropriate reverse task set up.

Failover quick start guide a.

Set up volume replication on the primary and the secondary server.

b.

On both systems, create a new target with exactly the same:

• Target Name (Example: iqn.2008-11:mirror01)

• SCSI-ID (Example: dF5NU3iE8ZAcK2XQ)

• LUN# (Example: 0) and assign the failover volume clicking on the "+" button.

Every time you disconnect a LUN from a target (clicking on "-" button)

the SCSI-ID and LUN# will be reset to the original default values. So, before clicking the "+" button again, please copy & paste the SCSI-ID and LUN# from the primary to the secondary system. Make sure the primary and secondary system have identical settings. Different settings can cause some initiators to lose connection to the target during failover.

c.

From the GUI menu of both systems, enter SETUP -> iSCSI Failover ->

[interface_designation] and configure the network interfaces to be used for failover purposes. To enable the Virtual IP select an interface card and click on the Enable Virtual IP box Enter the Virtual IP address, net mask

and the broadcast IP address Click apply The same must be dome on the secondary server.

d.

Please note that one of the interfaces in each system needs to have the

virtual IP

(the same for both nodes). In addition, there need to be at least two

5.2.1.4 S/W RAID

Function: Unit rescan

This function rescans your system for new units.

Function: Create new S/W RAID unit

With this function you can create software RAIDs from out of free (unused) units.

If you want to create RAIDs from used units which have already been in use, you need first to delete the contents of these units in the console first, however please be aware this will ERASE all data from the units.

44

To create a RAID select corresponding units, then use the RAID type and Chunk size menus to configure the new RAID. After setting all required parameters press the Create button.

Allow to create degraded mode

This option allows you to create a RAID1 with one unit, a RAID5 with two units or a RAID6 with three units, even if the minimal number of units is not met.

Chunk size – the minimal portion of data that is written at a time.

Available RAIDS:

RAID 0: a stripe array; requires [minimum] 2 units. In RAID 0 you can set a chunk size from within 4k ÷ 256k. The destination size of the RAID array will be the sum of the size of each drive in the array

RAID 1 : a mirror array; requires 2 units. Destination size will be equal to:

(SINGLE) UNIT_SIZE, where (SINGLE) UNIT_SIZE is the size of the smallest unit in the array.

RAID 5: a stripe + parity algorithm array; requires [minimum] 3 units with the same capacity. You can choose the following from the drop-down menus: (layout) parity algorithm [left/right] [symmetric/asymmetric].

DESTINATION SIZE: (NR_OF_UNITS-1)*(SINGLE)UNIT_SIZE, where

(SINGLE) UNIT_SIZE is the size of the smallest unit in the array

The (layout) parity-algorithm in RAID 5 is described below.

RAID 5 (layout) parity-algorithm

It is possible to set one of four algorithms for placing data and parity blocks in the matrix. The default option is left-symmetric, which is the best algorithm for large reads. Another recommended value is left-asymmetric.

Software RAID 5 is not a good choice for writing a lot of very small files!

To remove a RAID which has been previously added to a volume group, please enter the Extended Tools in the console (press F1 in the console to list keyboard shortcuts) and first delete the volume group for the RAID in question(the respective function is Delete content of units in the Extended Tools menu). This will enable the Remove button. Otherwise simply press the Remove button.

You can add spare units to RAID1, RAID5 and RAID6 arrays.

Please remember that after creating a RAID, the Info function will show the synchronization progress. Until this process is finished all actions performed on this array will be slower.

If units come from the same storage (Fibre Channel or iSCSI), efficiency will drop when using software RAID with them. To achieve optimal performance, you should use units that come from at least two different storages (for Fibre Channel or iSCSI connections).

Function: S/W RAID e-mail notification

It is possible to send notification by e-mail about events on software RAID arrays

(e.g. rebuild started, rebuild finished, RAID degraded). In order to do so please check the Send array events box..

In order to be able to send array events via e-mail you must first enable

“E-mail notification” in “setup”

Æ

“administrator”.

Include resyncing/recovering progress

This enables information about resync/rebuild progress to be sent via e-mail, provided that any such processes are taking place. E-mail will be sent for every 20% done.

Include array status

Information about the status of event-related array will be added every event.

Function: Drive identifier

This function has been designated to assist you in finding disks in your NAS server cage.

If you have a hardware RAID installed, the whole RAID array is shown as a single drive, so you may not be able to determine which drive unit represents which disk when using the S.M.A.R.T. tool or a hardware RAID management tool

(depending on the manufacturer of the RAID controller).

46

When you click on the Apply button, the appropriate disk will start reading and you can determine which disk it is by watching the disk-activity LEDs. For this function to operate properly there should be no other activity in progress on the hard drives in question.

Identification will stop automatically after one minute if you do not stop it before (by unchecking the appropriate option and clicking Apply). Using this function during normal operation is not recommended and will cause your server to slow down.

After clicking on “MD0” in the left hand pane a tree with the available software

RAID units will be displayed.

47

Function: Manager

In this function you can manage the RAID array.

Available operations:

RAID 0:

Failed. If any of them are, the whole array will be disabled.

RAID 1:

• To mark a unit as Faulty check the appropriate option (in the F column) and click

Apply.

• To delete any unit from an array check the appropriate option (in the R column) and click on Remove

RAID 5:

• To set unit as a Faulty one mark proper checkbox (in the column F) and click on

Apply button.

• To delete any unit from an array mark proper checkbox (in the column R) and click on Remove button.

RAID 6:

• To mark a unit as Faulty check the appropriate option (in the F column) and click

Apply,

• To delete any unit from an array check the appropriate option (in the R column) and click Remove,

RAIDs notation:

• PR - priority in array - represents the priority of a spare unit which will be added to the array if another unit is marked as Faulty. The higher the priority, the sooner will this unit be used,

• F - faulty - unit can be removed from the array,

• R - hot remove - unit can be removed from the array without shutting down the system,

• ST - characterizes the state of a unit in the array, which can be:

• A - this means that unit is active in an array,

• * - unit number within the array,

• S - spare or spare rebuilding - this means that the unit is free and can be added to an array or is free and currently rebuilding.

Limitations:

• There is no possibility to set any unit as Faulty if the matrix is degraded or during resync/rebuild.

• When using RAID 1 and RAID 5 there is a possibility to mark only one disk from among active disks as faulty. This regulation is not valid for spare units in an array.

Only one disk from within the active group in an array can be marked as

Faulty or Removed

Function: Info

Using function you can obtain the following information: Creation Time, RAID

Level, Array and Device Size, Update Time and State.

indicator will appear near the one(s) enqueued. Using the button next to the indicator you can send the initializing volume to the back of the initialization queue. Every volume that is waiting for initialization in queue can also be sent to the back of queue.

Blocksize

This option is available when creating a Fibre Channel volume (FC). Blocksize indicates the nominal size, expressed in bytes, of a block of data. Possible values:

• 512 bytes

• 1024 bytes

• 2048 bytes

• 4098 bytes (default)

Blocksize has an influence on performance and space management. The greater value the better performance, but data might take up more space. This option is unavailable when expanding an FC volume and for FC snapshots.

When adding each new unit there will be 4 GB space reserved for swap

(if a swap has not been already created). Additionally, 1 GB of space is reserved for internal system use.

Function: Snapshot definition

Here you can set the logical volume to which the snapshot will be assigned.

Name

Snapshot name.

LV

Select Logical volume to which snapshot will be assigned. If Logical volume has no snapshot assigned yet, then in LV field will be "unassigned".

Status

Snapshot status. Can be one of the following:

Active

Snapshot is active.

Inactive

Snapshot is inactive, probable reason: overflow.

Unused

Snapshot is currently unused.

The snapshot function enables the system administrator to freeze the data content of the volume at a certain time. From this moment on, the users work on a virtual data volume, all changes to the volume are stored in a different partition.

The storage of all changes is independent of the filesystem - it takes place on the block level. Snapshots can be created (active state) /removed (unused state) manually or automatically.

Please be reasonable when you are calculating the space reserved for snapshots. Please set as much space for a snapshot as you expect to change during snapshot activity, e.g. when you are performing a backup from a snapshot which takes one hour please set the size of this snapshot to as much space as will be changed during one hour. The snapshot will become inactive if the contents (data changed on logical volume) exceed the snapshot capacity. You do not lose data in that case. However, the old dataset, which has been frozen with the snapshot, is not available any longer.

When you define a schedule, use only as many snapshots at the same time as actually needed. A large count of active snapshots can slow down the system considerably.

Manual creation and removal of snapshots can be done via the following path: CONFIGURATION

Volume manager

Æ vg[nr]

Æ

Function: Volume Manager.

How to access NAS snapshot

After a snapshot has been created and activated, you can access it by following these steps::

• Go to menu CONFIGURATION

Æ

NAS settings menu and select the network protocol on which the snapshots will be accessible, exactly like all other shares.

This needs to be done only once. When establishing access to a snapshot the second time, this action is not necessary. You can activate access to snapshots on the following protocols:

• NFS,

• SMB (Network neighborhood),

• FTP,

• AFP.

• create a new share that will be assigned to the activated snapshot,

• go to the CONFIGURATION Æ NAS resources menu,

• within the Create new share function:

• enter share name,

• use the Specified path option and select the snapshot that you want to have access to,

• click Apply to create a share,

• now you can start to explore your share(snapshot) using the specified network protocol.

How to access iSCSI target snapshot

After a snapshot for an iSCSI target has been created and activated, you can access it by following these steps:

• Go to menu CONFIGURATION

Æ iSCSI target manager

Æ

Targets

Æ

[target_name] menu,

• enter the Target volume manger function and click the Add button on the right side of the snapshot you would like to have access to. A new LUN will be added to the target,

• now you can connect with your iSCSI initiator and use your snapshot target,

• here is an example (Microsoft Windows environment): please download

Microsoft iSCSI Initiator and follow its instructions,

• start the software and add targets,

• access the Target Portals menu and enter the IP address of the iSCSI server and the socket (default 3260),

• in the Available targets menu please log into a previously added target,

• now your snapshot target will show up in your system and you can use it.

61

Function: Volume replication mode

Here you can set the replication mode for every logical volume (with replication functionality available). A volume can be in a source (S) or a destination (D) replication mode.

You can also clear the metadata (CM) of a volume. Metadata describes the replication data.

Clearing metadata is required when you want to start the replication process from the beginning. Another usage example is when the data on the source volume is inconsistent and you want to restore it from the destination volume. In this situation you need to switch replication modes between the volumes (i.e. the destination volume should now be in source mode, while the previous source should be switched to destination mode). Before starting a replication for a new source and destination please clear the metadata from the previous destination volume. When replication is complete the data on the previous source volume will be consistent. If a volume is set to the destination replication mode then it will not be visible in the iSCSI initiator.

62

Function: Mirror server IP

Here you can set the IP address for a mirror server. It needs to be entered in order to define the volume replication task.

Setting the source IP address on the destination server is for security reasons.

This will allow only the source IP address to send data to the destination target.

Function: Create new volume replication task

Using this function you can create a volume replication task. This creates a mirror copy of data from the source volume to the destination volume in real time, meaning that if you, for example, create a file on the source volume the same file

will be created on the destination volume. Destination and source volumes need to be the same size in order to successfully perform the replication. Replication can be performed only between two mirror replication servers.

Please note this function allows you only to create replication tasks. In order to enable them, use the Replication Task Manager function.

Please enter the task name, select the source volume and the destination volume. Click Create in order to create a replication task.

Volume replication process runs on randomly selected ports from

12000- 13999.These ports have to be open in firewalls for both incoming and outgoing traffic.

Function: Replication tasks manager

Here you can run, stop and delete existing replication volume tasks. When a replication task is running you cannot change the replication mode for the logical volume, delete the metadata or change the mirror server IP address. You need to stop the replication process first.

5.2.2.2 NAS settings

64

Function: Authentication method

The server administrator can choose one of the following authentication methods for the users:

Workgroup (internal LDAP)

With this method you need to create all user/group accounts in the NAS

Resources menu. In the Workgroup field please enter your network workgroup name. New users are assigned to the default group called Users .

Workgroup (external LDAP)

In the case of external LDAP (Lightweight Directory Access Protocol) the NAS server imports users/groups from an external LDAP server. Please fill in all fields accordingly. In the Show advanced list you can set the Base DN, and the LDAP administrator DN (Distinguished Name) and password. Base DN should look like this: "dc=server,dc=nas" (DC - Domain Component), where "server" and "nas" can be set exactly as they are set on the remote LDAP server. In the LDAP administrator DN field you should enter the base DN (as above) with an additional prefix such as "cn=admin," (CN - Common Name). Users should be stored in the Organization Unit (ou) "People," groups in "Groups" and computers in "Computers."See sample organization tree below:

Windows (PDC)

In this case the NAS server will use the Windows Primary Domain Controller user database for user authentication. This method can be used with NT4/2000/2003 servers. If a Windows 2000/2003 server runs the ADS native mode, please use the Widows (ADS) method.

If you encounter problems getting connected to a PDC server running under NT4, please get connection follow the instructions below:

1. run the Server Manager program from the Start menu

Æ

Programs Æ Administrative Tools (Common) Æ Server

Manager .

2. in the Server Manager menu select Computer -> Add to

Æ

NAS settings ,

6. choose Windows (PDC) as the authentication method,

7. in the Server IP field enter the NT server IP address,

8. in the Name and Password fields enter the NT4 administrator account name and password,

9. click Apply . WARNING: If the connection fails, you will need to restart the process (go back to point 1).

Windows (ADS)

This option can be used for Windows 2000/2003 ADS servers:

• Please enter the realm name of your Windows 2000/2003 server. It can be found in the Windows system by clicking the right mouse button on My Computer and selecting Properties , then clicking the Computer name tab. Realm name is the same as the domain name.

• The KDC IP address must be taken from the same system as the realm name.

• Enter the administrator login and password,

• Click Apply to connect to the Windows (ADS) domain.

In order to connect to an NAS share via AFP (AppleTalk Filing Protocol) while user authentication is set to ADS (Active Directory Services) and the Mac workstation prompts for username and password, please enter the username as follows:

User Name: DOMAIN_NAME+USER_NAME (the "+" character belongs to the syntax!)

DNS server IP should be the same as the domain controller IP!

Workgroup (NIS server)

Please choose this option if you want to use a user/group database from a

Network Information Service server.

65

1. Workgroup name cannot begin/end with space and cannot contain special characters such as:

~!@#$^&()+[]{}*;:'".,%|<>?/\=`

2. When changing the authentication method you run the risk of losing ACLs (Access Control Lists). In this case please set user/group access rights for every share and reset ACLs.

3. If SMB authentication is enabled, please edit the Windows registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\la nmanworkstation\parameters\ and change the value of the

DWORD 'enableplaintextpassword' key to '1' hexadecimally.

Function: NFS settings

Click Use NFS to enable access to shares and/or snapshots via NFS.

Network File System (NFS) is a protocol for distributed file system which allows a computer to access files over a network as easily as if they were on its local disks.

If the hosts file has an entry in the DNS field but does not have the reverse DNS entry then the connection to NFS will not work.

66

Function: FTP settings

To enable FTP services check Use FTP.

FTP port

Determines the port the FTP service is listening to.

Max clients

Limits the total number of concurrent FTP connections.

Max clients per host

Limits the total number of connections originating from a single host.

Min. port

Minimal port number for the FTP passive mode. Needs to be smaller than the maximum port number.

Max. port

Maximal port number for the FTP passive mode. Needs to be greater then

1024.

Encryption settings

SSL

Data transfer will be encrypted with the SSL protocol.

None

Data will be send without any encryption.

Advanced settings

Idle timeout

This option allows you to set a timeout (in seconds) for an idle connected client. An idle client does not receive any data on either the control or the data connection. Inputting 0 equals no timeout.

No transfer

This option allows you to set a timeout (in seconds) for a connected client whose data connection is idle (e.g. it is not sending or receiving data).

Control connection is not subject to this timeout. Inputting 0 equals no timeout.

Passive port range

Range of port addresses when FTP service is connected in passive mode.

FXP support

Enables support for the File eXchange Protocol.

Delay engine on

Enables runtime delay. It is recommended to keep this option on for security purposes.

The possibility to access the server via FTP (File Transfer Protocol) offers additional flexibility, as users can access storage either from the Intranet or Internet. An FTP client (e.g. SmartFTP) is ideal, but the Internet

Explorer or a similar browser is also suitable.

To establish a connection, the FTP client needs several pieces of data:

• IPaddress: 192.168.0.220 (this is the standard address)

• Port: 21

• User: anonymous

• Password: 123

Access rights allocation is done via the IP address of the PC currently in the process of accessing. Read access is therefore granted on the basis of these usually typical and anonymous login data. As a standard, the FTP server uses port 21, but that can be changed via the FTP port setting. If you use the Internet

Explorer when accessing, you need to enter the following data into the address line:

ftp://192.168.0.220

following way: new port number).

. You will not be prompted to enter the username and password, as the Internet Explorer first establishes an anonymous connection. If you have changed the FTP port, add this information to the address line the

ftp://192.168.0.220:4711

(in this example, 4711 represents the

How to enter IP address

In order to allow specific computers access enter the privileged IP addresses separated by semicolons.

For example: 192.168.0.1; 192.168.0.2; 192.168.0.222; etc.

In order to assign writing privileges to the entire address area between

192.168.0.1 and 192.168.0.254 enter:

Function: AppleTalk (AFP) Settings

Here you can activate the AppleTalk protocol in the network to access shares on the NAS Server.

68

Function: SMB settings

This function allows you to edit SMB protocol specific parameters. There are several options you can change:

Wins server IP

If you have a WINS server on your network you should indicate the WINS server IP here..

Superuser

Superuser is a user who has the permission to take ownership of folders and files which belong to other users. These rights can be useful when an administrator wants to change access rights (ACL) for folders or files created by other users. To give superuser privileges to a user select them in the menu. Superuser privileges allow to modify, remove and add new files to the share. This includes all files and directories, even those the superuser does not have ownership of.

Simple and protected negotiation

Simple and Protected Negotiation (SPNEGO) is a negotiation protocol. If you use a PDA device to access shares on NAS please uncheck it.

To connect to your PDA device use netbiosname, not IP address.

Store DOS attributes (uses xattrs)

This option enables you to preserve all MS-DOS attributes using Linux xattrs attributes. It cannot be set when you are using the options Preserve hidden file attributes or Preserve system file attributes .

Preserve hidden file attributes and Preserve system file attributes (uses

ACLs)

These options enable you to preserve the following MS-DOS attributes: hidden and system. These attributes are mapped to x (EXECUTE) attributes for group and others in the Linux POSIX ACL. Windows ACL permissions are also mapped to Linux attributes. In order to avoid attribute mismatch, it is strongly recommended to disable these options. These cannot be set when you are using the Store DOS attributes option.

Hide special folders

This option hides special folders that are created by MAC OS/OSX systems.

With that option enabled, users cannot see MAC OS/OSX system files via the

SMB protocol

MAC OS/OSX system files:

6. .DS_Store,

7. .AppleDouble,

8. Temporary Items Network,

9. Trash Folder,

10. TheFindByContentFolder,

11. TheVolumeSettingsFolder,

12. .AppleDesktop,

13. .AppleDB,

69

14. Icon?,

15. .VolumeIcon.icns,

16. .FBIndex,

17. .FBClockFolder.

Changes to the ACLs and/or xattrs settings need to be confirmed seeing as these changes can make files invisible to users. It is not recommended to change these settings on severs that already have some data stored. If after changing the Preserve hidden file attributes

(uses ACLs) and/or Preserve system file attributes (uses ACLs) settings any files are not visible, users can use the following command which will remove the hidden attribute from the files:

attrib -S -H x:\*.* /s

/d

,where:

x

- network drive.

Any change to SMB settings will disconnect users that are currently connected. These also need to be accepted by users; the acceptance prompt will only appear if any users are connected to SMB. If the user clicks the Cancel button the settings will be saved but the connection to

SMB will not be reset

Function: NDMP data server

NDMP (Network Data Management Protocol) is a protocol for direct communication between NAS and backup devices. It bypasses the backup server, thus providing better speeds.

In order to use NDMP, click the Enable NDMP data server checkbox.

User

Enter here the user authorized to access the NDMP server. The same user name and password should be configured at the NDMP client software.

Password

Enter here the password for the authorized user.

Interface

Select the network interface to be used for the NDMP server.

The NDMP Data server can be used with the following software:

NDMPCopy

NDMPcopy transfers data between filers using the Network Data

Management Protocol (NDMP). When you use rsh to perform this transfer, the data flows from the source machine to the rsh host and then again from the rsh host to the destination machine. This can put a double load on the network and unnecessary load on the rsh host. With

NDMPcopy, data is transferred directly from the source machine to the destination machine, and the NDMP host and network are not burdened with the extra load. The program can be downloaded from the official

NDMP web site (http://www.ndmp.org).

NetBackup

NetBackup should be configured with following parameters:

• at least one NDMP host should be configured,

• at least one client of the /"NDMP, NDMP/" type should be added.

75

Steps for backup process in 3-way mode:

• it is necessary to run Device Configuration Wizard and add at least two NDMP hosts (the first is a source and the second is a destination with the tape drive). It is also possible to add NDMP hosts from Media and Device

Management/Devices/NDMP Hosts,

• next, create policy rules and set policy storage unit which is identical to the destination NDMP host,

• finally, set the ndmp client which is the origin for the backup process.

After the steps above have been completed the backup in 3-way mode can be established from the NDMP host to the storage unit through NetBackup management.

The Data Storage Server with the enabled NDMP Data server functionality can be used in the following data backup scenarios:

Server to server copy with NDMPCopy

The data can be moved between two Data Storage Severs using the

NDMPCopy utility.

To copy data user must define source and destination and authentication credentials for data servers. The command line for copying data is the following: ndmpcopy source destination [ options ].

Source has the following format: src_filer:src_dir, where src_filer is the name of the filer being copied from, and src_dir is the absolute pathname of the directory being copied. The destination has the format dest_filer:dest_dir, where dest_filer is the name of the filer being copied to, and dest_dir is the absolute pathname of the directory to which the source directory is being copied. The destination directory is created if it does not already exist.

Options:

• by the word user specification then text authentication is used. The default is text authentication with user root and no password.

•

•

•

•

-sa none | user:password source authentication none

. If this flag is followed

, then no authentication is used. If it is followed by a

-da none | user:password destination authentication

followed by the word followed by a user specification then text authentication is used. The default is text authentication with user root and no password.

-sport port none

. If this flag is

, then no authentication is used. If it is be left unchanged. The default is 10000.

-dport port

. NDMP port to use for the source filer. This should normally

. NDMP port to use for the source (DESTINATION?) filer.

This should normally be left unchanged. The default is 10000.

-dhost hostname

. The destination host for data transfer (if it is not the same as the destination NDMP host). This is useful if your destination host has multiple network interfaces and the bulk data should go over a different link than the NDMP connection. One example of this would be if the filers are connected to the host running ndmpcopy via a 10

Mb/s ethernet, but the filers are linked together by a 100 Mb/s ethernet as well. The hostname should be specified by:

76

•

•

•

•

-dhost

. The name or IP address of the interface on the destination machine.

-level 0 – 9

. Without the

-level

option ndmpcopy always performs a level 0 dump. When the

-level

option is provided the restore process is requested to "incrementally restore" the dumped files and uses the

restore_symboltable

file in the process so that incremental dumps can be carried out. Each restore will leave behind a file regardless of this option.

restore_symboltable

-v

. Increase the verbosity. The default (level 1) will display the dump log messages received from the dumping filer. One displays NDMP status information as well.

-v

(level 2)

-q

. Increase the quietness (decrease the verbosity). This flag will counteract any

-v

flags present. If there are more no status information will be displayed. Usually it does not make sense to specify both

-q

and

-v

-q

flags than

, but it is a possibility.

-v

flags,

Backup/restore with regular backup software

You can use the NetBackup application to backup the data through the

NDMP DATA interface. It is necessary to install the NetBackup server and client software as explained in the original NetBackup Install Guide.

Next, configure the NetBackup application to use the remote/local

NDMP server as follows:

• add and configure devices (robots for the tape managing, disk arrays, tapes),

• add the storage unit which defines the media on the NDMP host and the media server,

• create the NDMP policy and define:

• attributes,

• NDMP client to backup,

• path on this client to the backup,

• storage unit to be use,

• schedules.

This name is used to identify the drive. It is important to note that each drive name must be unique. Descriptive names are recommended. Drive names are limited to 48 characters.

Drive Name Rule

Select the Use Drive Name Rules checkbox to automatically create drive names based on the rules you specify. You can use drive name rules when a drive is first added to your configuration. The default drive name rule creates names in the format VendorID.ProductID.INDEX. For example, the default name for a

Quantum DLT8000 drive is QUANTUM.DLT8000.000. You can update the global drive name rule or create a local drive name rule. A global rule is stored in the EMM database and used on all connected device hosts. The global rule is used for the drive name unless a host-specific rule, or local rule, is specified.

Use any of the following drive attributes as part of a drive name rule.

• Host name

• Robot number

Cleaning Frequency.

NetBackup does not support cleaning drives in some robot types. If you want to set up a frequency-based cleaning schedule for the drive, set the number of mount hours between each drive cleaning. When you add a drive or reset the mount time to zero, Media Manager starts recording the amount of time that volumes have been mounted in that drive. If the drive is in a robotic library that supports drive cleaning and a cleaning cartridge is defined in that robotic library, cleaning occurs when the accumulated mount time exceeds the time you specify for cleaning frequency. The mount time is reset when the drive is cleaned. If you do not specify a cleaning frequency (the default frequency is zero), you can still use automated drive cleaning with the TapeAlert feature, provided the following conditions have been met:

• The drive supports TapeAlert.

• A cleaning volume has been defined in Media Manager.

• The host platform, robot type, and drive support drive cleaning.

If drive is robotic library specify option Drive is in robotic library and specify library parameters.

Robotic Library

This dialog box allows you to select any currently configured robotic library that can control the drive.

Robot Drive Number

Robot drive number specifies the physical location in the robot of the drive that you are adding. When adding more than one drive to a robot, you can add the physical drives in any order. For example, in a TL8 robot you can add drive 2 before drive 1. If you assign the wrong number Media Manager does not detect it initially, but an error will occur when the robotic control attempts to mount media on the wrong drive. Configuration of drives using the correct Robot Drive Number is important to the proper mounting and utilization of media. The Robot Drive

Number, commonly set based on correlation of the drive serial number with drive serial number information from the robotic library, should be determined and validated before the device configuration is considered complete.

Configuration of media used.

Media Manager volumes are logical units of data storage or cleaning capability on media that have been assigned media IDs and other attributes, which are recorded in the EMM database. The attributes in the database include information to show the robotic location. This residence information for a volume includes the robot host, robot type, robot number, and slot location.

85

In the NetBackup Administration Console, select Media and Device Management

Æ

Media. A media management window similar to the following appears.

86

To add a volume, the Volume Configuration wizard can be used.

To use robot inventory to add robotic volumes, perform the Update Volume

Configuration procedure. During the update, Media Manager assigns the media

IDs and other attributes. You can also configure volumes automatically by inserting the media into a standalone drive. For an unused volume, NetBackup assigns a media ID, labels the volume, and uses it (if it needs a volume of that type for a backup). Media Manager adds the media ID (designated by

NetBackup) and other attributes for the volume.

To add volume manually use Action

Æ

New

Æ

New Volumes.

Configuration of NDMP storage units

1. On the NetBackup master server, add an NDMP-type storage unit for the devices that will contain the backup data. In the NetBackup Administration Console, select NetBackup Management

Æ

Storage Units.

2. To create a new Storage Unit use Actions

Æ

New

Æ

Storage Unit . The New

Storage Unit dialog appears.

87

For Storage unit name, enter a unique name for the storage unit.

For Storage unit type, select NDMP.

For On demand only: This specifies whether the storage unit is available only when a policy or schedule specifically requests it. If this option is not used, the storage unit is available to any NDMP policy or schedule.

For Storage device, select the type of device for this storage unit.

For NDMP host, specify the NDMP host where the tape drive is physically attached.

Configuration of NDMP polices.

Backup policies define the rules that NetBackup follows when backing up clients.

A backup policy can apply to one or more clients. Every client must be covered by at least one backup policy. The best approach to configuring backup policies is to divide clients into groups according to any backup and archiving requirements, then create a policy for each group.

To display information about all policies on the current master server, click

Summary of All Policies. A summary of all polices appears in the Details pane, subdivided into panes displaying Polices, Schedules, Clients, and Selections. To display the general attributes for a specific policy, select that policy in the left pane. The Details pane shows the general attributes for that policy only. Doubleclick on a policy to display the attributes in tabs, available for editing.

The easiest way to set up a backup policy is to use the Backup Policy

Configuration Wizard. This wizard guides you through the setup process, simplifying the process by automatically choosing default values that are good for most configurations.

In the NetBackup Administration Console, select Master Server or NetBackup

Management.

From the list of wizards in the Details pane, click Create a Backup Policy.

1. In the NetBackup Administration Console, expand NetBackup Management Æ

Policies. Select Actions

Æ

New

Æ

New Policy.

To create a policy rules without wizard.

88

2. Type a unique name for the new policy in the dialog. Than a new dialog “Add

New Policy – policy name” appears:

It is necessary to specify the following policy attributes in it:

a.

Policy Type: NDMP

b.

Policy Storage Unit:

• If the NDMP host has more than one storage unit and you want to direct backups for this policy to a specific storage unit, specify the name of that storage unit.

• For a three-way backup, specify a storage unit that was defined for the target

NDMP host with attached tape.

• For NDMP backup to Media Manager devices, specify a Media Manager storage unit defined for a device connected to a NetBackup media server.

Specify the following parameters for every client in NDMP policy:

Hostname: Name of the NDMP host

Hardware and operating system: NDMP NDMP

Files:

The Backup Selections list must specify directories from the perspective of the

NDMP host. Two examples:

/home/dir1/

/vol1

The following Backup Selections capabilities are NOT supported for an NDMP policy:

• Wildcards in pathnames. For example, /home/* is an invalid entry.

• Individual file names. Only directory or volume names are allowed.

• Exclude list (because client software is not installed on the NDMP host).

You can specify any of the following backup types in a schedule for an NDMP policy:

• Full

• Cumulative Incremental

• Differential Incremental

Specify Override policy storage unit only if this client of NetBackup (the NDMP host) has more than one storage unit and you want to use a specific storage unit for this schedule. In this case, the client must be the only client in this NDMP policy.

Customize server preferences.

By default NetBackup for NDMP is configured to use Direct Access Recovery

(DAR). For each restore, NetBackup automatically determines if the use of DAR will speed up the restore. NetBackup uses DAR only when it will result in a faster restore. DAR can be turned off if desired. This may be necessary if you are having problems with DAR and your NDMP host is an older machine or is not running the latest NAS OS version. NetBackup restricts maximum files with DAR to 1024.

89

To change DAR setting in the NetBackup Administration Console, expand Host

Properties and click on Master Servers or Media Servers. Right-click on the name of the server and select Properties.

90

Click on “General Server”. Uncheck the Use direct access recovery for NDMP restores box, and click Apply. This disables DAR on all NDMP restores.

Backup process

Automatic Backup of an NDMP Policy

Use this item with properly configured NDMP policy scheduling.

Manual Backup of an NDMP Policy

Click on Policies. Right click on the NDMP policy name and select Manual

Backup from the pop-up menu. This opens the Manual Backup dialog.

91

In the Manual Backup dialog, select a schedule, then select the clients (NDMP hosts) that you want to back up. If you do not select any schedules, NetBackup uses the schedule with the highest retention level. If you do not select any clients,

NetBackup backs up all configured

NDMP hosts. Click OK to start the backup.

Restoration process

The administrator can use the Backup, Archive, and Restore interface on a

NetBackup server (master or media server) to restore files to the NDMP host from which they were backed up, or to a different NDMP host. On the File menu, click Select Files and Folders to Restore, then click either from Normal Backup or from Archived Backup (depending on whether you are restoring from a normal backup or an archive).

There may be a delay while NetBackup reads information about the backups and builds the list of files you can restore. The title bar of the window displays the names of the server and client used for the operation.

92

To select an item, click in the check box to the left of the item. A check mark indicates an item is selected; a diagonal slash mark indicates that only some items within a folder are selected. You can select items in the All Folders pane or the Contents pane.

To preview a list of the media required for restore, select Actions Æ Preview

Media. If the backup images required to restore the data are on disk storage units rather than removable media such as tape, no media will be listed if you try to preview media.

On the Actions menu, click Start Restore of Marked Files. The Restore Marked

Files dialog appears. The items marked for restore are listed in the dialog window.

93

Specify restore parameters and press Start Restore. A dialog appears, indicating that the restore began successfully and asking if you want to view the progress of the operation.

To view the status of the restore, click Yes in the dialog. The View Status dialog appears, from which you can view the progress of the restore. The restore may take a few minutes to complete. After starting a restore operation, you can close

Backup, Archive, and Restore and perform other tasks on your computer.

NetBackup will continue the restore operation in the background.

Using NetBackup to backup and restore special device files through

NDMPD

As described before in this guide, NetBackup does not allow you to add files in the Policies backup selection path. But to perform a backup of a single file (or group of files), you can add the path with a file name. Backup id: Treat it as a directory, but NDMPD handles this case properly and creates a correct backup image. Then to restore these files in the Backup, Archive, and Restore application, you need to select the image and check the desired file. Because

NetBackup treats all as directories, you have a folder which consists of a path and the name of a file. All parts of this path must be checked with a slash, not a check, as described in the picture.

94

On this picture, we can see the backup of a special file /dev/sdb1. This image looks like we’re doing a backup of the directory /dev/sdb1/. After selecting Start

Restore, the Restore Marked Files dialog appears.

You can see that NetBackup tries to restore to the /dev/sdb1 file sdb1 – but this is ok. NDMPD handles this case and restores the file /dev/sdb1.

95

Function: Data replication agent

This function enables the data replication agent.

It is mandatory to enable this function in order to replicate to the destination share.

Data replication is performed by the rsync application.

Function: Antivirus setup

• FSG (1.3, 1.31, 1.33, 2.0),

• Petite (2.x).

• mail files,

• MS Office document files,

• executables files.

The Use quarantine feature allows you to choose whether you want to move infected files to the default folder (quarantine_dir), which is automatically created on shares, or manually choose the quarantine directory on a previously created share.

To get to know more about the infected files examine the logs (you can download them in MAINTENANCE -> Hardware ). The relevant logs are the following:

• scan_shares_ANTIVIRUS_[antivirus_task_name].log for regular antivirus scanning,

• clamd.log for SMB online scanning.

If the Use quarantine option is disabled you will only be informed about the infected file.

Please note that antivirus scanning may decrease the overall system performance

Function: Local backup settings

This function enables local backup functionality.

After clicking on “Shares,” the “Create new share” function allows you to define a new share, set up a comment for it (optional) or set its path. You will find all existing shares organized below. You can edit them with a simple click. All parameters except the name are modifiable. If you need change the name, delete it and assign a new name.

96

Windows users will see the name of the share in their network environment folders when they click on the icon for the Open-E DSS server. Comments are only visible if the users take a look at the share properties, or if shares are listed in detail.

The path represents the physical location of the data on the Open-E Data

Storage Server share volume. The user does not have access to this information. In order to simplify the navigation through the directories, you can use the browser function.

Function: Create new share

To create a share, enter the share name, a comment (optional) and set its path. To use the default share path, leave the Default path box checked. If you want to use a specific path, please check the Specified path box and select path to the share.

97

Please do not use spaces and special such as:

~!@#$^&()+[]{}*;:'".,%|<>?/\=`,

The workgroup/domain name configured in the NAS settings tab has to match the network settings. Otherwise, the configured shares will not be visible in the network environment. If you have made changes to the workgroup and server name in the NAS configuration, it can take some time before each workstation computer in the Windows network detects the new name.

Function: Force user and group

This function allows you to force the selected user and group to be the owners of all objects created from this point on.

102

Function: “NFS share access”

Please click Use NFS to activate access to this share via NFS.

In order to mount this share via NFS, please use the following syntax:

mount -t nfs IP_addr:/share/share_name /local_mount_point

or

mount -t nfs IP_addr:/

share

/share_name /local_mount_point

Share is a keyword and must always be added to the syntax.

In order to mount a share in synchronous mode please use:

mount -t nfs IP_addr:/share_name /local_mount_point -o sync

or

mount -t nfs IP_addr:/share/share_name /local_mount_point -o sync

In order to mount a share in asynchronous mode please use:

mount -t nfs IP_addr:/share/share_name /local_mount_point -o async

or

mount -t nfs IP_addr:/share/share_name /local_mount_point -o async

When using synchronous mode, data is not stored in a buffer, but transferred at once. In asynchronous mode the data is first stored in a buffer and then transferred.

The name of the share is case sensitive in the mount syntax. It is important to exercise due caution in this respect, as otherwise you might not be able to access the share

You can use following NFS option fields:

Allow access IP

Please enter an IP address or an address range which should be allowed to access NFS. You can enter a single IP, multiple IPs separated by a semicolon, or an IP address range. IP addresses not be added to the Allow write IP list will have read only access.

Allow write IP

Please enter an IP address or an address range which should be allowed to write to NFS. You can enter a single IP, multiple IPs separated by a semicolon, or an IP address range.

Insecure

Allows incoming connections to originate from ports greater than 1024.

Synchronous

When this option is enabled, the local file system will wait for the data to be written to the NAS server. NFS performance will be lowered, however this will ensure that the data will be written directly to the NAS server and will not be stored in the system cache.

Insecure locks

Disables authorization of locking requests. Some NFS clients do not send credentials with lock requests, hence working incorrectly with secure locks, in which case you can only lock world-readable files. If you have such clients you can use the Insecure locks option.

All squash

Maps all user IDs to the user nobody and all group IDs to the group nogroup .

No root squash

Select this option to grant the client machine's root user the root access level to the files on the NAS server. Otherwise the client root will be mapped to the user nobody on the NAS server.

When you leave the Allow access IP and Allow write IP fields blank, all computers in the subnet will have write access to NFS. When you set the Allow access IP field and leave the Allow write IP field blank, the specified computers will have read only access and none will have write access. When you set the Allow write IP field without setting the

Allow access IP field, the specified IPs will have write access and all computers in the subnet will have read only access.

• xxx.xxx.xxx.xxx

• xxx.xxx.xxx.xxx;xxx.xxx.xxx.xxx; ....

• xxx.xxx.xxx.xxx/network_prefix_length.

Some Linux distributions have UDP as the default protocol for NFS. In case of problems, it is recommended to switch to TCP by using the

103

following syntax:

mount -t nfs -o tcp ip_address:/share /mnt/point

.

If the host has an entry in the DNS field but does not have a reverse

DNS entry the connection to NFS will not work

Function: Http share access

With this option you can enable http access for selected share.

When no entries are present in Denied access or Allowed access fields everyone is permitted to access the target. Specifying at least one entry in

Allowed access field excludes all the clients that do not match it from accessing the target. When you specify at least one entry in Denied access field, every

CHAP user or CHAP users from network class address are denied from accessing the target. When you specify any IP address in Allowed access field,

CHAP users from that address are allowed to access the target even if the same address has been specified in Denied access field. If you enter only Allowed access field then Denied access field will be automatically entered with 0.0.0.0/0 entry.

Please note that already active sessions to the target will persist regardless of the newly applied settings. You can ensure that the settings are forced immediately after you apply them by going to

Examples:

Deny access: 0.0.0.0/0

Allow access: 192.168.2.30/0;192.168.3.45

These settings deny access from every IP address or network class address, only addresses in the Allow access field are granted access to the target.

Deny access: 192.168.0.0/16

Allow access: 192.168.2.30;192.168.10.230;192.168.30.0/24

These settings deny access to any IP addresses from the network

192.168.0.0/16, grant access for IP addresses 192.168.2.30, 192.168.10.230, all

IP addresses from network 192.168.30.0/24 and all IP addresses that have not been denied in the Deny access field.

• active backup or replication task,

• created by time schedule or created manually.

Unused

Snapshot is available for backup or replication tasks also for time schedule or manual start.

A ctive

Snapshot is activated by backup or replication task also time schedule or created manually. In case the snapshot was created by backup or replication task: the point-in-time data is available for that task. In case the snapshot was created by time schedule or manually: the point-in-time data can be accessed via:

• NAS share (if the snapshot was assigned to NAS volume),

• iSCSI target (if the snapshot was assigned to iSCSI volume),

• FC group (if the snapshot was assigned to FC volume).

Inactive

Appendix B

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free

Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General

Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

166

The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND

MODIFICATION

0.

This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called

"this License"). Each licensee is addressed as "you".

A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables.

The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".)

"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library.

Activities other than copying, distribution and modification are not covered by this

License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does.

1.

You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

2.

You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a)

The modified work must itself be a software library.

167

b)

You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.

c)

You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License.

d)

If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.

(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the

Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library.

In addition, mere aggregation of another work not based on the Library with the

Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3.

You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public

License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices.

Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy.

This option is useful when you wish to copy part of the code of the Library into a program that is not a library.

168

4.

You may copy and distribute the Library (or a portion or derivative of it, under

Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machinereadable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange.

If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code.

5.

A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the

Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.

However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this

License.

Section 6 states terms for distribution of such executables.

When a "work that uses the Library" uses material from a header file that is part of the

Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law.

If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.)

Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6.

Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself.

6.

As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications.

You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things:

169

a)

Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions).

b)

Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.

c)

Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution.

d)

If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place.

e)

Verify that the user has already received a copy of these materials or that you have already sent this user a copy.

For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it.

However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute.

7.

You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things:

f)

Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above.

170

g)

Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.

8.

You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

9.

You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License.

Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it.

10.

.Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License.

11.

If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you

(whether by court order, agreement or otherwise) that contradict the conditions of this

License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

171

12.

If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the

Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

13.

The Free Software Foundation may publish revised and/or new versions of the Lesser

General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free

Software Foundation.

14.

If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

15.

BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO

WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS

AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF

ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,

THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A

PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND

PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE

DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR

CORRECTION.

16.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY

MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE

TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR

CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE

THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR

A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF

SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF

SUCH DAMAGES.

END OF TERMS AND CONDITIONS

172

How to Apply These Terms to Your New Libraries

If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License).

To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

<one line to give the library's name and a brief idea of what it does.>

Copyright (C) <year> <name of author>

This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free

Software Foundation; either version 2.1 of the License, or (at your option) any later version.

This library is distributed in the hope that it will be useful, but WITHOUT ANY

WARRANTY; without even the implied warranty of MERCHANTABILITY or

FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public

License for more details.

You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation,

Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

Also add information on how to contact you by electronic and paper mail.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker.

<signature of Ty Coon>

, 1 April 1990

Ty Coon, President of Vice

That's all there is to it!
