Chapter 1: Introduction
Overview
Thank you for choosing the Thecus IP Storage Server. The Thecus IP storage is an
easy-to-use storage server that allows a dedicated approach to storing and
distributing data on a network. Data reliability is ensured with RAID features that
provide data security and recovery—over multiple Terabyte of storage are available
using RAID 5 and RAID 6. Gigabit Ethernet ports enhance network efficiency,
allowing Thecus IP storage to take over file management functions, increase
application and data sharing and provide faster data response. The Thecus IP
storage offers data mobility with a disk roaming feature that lets you swap working
hard drives for use in other Thecus IP storage, securing the continuity of data in the
event of hardware failure. The Thecus IP storage allows data consolidation and
sharing between Windows (SMB/CIFS), UNIX/Linux, and Apple OS X environments.
The Thecus IP storage‘s user-friendly GUI supports multiple Languages.
Product Highlights
File Server
First and foremost, the Thecus IP storage allows you to store and share files over an
IP network. With a Network Attached Storage (NAS) device, you can centralize
your files and share them easily over your network. With the easy-to-use
web-based interface, users on your network can access these files in a snap.
To learn about the Web User Interface, go to
Chapter 4: Using the Thecus IP Storage > Web Administration Interface
FTP Server
With the built-in FTP Server, friends, clients, and customers can upload and
download files to your Thecus IP storage over the Internet with their favorite FTP
programs. You can create user accounts so that only authorized users have access.
To set up the FTP Server, refer to
Chapter 4: Network Service> FTP .
iTunes Server
With the built-in iTunes server capability, the Thecus IP storage enables digital
music to be shared and played anywhere on the network!
To set up the iTunes Server, refer to
Chapter 4: Application Server>iTunes Configuration.
Printer Server
With the Thecus IP storage‘s Printer Server, you can easily share an IPP printer with
other PCs connected to your network.
To set up the Printer Server, refer to
Chapter 4: External Devices Server>Printer Information.
Multiple RAID
7
Thecus IP storage supports multiple RAID volumes on one system. So, you can
create RAID 0 for your non-critical data, and create RAID 1,5,6,50 or 60 (depend
on model) for mission-critical data. Create the RAID levels depending on your
needs.
To configure RAID modes on the Thecus IP storage, refer to
Chapter 4: Storage Management >RAID Information.
iSCSI Capability
Thecus IP storage is not only a file server, but it also supports iSCSI initiators. Your
server can access Thecus IP storage as a direct-attached-storage over the LAN or
Internet. There is no easier way to expand the capacity of your current application
servers. All the storage needs can be centrally managed and deployed. This brings
ultimate flexibility to users.
To set up an iSCSI volume, refer to
Chapter 4: Storage Management > iSCSI
Superior Power Management
Thecus IP storage supports schedule power on/off. With this feature, administrator
can set at what time to turn on or off the system. This feature is a big plus for
people who want to conserve energy. Wake-On-LAN enables administrator to
remotely turn on the system without even leaving their own seat.
To schedule system on and off, refer to
Chapter 4: System Management> Scheduled Power On/Off

manufacturer) in power-on state.
Temperature Celsius
The current temperature of the hard disk in degrees Celsius.
Reallocated Sector
Count of reallocated sectors. When the hard drive finds a
Count
read/write/verification error, it marks this sector as "reallocated"
and transfers data to a special reserved area (spare area).
This process is also known as remapping and "reallocated"
sectors are called remaps. This is why, on a modern hard disks,
you cannot see "bad blocks" while testing the surface - all bad
blocks are hidden in reallocated sectors. However, the more
sectors that are reallocated, the more a decrease (up to 10% or
more) can be noticed in disk read/write speeds.
Current Pending
Current count of unstable sectors (waiting for remapping). The
Sector
raw value of this attribute indicates the total number of sectors
waiting for remapping. Later, when some of these sectors are
read successfully, the value is decreased. If errors still occur
when reading sectors, the hard drive will try to restore the data,
67
Test Type
transfer it to the reserved disk area (spare area), and mark this
sector as remapped. If this attribute value remains at zero, it
indicates that the quality of the corresponding surface area is low.

size is better for large files.
Data Percentage
The percentage of the RAID volume that will be used to store
data.
Create
Press this button to configure a file system and create the RAID
69
storage volume.
To create a RAID volume, follow the steps below:
1. On the RAID Information screen, clicks create.
2. On the RAID Configuration screen, set the RAID storage space as JBOD,
RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 or RAID 60
(depends on model)— see Appendix B: RAID Basics for a detailed
description of each.
NOTE
N8900/N12000/N16000 Series supports multiple RAID
modes and are capable of creating up to five RAID
volumes within a single NAS system.
3. Specify a RAID ID.
70
4. If this RAID volume is meant to be the Master RAID volume, tick the Master
RAID checkbox.
NOTE
In a multiple RAID configuration, one RAID volume must be designated as the
Master RAID volume. The Master RAID volume will store all installed modules. If
the Master RAID is changed to another location (i.e. assigning volume 2 to be
the Master RAID volume after volume 1 had been previously assigned), then all
modules must be reinstalled. In addition, all system folders that were contained
on the Master RAID volume will be invisible. Reassigning this volume to be the
Master RAID will make these folders visible again.
5. Selected whether the RAID volume will be encrypted or not.
The RAID volume can protect data by using RAID Volume Encryption
function to prevent the risk of data exposure. To activate this function, the
Encryption option needs to be enabled while the RAID is created and
followed by a password input for identification. Also, an external writable
USB disk plugged into any USB port on the system is required to save the
password you have entered while the RAID volume is being created. See the
screenshot below for details.
Once the Create button has been pressed with the Encryption checkbox
enabled, the following message pop-up will appear for confirmation.
After the RAID volume has been created, you may remove the USB disk until
the next time the system boots. The RAID volume cannot be mounted if the
USB disk with the encryption key isn‘t found in any system USB port when the
volume is accessed. To activate the encrypted volume, plug the USB disk
containing the encryption key and into any system USB port.
71
We strongly recommended copying the RAID volume encryption key to a safe
place. You can find the encryption key file from the USB disk in the following
format:
(RAID volume created date)_xxxxxx.key
WARNING
Please keep your USB disk in a safe place and also backup the encrypted
key.
There is no way to rescue data back if the key
is lost.
NOTE
With RAID volume encryption enabled, the system performance will go
down.
RAID volumes with encryption enabled will be displayed with a key lock
symbol next to volume ID name.
6. Quick RAID — Enabled the quick RAID setting is going to enhance RAID
creation time.
NOTE
We recommend using the ―Quick RAID‖ setting only if the hard disks are
brand new or if no existing partitions are contained.
7. Specify a stripe size — 64K is the default setting.
8. Selected the file system you would like to have for this RAID volume. The
selection is available from ext3, XFS and ext4.
72
NOTE
Single volume size supported:
ext3  8TB
XFS  48TB
ext4  36TB
9. Press Submit to build the RAID storage volume.
10. Press ―Yes‖ for RAID volume creation preparation. Then click ―Finish‖ to
start up with RAID volume building.
73
Building a RAID volume may be time consuming, depending on the size of
NOTE
hard drives and RAID mode. In general, if the RAID volume building process
is up to ―RAID Building‖, then the data volume is accessible.
WARNING
Creating RAID destroys all data in the current RAID volume. The data will be
unrecoverable.

RAID configuration is usually required only when you first set up the device. A brief
description of each RAID setting follows:
RAID Levels
Level
JBOD
RAID 0
Description
The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
Provides data striping but no redundancy. Improves performance
74
RAID 1
RAID 5
RAID 6
RAID 10
RAID 50
RAID 60
WARNING
but not data safety. RAID 0 requires a minimum of 2 disks.
Offers disk mirroring. Provides twice the read rate of a single disk,
but same write rate. RAID 1 requires a minimum of 2 disks.
Data striping and stripe error correction information provided.
RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one
failed disk.
Two independent parity computations must be used in order to
provide protection against double disk failure. Two different
algorithms are employed to achieve this purpose. RAID 6 requires
a minimum of 4 disks. RAID 6 can sustain two failed disks.
RAID 10 has high reliability and high performance. RAID 10 is
implemented as a striped array whose segments are RAID 1
arrays. It has the fault tolerance of RAID 1 and the performance
of RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two
failed disks.
RAID 50 combines the straight block-level striping of RAID 0 with
the distributed parity of RAID 5. This is a RAID 0 array striped
across RAID 5 elements. It requires at least 6 drives.
RAID 60 combines the straight block-level striping of RAID 0 with
the distributed double parity of RAID 6. That is, a RAID 0 array
striped across RAID 6 elements. It requires at least 8 disks.
If the administrator improperly removes a hard disk that should not be
removed when RAID status is degraded, all data will be lost.
Edit RAID

NOTE

Migrating a RAID volume could take several hours to complete

The RAID migration feature is available only when it is configurable.
Here is a list of limitation with RAID level migration function:
1. During RAID level migration, it is not permitted to reboot or shutdown
system.
2. For RAID migration from R1 to R5 or R1 to R6, all services will restart
and ―iSCSI‖ volume will be in read only mode but read/write of the ―user
data‖ will be possible during the operation.
NOTE
The migration scheme below is based on Thecus IP
Storage product‘s maximum possible combination.
For other model which supports less HDD, please
refer to the web UI while RAID migration operates.

NAS Stacking
The Thecus IP storage‘s capacity can be expanded even further using the stackable
function. With it, users can expand the capacity of their network storage systems
up to 5 other stack target volumes which are located in different systems. These
can be stacked through single network access like SMB or AFP acting as a share
folder type.
From the main menu, the stackable feature is located under ―Storage‖. Please refer
the figure below for reference.
A. Add a Stack Target Volume
From the figure above, click Add to access the stackable target device
configuration page. Please refer to the figure below:
82
With the added stack target you can ―Enable‖ or ―Disable‖
later depending on usage required.

Next, input the target IP address of the stackable device and click the Discovery
button. The system will list available target volumes from the inputted IP address.
Once the volume IP has been set, you may need to input a valid user name and
password to validate your access rights. If there is no user name and password
needed to access target volume, then leave it blank.
83
The Stacked Target name will become the network share name and will be
displayed through network access such as SMB. You may refer to the figure below
to see the result. Please note the naming limitation.
From the figure above, the Stacked Target name is ―pmmeeting‖. The figures
below show the result before and after via Microsoft Network Access when settings
have been completed.
No Stack Target

share name ―pmmeeting‖
84
The Browseable setting is the same method used for setting a system share folder.
It designates whether or not this folder will be visible through web disk. You may
refer to the figure below for reference when Yes and No are selected.
The Public setting will be set the same way as the setting for the system share
folder associated with the ACL permission is. If Public is set to Yes, all users will be
able to access it, and ACL button will be grayed out. If Public is set to No, the ACL
button will be available in the Stack Target List window.
Click Apply to save your changes.
B. Activate a Stack Target
After your settings have been applied, the system will bring you back to the Stack
Target List window as shown below. There is one stack target device that has
been attached into this stack master.
85
With this newly attached stack target device, you will see the information displayed
and also have access to several options to choose from.
In general, if the attached stack target device has been used by another Thecus NAS
as stack target volume, then the Format item will be display and system will
recognize it straight away and display its capacity. Otherwise, the Format item will
be available and the Capacity and Status items will show as ―N/A‖ and ―Unknown
file system‖ respectively.
Next, click Format to proceed with formatting.
After the format is completed, the stack target volume will be created successfully.
You will see the volume‘s capacity and status in the Stack Target List screen.
C. Edit a Stack Target
To make any changes to a stack target, click Edit for the corresponding stack
target, and the system will bring up the following dialogue window:
86
After your changes have been made, click Apply to confirm any modifications.
Once changes are applied, the associated information will be updated on the Stack
Target List window.
D. Stack Target ACL
If the stack target Public setting set to Yes, then the ACL button will be grayed out.
However, if Public setting is set to No, then the ACL button will be available for
you to setup user access permissions for the stack target.
The ACL settings will be exactly the same as the system folder that you may have
setup previously.
E. Reconnect a Stack Target
This is used to enable stack target devices that may have been disconnected due to
a power outage or a disconnected network. When this happens, the Reconnect
button will become available. To attempt to reconnect the stack target, click
Reconnect.
87
ISO Mount
The ISO Mount feature is a very useful tool from the Thecus products. With it, users
can mount an ISO file and have the export name display all the details from the
mounted ISO file.
From the main menu, the ISO Mount feature is located under ―Storage‖. Please
refer the figure below for reference.
Select the ISO Image Mounting function and the ISO Image Mounting window
will appear as shown here.
A. Add an ISO file
From the figure above, select an ISO file from the drop down share list.
After selection, the system will bring up the Mount table screen for further settings.
88
To mount the new ISO file, select one file from the list of files and input the desired
mounting name into the ―Mount as:‖ field. Click ―ADD‖ to confirm the completion of
the mounting. If nothing is input in the ―Mount as‖ ISO file export name field, the
system will automatically give an export name to the ISO file. The mounting name
will then be defined by the ISO file name.
89
After completion, the page will display all mounted ISO files.
You can click ―Unmount‖ to eliminate a mounted ISO file.
B. Using ISO
The mounted ISO file will be located in the share folder of the same name as the file.
Please refer the screen shot below. Here, the ISO file ―Thecus 01‖ wasn‘t assigned
a mounting name, so the system automatically created a folder ―Thecus 01‖.

like to expand and click the Expand button:
100
You will then see the dialog box displayed below. Drag the Expand Capacity bar to
the size you want. Then press Expand to confirm the operation.
NOTE
The iSCSI expand is only capable while iSCSI
target volume is crested by ―Instant Allocation‖.
iSCSI target created by ―Thin Provisioning‖ has
virtual space assigned during the initial stage, so it
has no expandable capability.
Delete Volume
To delete volume on the current RAID volume, follow the steps below:
1. Under the Volume Allocation List, click Delete.
The Space Allocation screen appears.
101
2. Press YES. All data in the volume will be removed.
iSCSI Thin-Provisioning
If iSCSI Thin-Provisioning is selected when creating an iSCSI target volume, virtual
memory is assigned to the target, allowing the physical memory to reach maximum
capacity and adding new disks only when needed.
To setup iSCSI thin-provisioning, simply select ―Thin-Provision‖ mode from the
―Create LUN‖ setting screen.
Next, allocate capacity for the iSCSI thin-provision volume by dragging the
Allocation bar to the desired size.
After the size has been determined, click OK to confirm. Now you will see the iSCSI
thin-provisioning volume is available from the list. Please refer to the screenshot
below.
102
If creating an iSCSI target volume under ―Instant Allocation‖, physical memory is
assign to the target, being limited by the available memory. For the iSCSI target
volume created under ―thin-provisioning‖, virtual memory is assigned to the
volume, which can go up to 16384GB (16TB).
LUN ACL
After iSCSI target has been created, you are one step away from using the iSCSI
volume. Under ―LUN ACL‖, you need to add ―Initiator iqn‖ and setup ACL access
privileges to determine the accessibility. Please refer the screen shot below for
where ―Initiator iqn‖ can be found.
From the LUN ACL setting screen click ―Add‖:
Next, input ―Initiator iqn‖ and setup iSCSI target volume access privileges from the
available list. Apply by clicking the OK button.
103
The accessible Initiator will be listed as shown in the screen shot displayed below.
The listed ―Initiator iqn‖ can be modified or deleted by selecting the desired iqn and
pressing Modify or Delete.
Advance Option
There are 3 available options for the user to operate Thecus IP storage associated
with iSCSI setting. The details are listed in the following screenshot. If the options
are modified, the system will need to reboot for the changes to take place.
104
iSCSI CRC/Checksum
To enable this option, the initiator can connect with ―Data digest‖ and ―Header
digest‖.
Max Connections
The maximum number of iSCSI connections.
Error Recovery Level
The Error Recovery Level (ERL) is negotiated during a leading iSCSI connection
login in traditional iSCSI (RFC 3720) and iSER (RFC 5046).
ERL=0: Session Recovery
ERL=0 (Session Recovery) is triggered when failures within a command,
within a connection, and/or within TCP occur. This causes all of the previous
connections from the failed session to be restarted on a new session by
sending a iSCSI Login Request with a zero TSIHRestart all iSCSI connections
on any failure.
ERL=1: Digest Failure Recovery
ERL=1, only applies to traditional iSCSI. For iSCSI/SCTP (which has its own
CRC32C) and both types of iSER (so far), handling header and data checksum
recovery can be disabled.
ERL=2: Connection Recovery
ERL=2, allows for both single and multiple communication path sessions
within a iSCSI Nexus (and hence the SCSI Nexus) to actively perform
realligence/retry on iSCSI ITTs from failed iSCSI connections. ERL=2 allows
iSCSI fabrics to take advantage of recovery in all regards of transport level
105
fabric failures, and in a completely OS independent fashion (i.e. below the host
OS storage stack).
High-Availability (N8900, N12000 series/N16000 series only)
HA keeps your data active on two separate systems, Thecus Supports
Active/Passive HA — provides a fully redundant instance of each node, which is only
brought online when its associated primary node fails.
HA setup procedure:
HA needs two identical Thecus systems (same models and same hard disk slot
installed) which are capable for high availability features. One needs to be setup as
―Primary‖ and the second unit as ―Secondary‖, both units‘ needs to have the RAID
volume build up prior installation.
WARNING
Please be notified that if the system has been
used as a standalone station before and
contained more than one RAID volume with
data inside, once it is used for HA, all of data
will be destroyed.
Let‘s see an example with two Thecus Units.
1st unit: Host name: PMA (172.16.66.25) with JBOD RAID volume. This unit will be
setup as the Primary server.
106
2nd unit: Host name: PMS (172.16.66.24) with JBOD RAID volume. This unit will be
setup as the Secondary server.
WARNING
The HDD capacity of HA Secondary server
must be equal or greater than the Primary
server or a warning message will appear.
Setting up the Primary unit for HA. Let’s use the Primary unit from our
example PMA (172.16.66.25):
i.
Login in to web UI of system 172.16.66.25. Then go to ―High Availability‖
HA configuration page under the Storage category.
107
ii.
Click on ―Enable‖ radio button, then the setting page will appear.
iii.
Choose the server role of the system, for this example, we will have this unit
as ‗Primary Server‖. So ―Primary Server‖ is checked.
iv.
Choose the ―Auto Failback‖ option, the default is disabled. For more details
about auto failback, please refer to the description below.
Auto Fail Back:
In legacy Heartbeat clusters, the auto failback option would
determine whether a resource would automatically fail back to
its "Active" node, or remain on whatever node is serving it until
that node fails, or an administrator intervenes. The possible
values for auto failback were:
on - enable automatic failbacks
off - disable automatic failback
When auto failback is off (default): After the original
active server is damaged and then returned to a healthy
state, the original standby server will remain active and
the original active server will go into standby mode. The
servers will exchange roles.
When auto failback is on: After the original active server is
damaged and then returned to a healthy state, the original
standby server will go back into standby mode and the
original active server will become active again. The
servers return to their original roles.
With or without auto failback, synchronization will begin
immediately without a break in service when the damaged
server returns. The roles described above are assumed
immediately and do not need to wait for synchronization.
The virtual IP will always be mapped to the current active

Fill in the ―Virtual Server‖ hostname information for further access need. For
this example, we will use ―HApm‖ for the virtual server hostname.
108
vi.
vii.
Fill in the ―Secondary Server‖ hostname information. For this example, we
will use ―PMS‖ for the secondary server hostname. Please make sure the
associated Secondary server with the ―PMS‖ host name has been setup.
Fill in the ―Virtual IP‖ information:
1. Please select the network interface from the drop down list of physical
connective available. It can be either on board LAN ports or additional
add-in NIC, even 10G.
2. Input ―Indicate‖ IP address. This ―indicate IP‖ is used for the system to
ping out then check whether the system is still alive. So please input an
IP address that is going to response properly.
3. Filled in IP information for the ―Virtual IP‖ and ―Secondary Server IP‖ in
either IPv4 or IPv6. For our example we chose the ―WAN/LAN1‖ for the
connection interface and virtual IP 172.16.66.87. The secondary server
IP address is 172.16.66.24 has mentioned earlier.
viii.
Choose the network interface for heartbeat in between the systems. It can
be selected from the drop down list, if there is additional LAN card that has
been installed, such as 10G card, it can be used for the heartbeat role.
After inserting the IP addresses for direct link needed in between the
primary and secondary servers, default value will appear. Normally, no
modifications will be required.
The example here we will use the ―Additional LAN4‖ which is a 10G NIC to be
used for the heartbeat link between the primary and secondary servers.

Advance options can be setup by pressing the associated button.
Heart Beats Configuration
Item
Description
Keep alive time
The keep alive directive sets the interval between heartbeat
packets. It is specified according to the Heartbeat time syntax.
Dead time
The dead ping directive is used to specify how quickly Heartbeat
should decide that a ping node in a cluster is dead. Setting this
value too low will cause the system to falsely declare the ping
node dead. Setting it too high will delay detection of
communication failure.
This feature has been replaced by the more flexible ping
resource agent in Pacemaker, and should no longer be used.
Warning time
The warn time directive is used to specify how quickly Heartbeat
should issue a "late heartbeat" warning.
Initial dead time
The initial dead parameter is used to set the time that it takes to
declare a cluster node dead when Heartbeat is first started. This
parameter generally needs to be set to a higher value, because
experience suggests that it sometimes takes operating systems
many seconds for their communication systems before they
operate correctly.
UDP port
The udp port directive specifies which port Heartbeat will use
for its UDP intra-cluster communication. The default value for
this parameter is UDP 694 port.

Click ―Apply‖, the Primary server will prompt the message below and wait
for the ―Standby‖ server settings to be completed.
Setting up the Secondary unit for HA. The secondary unit for our example
is PMS (172.16.66.24):
xi.
Login in to the web UI of the system 172.16.66.24 then go to ―High
Availability‖ HA configuration page under the Storage category.
xii.
Click on the ―Enable‖ radio button, the setting page will appear.
xiii.
Choose the server role of the system, for this example, we will have this unit
set as the ―Secondary Server‖. So ―Secondary Server‖ is checked. After,
please fill in the associated ―Primary Server‖ IP address.
xiv.
Click ―Detect‖ and the Secondary unit will start to check for the Primary
server status. If the Primary server has replied properly, then the message
will appear as below.
Please check the Primary Server unit. You will see an interactive message
saying to reboot both ―Primary‖ and ‗Secondary‖ server together to
complete the High Availability settings.
The last state of the Primary server is: waiting for the Secondary server as
shown in the screen shot below:
111
After the Secondary server has communicated with Primary Server
successfully, then the state will changed to:
Click ―Yes‖ to reboot both Primary and Secondary server.
If the communication has failed then you will see an error message as below.
Conditions in which the secondary server will take over to play the role as
Active:
1. Primary server RAID is damaged
2. Loss of the primary server‘s data port connection
3. Primary server goes down for any other reason
When the primary server encounters the above-mentioned situations, the
secondary server (PMS) will immediately take over to play the role as active. The
secondary server's system log will show "HA changed to active, getting resources",
and "Healthy: The RAID [HA] on system [PMS] is healthy now."
112
At this time, the virtual IP address will be mapped to the PMS system because it is
in an active state.
HA Ready:
After both Primary and Secondary systems has rebooted, the HA link status and the
HA RAID volume can be seen from the HA status page.
Please note, it will take 1~2 minutes to complete the primary and secondary
servers‘ role played. If both servers are displayed as standby, please wait for the
systems to synchronize with each other.
From the HA Primary server ―PMA (172.16.66.25)‖ it will denote the role of ―Active‖
and for the ―PMS (172.16.66.24)‖, it will show the role as Standby.
The HA RAID volume status can be found as shown in the screen shot below.
The user can access this newly create HA system by its virtual IP. Using widows, the
user can simply input 172.16.64.87 or HApm in the navigation bar then the
available share files will be listed as below:
113
HA Recovery:
If one of the HA member is down and need to be recovered, simply go to the RAID
management page and the ―HA Recovery‖ icon will be available.
Click on the ―HA Recovery‖ icon, then the system will prompt a box to inquire about
the Active server heartbeat link IP address. After inputting the IP address and
pressing Apply, the unit will be recovered fully.
Another circumstance where HA recovery might be needed is when the HA button
has been enable but the system detected a previously existing HA configuration.
Then the screen will prompt the message box as shown below:
114
If the other HA member is running smoothly, please choose ―Recovery HA‖ to
complete HA recovery. Or select ―No, continue‖ to let both HA members has they
are.
WARNING
WARNING
If there are transfers in progress when the
Primary server encounters problems and the
Secondary server becomes active, the session
will be stopped. Please contact your network
administrator to determine whether or not
your transfers were completed.
When the original primary server rejoins the
HA environment, it will be updated with the
newer data from the secondary server to
synchronize for HA. Please be aware that the
data on the original primary server will be
replaced by the data from the secondary
server.

address is changed, the NAS will notify the DDNS provider immediately to record
the new IP address. When the user tries to connect to the NAS by the host name,
the DDNS will transfer the recorded IP address to the user.

Backup
There are a number of ways to back up data with the Thecus IP storage.
Dual DOM (N12000 series/N16000 series/N8900 series only)
The unique Dual DOM feature can now perform ―Auto Repair‖. The Thecus NAS will
backup up to five versions of the system configuration either by the default timing
of 1:00am every day automatically or as scheduled by the user.
This unique ―Auto Repair‖ will be triggered if the primary DOM has a booting issue.
In this instance, the 2nd DOM will take over the boot function. Then, the system will
automatically load the most recent system configuration backup image to repair
the primary DOM.
135
Rsync Target Server
When it comes to backing up your data, it‘s very important to have flexibility. Data
guard provides you with many options, including full backup for all shares, custom
backup for selected shares and iSCSI volume backup. Being based on the Linux
operating system, it is also much more stable and experiences much less frequent
data loss during transfer than other remote backup systems.
-For this tutorial you will need to use Rsync Target Server (Step 1) and Data Guard
(Step 2+3) under Backup for this client/server backup feature. It also can be
named for function ―Remote Replication‖.
Step 1 – Enabling Rsync on your target (backup) NAS
-Log in to your target (backup) NAS through the UI in your web browser
-Go to Rsync Target Server under Backup in the menu of the UI
136
1. Enable Rsync Target Server
2. Add a username and password (they can be different than your NAS‘s
username and password)
3. Select Apply
NOTE
• You will need this user name and password while the data is going to
remotely backup to this Rsync target server.
• The Rsync target server is only allowed 3 Rsync hosts to connect and
backup from.
Now Rsync is turned on your NAS, which means it can be used as a target for Rsync
backup, in other words, only the backup NAS needs to be activated in this way.
Data Guard (Remote Backup)
Step 2 – Setting up your backup task and schedule on your source NAS
-Log in to your other NAS (your source NAS) through the UI in your web browser
-Go to Data Guard under Backup in the menu of the UI

This is how this task will appear in the task list.
Real time:
It will backup folders/files from source to target on the
fly. On the other hand, any changes from the source will
back up to the target right away.
Schedule:
The task will start only according to the schedule.
Sync mode:
Makes your source match your target completely;
deleting and adding files on your target as they are
deleted and added on your source.
Incremental Mode :
Makes your source match your target and keep all old
files; adding files on your target as they are added on your
source, but NOT deleting files on your target as they are
deleted on your source.
With this option, compress the file data as it is sent to the
destination machine, which reduces the amount of data
being transmitted – something that is useful over a slow
connection.
Enabling this will back up the source unit system
configurations to the designed path on the target system.
Try to handle sparse file efficiently so they take up less
space on the destination.
It will backup not just data itself but also ACL

After the required fields are filled and the parameters are setup, click ‗Finish‖ to
complete. The data guard task will appear in the list as shown below.
From the task list, you can now see the newly added task ―fullback01‖. The backup
is setup as ―real time‖. From the status field, ―Processing‖ can be read as the
back-up is performed on the fly.
Custom Backup
The custom backup setting is similar to the full backup. The only differences are
explained below:
1. Inputs the share folder name of target sever where the source is going to
backup. The sub-folder can be left as blank.
2. Select the source share folder(s) which are desired to be backed up to the target
141
server. You can also click on ―Select All‖ from top right corner check box.
3. Click ―Next‖ and more setting appears. These are the as the settings for ―Full
backup‖
4. Click ―Finish‖ and the data guard task will appear in the list as shown below.
142
From the task list, you can now see the newly added ―customback01‖. This backup
is setup as ―schedule‖.
iSCSI Backup
If the source unit contains iSCSI volume, it can be backed up to the target unit as
a single file. The procedure is the same as for the previous ―Full backup‖ and
―Custom backup‖, select ―iSCSI backup‖ from data guard wizard.
1. Inputs the share folder name of the target sever where the source is going to
backup. The sub-folder can be left as blank.
2. Select the iSCSI target volume which you wish to back up to the target server.
143
3. Click ―Next‖ and more settings will appear. It is slightly differing from ―Full
backup‖ and ―Custom backup‖. Only ―Schedule‖ backup is supported with less
options.
4. Click ―Finish‖ and the data guard task will appear in the list as shown below.
From the task list, you can now see the newly added ―iscsiback01‖. This backup is
setup as ―schedule‖.
144
NOTE
• The source folder name will use iSCSI_+target volume name. So here
it is displayed as ―iSCSI_pmtest‖. pmtest is the iSCSI target name
when the iSCSI target was created.
The iSCSI backup can see the result as below. The task ―iSCSI_pmtest‖ has backup
to target 172.16.66.111 and share folder NAS_Public with file ―iSCSI_pmtest‖.
Restore
To restore a backup from the backup task, simply select a task from the task list
then click ―Restore‖ from the function bar. The restore task will start to have the
associated files/folders from the target server restored to the source.
NOTE
• To restore task with backup type set as ―Real time‖, first you need to
stop the task then you can proceed with the restore operation.
Restore NAS Configuration
This is a useful feature if the system configuration needs to be restored to a brand
new unit. Let‘s go thru the following example to see how it works.
The original source system has 3 RAID volume, ―RAID‖, ‗RAID10‖ and ―RAID20‖,
and has backed up the system configurations to the target server.
145
The brand new source unit only has a 1 RAID volume ‗RAID‖.
1. When adding a new backup task with ―Full backup‖ or ―Custom backup‖ and
enabling the option ―Backup NAS Config‖ as shows below, the source unit
system configurations are then backed up to the designed path on the target
system every time the task is executed.
2. Click on ―Restore NAS Configuration‖ and the screen shown below will appear.
Input the target server‘s IP address where the system configuration has been
backed up, and necessary authentication info. Confirm by doing a ―Connection
Test‖ to make sure the communication between the source and the target
server works.
146
3. Click ―Next‖ and a screen will appear as shown below. It has the listed available
system configuration backup files. Select the one you want and click next. You
also have the option to download the current system configuration before
restoring from the backup file.
4. After clicking ―Next‖, a screen will appear as shown below. Listed on the left
hand side, you will see the configuration backup details which contain the 3
RAID volumes. On the right hand side, you will see a list of single ―RAID‖
volume. You may roll back to previous page to recall the example we have
taken.
5. The backup configuration has different numbers of RAID volume than the
current system (3 vs 1). It can be kept as the RAID volume mapping arranged
by the system, then carry on to click ―Finish‖. This means that all 3 RAID
volumes configuration such as share folder etc. will all restore to the current
unit in the RAID volume ―RAID‖.
6. In other circumstances, if the current unit contains 2 RAID volumes, then it can
be chosen from the left hand side of system backup configuration RAID volume
list which RAID volume to map to the current system.
Let‘s see the following screen to make it clearer.
147
The current system has 2 RAID volumes, ―RAID‖ and ―RAIDa‖. Select the RAID
volume from the backup configuration volume list which is going to be mapped
to the RAID volume of the current system. Simply click on the right hand side of
―RAIDa‖ and a drop down list will appear. Now you can choose which volume to
map with. In this case the ―RAID01‖ volume from the system backup
configuration will be mapped to the volume ―RAIDa‖ of the current unit. Once
again, it means all the shares that were created in the volume ―RAID01‖ will be
restored to volume ―RAIDa‖ of the current system.
ACL Backup and Restore
The ACL backup and restore feature enables the system ACL (Access Control List)
to be backed up on the RAID volume based to other location and restored if needed.
Let‘s look at the example bellow to see how it works.
We have one system with a RAID volume ―RAID‖, select ―Backup‖ to backup this
RAID volume‘s ACL to other location. The current RAID volume ―RAID‖ has share
folder as listed on right hand screen shot.
For the ACL restore, it can be restored in the same system or used in another unit.
For example, let‘s restore the ACL backup file to another unit. This unit has a RAID
volume ―RAIDpm‖ with share folders as listed on right hand screen shot.
148
After inputting the ACL backup file and clicking the ―Next‖ button, the system will
show another screen to list the matched folders in between the backup file and this
RAID volume. Just select the desired folders for the ACL restore.
NOTE
• The ACL backup will only back to share folder level; it does not apply
to its sub-layer.
• The ACL backup/restore can be used among ext3/ext4/XFS file
system. ZFS can only be used with other RAID volume with ZFS file
system created.
• If recursive has been checked during the ACL restoration, it will apply
to all of its sub-folders with the same permission.

Chapter 5: Tips and Tricks
USB and eSATA Storage Expansion
The Thecus IP storage supports external USB hard disks through its USB ports.
Once a USB hard disk is successfully mounted, the entire volume will be linked
automatically to the default USB HDD folder. The Thecus IP storage supports USB
external storage devices. All file names on the USB disk volume are case sensitive.
159
The Thecus IP storage also supports eSATA hard disks with its eSATA port.
Before attaching an eSATA or USB disk drive to Thecus IP storage, you have to
partition and format it on a desktop computer or a notebook first. The attached
device will be located at \\192.168.1.100\usbhdd\sd(x)1 where 192.168.1.100
means the IP address of Thecus IP storage and sd(x)1 stands for the first partition
on the eSATA or USB disk drive.
Remote Administration
You can set up your Thecus IP storage for remote administration. With remote
administration, you can access your Thecus IP storage over the Internet, even if
your Thecus IP storage is behind a router. This is especially useful if you are
traveling and suddenly need a file from your Thecus IP storage.
Setting up remote administration is a three-part process, and will require the
following equipment:


Replacing Damaged Hard Drives
If you are using RAID 1, RAID 5, RAID 6, RAID 50 or RAID 60 you can easily replace
a damaged hard drive in the Thecus IP storage while keeping your data secure with
the system‘s automatic data recovery.
Hard Drive Damage
When a hard drive is damaged and data in the RAID volume is corrupted, the
system OLED will display a warning message and the system will beep.
Replacing a Hard Drive
To replace a hard disk drive in the Thecus IP storage:
1. Remove the tray with the damaged hard disk.
2. Unscrew the damaged hard disk and remove it from the tray.
3. Slide a new hard disk into the tray and fasten the screws.
4. Insert the hard disk tray back into the Thecus IP storage until it snaps into
place. You can also lock it with a key if desired.
5. The LED will blink green when the HDD is accessed.
RAID Auto-Rebuild
When using RAID 1, 5, 6, 10, 50 or 60 on the Thecus IP storage, you can use the
auto-rebuild function when an error is detected.
1. When a hard disk fails the system beeps and/or an email notification is sent
to the specified receivers.
2. Check the OLED to see which disk has failed.
3. Follow the steps mentioned above to replace the failed hard disk.
4. The system automatically recognizes the new hard disk and starts the
auto-rebuild sequence to resume its status before the hard disk crash.
162
Chapter 6: Troubleshooting
Forgot My Network IP Address
If you forget your network IP address and have no physical access to the system,
you can find out the IP address by either looking directly onto the Thecus IP storage
OLED panel, or by using the setup wizard to retrieve the IP of your Thecus IP
storage.
1. Start the Setup Wizard, and it will automatically detect all Thecus IP storage
products on your network.
2. You should be able to find the IP address of the Thecus IP storage which you
have forgotten in the Device Discovery screen.
Can't Map a Network Drive in Windows XP
You may have problems mapping a network drive under the following conditions:
1. The network folder is currently mapped using a different user name and
password. To connect using a different user name and password, first
disconnect any existing mappings to this network share.
2. The mapped network drive could not be created because the following error
has occurred: Multiple connections to a server or shared resource by
the same user, using more than one user name, are not allowed.
Disconnect all previous connections to the server or shared resource and try
again.
To check out existing network connections, type net use under the DOS prompt.
You may refer the URL below for more network mapping information.

Restoring Factory Defaults
From the System menu, choose the Factory Default item and the Reset to
Factory Default screen appears. Press Apply to reset Thecus IP storage factory
default settings.
WARNING
Resetting to factory defaults will not erase the data stored in the hard
disks, but WILL revert all the settings to the factory default values.
163
Problems with Time and Date Settings
The administrator is able to select an NTP Server to keep Thecus IP storage time
synchronized. However, if Thecus IP storage cannot access the Internet, you may
encounter a problem when setting the Time and Time Zone. If this happens:
1. Login to the Web Administration Interface.
2. Navigate to System Management>Time.
3. Under NTP Server, select No.
4. Set the Date, Time, and Time Zone.
5. Click Apply.
In addition, if the Thecus IP storage is able to access the Internet and you want to
keep the NTP Server clock.isc.org by default, please make sure the DNS Server is
correctly entered, thereby allowing the NTP Server name to correctly resolve. (See
System Network > WAN/LAN1 > DNS Server)
Dual DOM Supports for Dual Protection (N12000
series/N16000 series/N8900 series only)
The most advance and useful feature on the Thecus IP storage (depend on models)
is the implemented Dual DOM. Under normal circumstances, there is no need to
have this feature involved. But some unpredictable problems like power cut or
human error can occur by accident, especially during system booting stage; the
Dual Dom will become the best feature to prevent system down time.
Practically while it happened, system will try to recover the DOM 1 from DOM 2 first.
If it is unachievable then the system can boot from DOM 2. And all of these
procedures can be operated through the OLED.
NOTE
The DOM1 in Dual DOM is by default the master DOM and FW updates will
only apply to DOM1. DOM2 is ‗Read only‖.
If anything happened and the DOM1 is recovered from DOM2, the FW
version will be the one of the DOM2. Therefore, it may need to be
upgraded to the version of DOM1.
If DOM1 can not be recovered from DOM2, the system will boot up from
DOM2. The original configuration of DOM1 may need to be setup again
with DOM2 operations.

shows total count of hours (or minutes, or seconds, depending on
manufacturer) in power-on state.
Temperature Celsius
The current temperature of the hard disk in degrees Celsius.
Reallocated Sector
Count of reallocated sectors. When the hard drive finds a
Count
read/write/verification error, it marks this sector as "reallocated"
167
Test Type
and transfers data to a special reserved area (spare area).
This process is also known as remapping and "reallocated"
sectors are called remaps. This is why, on a modern hard disks,
you cannot see "bad blocks" while testing the surface - all bad
blocks are hidden in reallocated sectors. However, the more
sectors that are reallocated, the more a decrease (up to 10% or
more) can be noticed in disk read/write speeds.
Current count of unstable sectors (waiting for remapping). The
raw value of this attribute indicates the total number of sectors
waiting for remapping. Later, when some of these sectors are
read successfully, the value is decreased. If errors still occur
when reading sectors, the hard drive will try to restore the data,
transfer it to the reserved disk area (spare area), and mark this
sector as remapped. If this attribute value remains at zero, it
indicates that the quality of the corresponding surface area is low.
Set short or long time to test.
Test Result
Test Time
Result of the test.
Total time of the test.
Current Pending
Sector
NOTE
If the Reallocated Sector Count > 32 or the Current Pending Sector of a hard
disk drive > 0 , the status of the disk will show ―Warning‖. This warning is only
used to alert the system administrator that there are bad sectors on the disk,
and they should replace those disks as soon as possible.
Bad Block Scan
On the Disk Information screen, select a disk then click on ―Detect Bad Block‖ to
perform bad block scan of the associated disk. The result is only for reference and
the system will not take any action from its results.
The bad block scan can be terminated by clicking on ―Stop Detect Bad Block‖.
For Thecus product (N8900/N12000/N16000 series) which support JBOD device,
the attached JBOD device and his associated disks will also list under the Disk
Information page. Please see below for a screen shot of a N8900 with a Thecus
D16000 attached and installed disks list on.

Appendix B: RAID Basics
Overview
A Redundant Array of Independent Disks (RAID) is an array of several hard disks
that provide data security and high performance. A RAID system accesses several
hard disks simultaneously, which improves I/O performance over a single hard disk.
Data security is enhanced by a RAID, since data loss due to a hard disk failure is
minimized by regenerating redundant data from the other RAID hard disks.
Benefits
RAID improves I/O performance, and increases data security through fault
tolerance and redundant data storage.
Improved Performance
RAID provides access to several hard disk drives simultaneously, which greatly
increases I/O performance.
Data Security
Hard disk drive failure unfortunately is a common occurrence. A RAID helps prevent
against the loss of data due to hard disk failure. A RAID offers additional hard disk
drives that can avert data loss from a hard disk drive failure. If a hard drive fails,
the RAID volume can regenerate data from the data and parity stored on its other
hard disk drives.
RAID Levels
The Thecus IP storage supports standard RAID levels 0, 1, 5, 6, 10, 50, 60 and JBOD.
You choose a RAID level when you create a system volume. The factors for
selecting a RAID level are:



Your requirements for performance
Your need for data security
Number of hard disk drives in the system, capacity of hard disk drives in the
system
The following is a description of each RAID level:
RAID 0
RAID 0 is best suited for applications that need high bandwidth but do not require
a high level of data security. The RAID 0 level provides the best performance of all
the RAID levels, but it does not provide data redundancy.
RAID 0 uses disk striping and breaking up data into blocks to write across all hard
drives in the volume. The system can then use multiple hard drives for faster read
and write. The stripe size parameter that was set when the RAID was created
determines the size of each block. No parity calculations complicate the write
operation.
RAID 1
RAID 1 mirrors all data from one hard disk drive to a second one hard disk drive,
thus providing complete data redundancy. However, the cost of data storage
capacity is doubled.
187
This is excellent for complete data security.
RAID 5
RAID 5 offers data security and it is best suited for networks that perform many
small I/O transactions at the same time, as well as applications that require data
security such as office automation and online customer service. Use it also for
applications with high read requests but low write requests.
RAID 5 includes disk striping at the byte level and parity information is written to
several hard disk drives. If a hard disk fails the system uses parity stored on each
of the other hard disks to recreate all missing information.
RAID 6
RAID 6 is essentially an extension of RAID level 5 which allows for additional fault
tolerance by using a second independent distributed parity scheme (dual parity)
Data is striped on a block level across a set of drives, just like in RAID 5, and a
second set of parity is calculated and written across all the drives; RAID 6 provides
for an extremely high data fault tolerance and can sustain two simultaneous drive
failures.
This is a perfect solution for mission critical applications.
RAID 10
RAID 10 is implemented as a striped array whose segments are RAID 1 arrays.
RAID 10 has the same fault tolerance as RAID level 1.
RAID 10 has the same overhead for fault-tolerance as mirroring alone. High I/O
rates are achieved by striping RAID 1 segments.
Under certain circumstances, RAID 10 array can sustain up to 2 simultaneous drive
failures
Excellent solution for applications that would have otherwise gone with RAID 1 but
need an additional performance boost.
RAID 50
A RAID 50 combines the straight block-level striping of RAID 0 with the distributed
parity of RAID 5. This is a RAID 0 array striped across RAID 5 elements. It requires
at least 6 drives.
RAID 60
A RAID 60 combines the straight block-level striping of RAID 0 with the distributed
double parity of RAID 6. That is, a RAID 0 array striped across RAID 6 elements. It
requires at least 8 disks.
JBOD
Although a concatenation of disks (also called JBOD, or "Just a Bunch of Disks") is
not one of the numbered RAID levels, it is a popular method for combining multiple
physical disk drives into a single virtual one. As the name implies, disks are merely
concatenated together, end to beginning, so they appear to be a single large disk.
As the data on JBOD is not protected, one drive failure could result total data loss.
188
Stripe Size
The length of the data segments being written across multiple hard disks. Data is
written in stripes across the multiple hard disks of a RAID. Since multiple disks are
accessed at the same time, disk striping enhances performance. The stripes can
vary in size.
Disk Usage
When all disks are of the same size, and used in RAID, Thecus IP storage disk usage
percentage is listed below:
RAID Level
Percentage Used
RAID 0
100%
RAID 1
1/n x 100%

Appendix D: Active Directory Basics
Overview
With Windows 2000, Microsoft introduced Active Directory (ADS), which is a large
database/information store. Prior to Active Directory the Windows OS could not
store additional information in its domain database. Active Directory also solved
the problem of locating resources; which previously relied on Network
Neighborhood, and was slow. Managing users and groups were among other issues
Active Directory solved.
What is Active Directory?
Active Directory was built as a scalable, extensible directory service that was
designed to meet corporate needs. A repository for storing user information,
accounts, passwords, printers, computers, network information and other data,
Microsoft calls Active Directory a "namespace" where names can be resolved.
ADS Benefits
ADS lets Thecus IP storage integrate itself with the existing ADS in an office
environment. This means the Thecus IP storage is able to recognize your office
users and passwords on the ADS server. Other major benefits ADS support
provides include:
1. Easy integration of Thecus IP storage into the existing office IT
infrastructure
The Thecus IP storage acts as a member of the ADS. This feature
significantly lowers the overhead of the system administrator. For example,
corporate security policies and user privileges on an ADS server can be
enforced automatically on Thecus IP storage.
2. Centralized user/password database
The Thecus IP storage does not maintain its own copy of the user/password
database. This avoids data inconsistency between Thecus IP storage and
other servers. For example, without ADS support, an administrator might
need to remove a specific user privilege on Thecus IP storage and each
individual server. With ADS support, the change on an ADS server is known
to all of its ADS members.

GNU General Public License
Version 2, June 1991
Copyright © 1989, 1991 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 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
194
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.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice
placed by the copyright holder saying it may be distributed under the terms of
this General Public License. The "Program", below, refers to any such program
or work, and a "work based on the Program" means either the Program or any
derivative work under copyright law: that is to say, a work containing the
Program or a portion of it, either verbatim or with modifications and/or
translated into another Language. (Hereinafter, translation is included
without limitation in the term "modification".) Each licensee is addressed as
"you".
Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered only if its contents
constitute a work based on the Program (independent of having been made by
running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's 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 give any other recipients of the Program a
copy of this License along with the Program.
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 Program or any portion of it, thus
forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating that
you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in
part contains or is derived from the Program or any part thereof, to be
licensed as a whole at no charge to all third parties under the terms of this
License.
c) If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the most
ordinary way, to print or display an announcement including an appropriate
195
copyright notice and a notice that there is no warranty (or else, saying that
you provide a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is interactive but does not normally print
such an announcement, your work based on the Program is not required to
print an announcement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, 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 Program, 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 Program.
In addition, mere aggregation of another work not based on the Program with
the Program (or with a work based on the Program) on a volume of a storage or
distribution medium does not bring the other work under the scope of this
License.
3. You may copy and distribute the Program (or a work based on it, under Section
2) in object code or executable form under the terms of Sections 1 and 2 above
provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source
code, which must be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any
third party, for a charge no more than your cost of physically performing source
distribution, a complete machine-readable copy of the corresponding source
code, to be distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for
noncommercial distribution and only if you received the program in object code
or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, 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 executable. However, as a special exception, the source code 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.
If distribution of executable or 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 counts as distribution of the source code, even
196
though third parties are not compelled to copy the source along with the object
code.
4. You may not copy, modify, sublicense, or distribute the Program except as
expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program 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.
5. 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
Program or its derivative works. These actions are prohibited by law if you do
not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this
License to do so, and all its terms and conditions for copying, distributing or
modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor to copy,
distribute or modify the Program 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 to this License.
7. 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 Program at all. For example, if a
patent license would not permit royalty-free redistribution of the Program 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 Program.
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.
8. If the distribution and/or use of the Program is restricted in certain countries
either by patents or by copyrighted interfaces, the original copyright holder who
places the Program under this License may add an explicit geographical
distribution limitation excluding those countries, so that distribution is
197
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.
9. The Free Software Foundation may publish revised and/or new versions of the
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 Program
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 Program does not specify a version number of this License, you may
choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, 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
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.
12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
