Overview of LUN Manager
LUN Manager provides the open-systems user with ways to define the LU paths for the logical units
(LUs). Each LU can be mapped for access from multiple ports, providing the necessary infrastructure to support alternative path failover, path load balancing and clustered systems. You can use LUN
Manager to reconfigure the LUs while the storage system is online, so that you can accommodate system configuration changes and optimize storage system performance.
Overview of LUN Security
LUN Security provides ways for you to protect mission-critical data in your storage system from unauthorized access, by preventing unauthorized open-systems hosts from either seeing or accessing the data on the secured LU.

“Configuring LUs for use by RAID manager”
Overview of LUN Manager operations
The Remote Web Console storage system can be connected to open-system server hosts of different platforms (for example, UNIX servers and PC servers). To configure a system that includes open-system hosts and a torage system, you must use LUN Manager to configure logical volumes and ports. Throughout this manual, logical volumes are sometimes referred to as logical devices
(or LDEVs).
One of the important tasks with logical volume configuration is to define I/O paths from hosts to logical volumes. If the paths are defined, the hosts can send commands and data to the logical volumes and also can receive data from the logical volumes.
After the system begins operating, you might need to modify the system configuration. For example, if hosts or disks are added, you will need to add I/O paths. Even when the system is operating, you can modify the system configuration with LUN Manager. You do not need to reboot the system when changing the system configuration.
Use LUN Manager to make various settings with logical volumes (LUs). The settings include the LU path settings. When you configure a system, you must define LU paths to allow the hosts to transfer data to and from the storage.
It is necessary to change to Modify mode in the main window to achieve various settings within
LUN Manager. When the background color of the icon on the right of the window is light yellow
, the window is in Modify mode. When the background color of the icon on the right of the window is gray , the window is in View mode. If you click the gray background icon when the Unlocked icon is displayed, the icon changes to the yellow background icon and the mode changes to Modify mode.
CAUTION: When you define the LU paths, do not use the RAID Managerand Remote Web
Console at the same time.
Overview of Fibre-channel operations
After open-system hosts and the storage system are physically connected by cables, hubs, etc., you must use LUN Manager to establish I/O paths between the hosts and the logical volumes. This defines which host is able to access which logical volume. Logical volumes that can be accessed by open-system hosts are referred to as logical units (LUs). The paths between the open-system hosts and the LUs are referred to as LU paths.
Before defining LU paths, you must classify server hosts by host groups. For example, if Linux hosts and Windows hosts are connected to the storage system, you must create one host group for the
Linux hosts and another host group for the Windows hosts. Then, you must register the host bus adapters of the Linux hosts in the Linux host group. You must also register the host bus adapters of the Windows hosts in the Windows host group.
Overview of LUN Manager operations 7
Any host group can only contain hosts that are connected to the same port, and cannot contain hosts that are connected to different ports. For example, if two Windows hosts are connected to the port 1A and three Windows hosts are connected to the port 1B, you cannot register all the five
Windows hosts in one host group. You must register the first two Windows hosts in one host group and then register the remaining three Windows hosts in another host group.
After server hosts are classified into host groups, you must associate host groups to logical volumes.
In Figure 1 , the host group hg-lnx is associated with three logical volumes (00:00:00, 00:00:01, and 00:00:02). LU paths are defined between the two hosts in the hg-lnx group and the three logical volumes.
Figure 1 LU Paths configuration in a fibre channel environment
Use LUN Manager to define paths between a single server host and multiple LUs. The figure shows that each of the two hosts in the host group hg-lnx is able to access the three LUs.
Use LUN Manager to define paths between multiple server hosts and a single LU. The figure shows that the LU identified by the LDKC:CU:LDEV number 00:00:00 is accessible from the two hosts that belong to the hg-lnx host group.
The figure also shows that the LUs associated with the hg-lnx host group are addressed by numbers
0000 to 0002. The address number of an LU is referred to as LUN (logical unit number). When
TrueCopy and other program products manipulate LUs, the programs use LUNs to specify the LUs to be manipulated.
You can add, change, and delete LU paths when the system is in operation. For example, if new disks or server hosts are added to your storage system, you can add new LU paths. If an existing
8 About LUN Manager operations
server host is to be replaced, you delete the LU paths that correspond to the host before replacing the host. You do not need to restart the system when you add, change and delete LU paths with
LUN Manager.
If a hardware failure (such as a CHA failure) occurs, there is a chance that some LU paths are disabled and some I/O operations are stopped. To avoid such a situation, the system administrator can define alternate LU paths; if one LU path fails, the alternate path takes over the host I/O.
NOTE:
•
In a fibre-channel environment, up to 2,048 LU paths can be defined for one host group and up to 2,048 LU paths can be defined for one port.
•
You cannot define an LU path to volumes reserved by Volume Migration. For more information on Volume Migration, contact the HP.
•
Up to 255 host groups can be created for one fibre-channel port.
•
You cannot define an LU path to journal volumes.
•
You cannot define an LU path to pool volumes.
•
You cannot define an LU path to system disk volumes.
•
You cannot define an LU path to quorum disk volumes.
Configuring LUN Security
To protect mission-critical data in your storage system from illegal access, you must apply security policies to logical volumes. Use LUN Manager to enable LUN security on ports to safeguard LUs from illegal access.
If a port as the External attribute, you cannot apply LUN security to the port.
If LUN security is enabled, host groups affect which host can access which LUs. Hosts can only access to LUs associated with the host group that the hosts belong to. The hosts cannot access to
LUs associated with the other host groups. For example, hosts in the “hp-ux” host group cannot access LUs associated with the “windows” host group. Also, hosts in the “windows” host group cannot access LUs associated with the “hp-ux” host group.
In
Figure 2 , LUN security is enabled on the port CL1-A. The two hosts in the hg-lnx host group can
only access the three LUs (00:00:00, 00:00:01, and 00:00:02). The two hosts in the hg-hpux host group can only access the two LUs (00:02:01 and 00:02:02). The two hosts in the hg-solar host group can only access the two LUs (00:01:05 and 00:01:06).
Figure 2 Enabling LUN Security
Configuring LUN Security 9
Usually, you do not need to disable LUN security on ports. If LUN security is disabled on a port, the connected hosts will only be able to access LUs associated with the host group 0 (zero), and will be unable to access LUs associated with any other host group.
Figure 3 Disabling LUN Security
The host group 0 is the only host group reserved for each port by default. If you use the LUN
Manager window to view a list of host groups in a port, the host group 0 usually appears at the top of the list and is indicated by the number “00”
For example, the host group 0 for the port 1A is named 1A-G00 by default. Note that you can change the name of the host group 0.
By default, LUN security is disabled on each port. When you configure your system, you must enable LUN security on each port to which hosts are connected.
For details on how to apply LUN security, see Using LUN Security.
Configuring LUs for use by RAID manager
System administrators can enter RAID manager commands from open-system hosts to perform
Continuous Access Synchronous and Business Copy operations on logical devices. For example, the administrators can enter RAID manager commands to create or split pairs. If you want to allow the administrators to use RAID manager commands, you must ensure that at least one logical device is used as a command device. A command device receives RAID manager commands entered from open-system hosts. When the administrator enters a RAID manager command from an open-system host, the RAID manager command is transferred via the command device to the target logical device.
If you want to protect a logical device from RAID manager commands, you must apply command device security to the logical device. If the command device security is applied to a logical device, the device is not affected by RAID manager commands even when commands are transferred via a RAID manager device to that device.
You cannot use the following devices as RAID manager devices:
•
Volumes that do not have Read/Write access attribute
•
Volumes reserved by Auto LUN
•
Volumes reserved by Auto LUN. For more information on Auto LUN, contact HP.
•
Continuous Access Syncronous volumes
•
Business Copy volumes
•
Virtual volumes for Snapshot

System requirements
In order to use LUN manager, you need:
•
XP24000/XP20000 Disk Array
•
A computer that runs Remote Web Console
•
A license key for the LUN Manager program product
To use LUN Manager, you must use the Remote Web Console computer to connect to the disk array. When you connected, the Remote Web Console program, which is a Java application, will be downloaded to the Remote Web Console computer. You can perform LUN Manager operations in the Remote Web Console window.
Configuring your Remote Web Console computer
LUN Manager operations require the Remote Web Console program, which is downloaded to your Remote Web Console computer. Your Remote Web Console computer must be connected to the XP24000/XP20000 disk arrays via LAN. Browser settings are also required on your Remote
Web Console computer. If you are able to use Remote Web Console, you must install the LUN
Manager program product using the license key on the Remote Web Console computer.
Enabling required software
For details on how to enable LUN Manager, see the Storage System User Guide.
Notes on using LUN Manager
If you attempt to apply many settings in the LUN Manager windows, the SVP might be unable to continue processing. It is recommended that up to approximately 1,000 settings be made. Note that many settings are likely to be made when alternate paths are defined, even though only two commands are required for defining alternate paths.
•
Do not remove LU paths when the hosts perform I/O processing.
•
Do not disable LUN security when the hosts perform I/O processing.

NOTE: If you are using 2 Gbps HBA and switch, set the transfer speed of the CHF port as 2 Gbps. If you are using 1 Gbps HBA and switch, set the transfer speed of the CHF port as 1 Gbps. If you are using 4 Gbps HBA and switch, set the transfer speed of the CHF port as 4 Gbps. If you are using 8 Gbps HBA and switch, set the transfer speed of the CHF port as 8 Gbps. However, the transfer speed of the CHF port cannot be set as 1 Gbps when the CHF is 8US. Therefore, 1 Gbps HBA and switch cannot be connected. If the Auto Negotiation setting is required, the linkup may become improper at server reboot. Check a channel lamp, and if it is blinking, remove and re-insert the cable to perform the signal synchronization and linkup.
When the transfer speed of the CHF port is set to Auto, the data might not be transferred at the maximum speed depending on the connected device. Confirm the transfer speed at the Host Speed displayed in the Port list when you start up the storage system, HBA or switch. When the transfer speed is not the maximum speed, select the maximum speed from the list on the right or remove and re-insert the cable.

Defining fibre channel LU paths
If you are configuring a fibre channel environment, do the following:
1.
Find worldwide names (WWNs) of host bus adapters connected to the fibre channel ports.
See Finding WWNs
.
2.
Create host groups. See Creating Host Groups.
3.
Group open-system hosts by host groups. See Registering Hosts in Host Groups.
4.
Associate host groups with LUs. See Defining LU paths by associating host groups to logical volumes.
Finding WWNs
If you are configuring a fibre channel environment, you must verify that the fibre adapters and the fibre-channel device drivers are installed on the open-system hosts. Next, you must also find the worldwide name (WWN) of the host bus adapter that is used in each open-system host. The WWN is a unique identifier for a host bus adapter in an open-system host, consisting of 16 hexadecimal digits.
This section describes how to find the WWN of a host. We recommend you make a record of
WWNs of the hosts in your system, because you will need to enter WWNs in LUN Manager dialog boxes to specify the hosts used in your system.
Finding WWN for Windows
To find the WWN in a Windows environment with an Emulex Mini-Port driver:
1.
Verify that the fibre adapters and the fibre-channel device drivers are installed.
2.
Log in to the Windows 2000 host with administrator access.
3.
Go to the LightPulse Utility to open the LightPulse Utility window. See
.

Finding WWN for AIX, IRIX, or Sequent
To find the WWN in an IBM AIX®, SGI Irix®, or Sequent® environment, use the fibre switch that is connected to the host. The method of finding the WWN of the connected server on each port using the fibre switch depends on the type of switch. For instructions on finding the WWN, refer to the manual of the corresponding switch.
Finding WWN for HP-UX®
To find the WWN in an HP-UX environment:
1.
Verify that the fibre adapters and the fibre channel device drivers are installed. (See
.)
2.
Log in to the HP-UX host with root access.
3.
At the command line prompt, type: /usr/sbin/ioscan –fnC lan
This lists the attached fibre channel devices and their names.
28 Performing LUN Manager operations
4.
Record the fibre channel device file name (for example, /dev/fcms0).
5.
Use the fcmsutil command along with the fibre channel device name to list the WWN for that fibre channel device.
For example, to list the WWN for the device with the device name /dev/fcms0, type:
/opt/fcms/bin/fcmsutil /dev/fcms0
When the A5158 fibre channel adapter is used, at the command line prompt enter
/usr/sbin/ioscan -fnC fc for the device name.
6.
Record the fibre channel device file name (for example, /dev/td0).
When the A5158 fibre channel adapter is used, you would list the WWN for the device with the device file name as follows:
/opt/fcms/bin/fcmsutil <device file name>
7.
Record the WWN and repeat the above steps for each fibre channel device that you want to use.
Figure 23 HP-UX Worldwide Name
Creating host groups
You can connect multiple server hosts of different platforms to one port of your storage system.
When configuring your system, you must group server hosts connected to the storage system by host groups. For example, if HP-UX hosts and Windows hosts are connected to a port, you must create one host group for HP-UX hosts and also create another host group for Windows hosts.
Next, you must register HP-UX hosts to the corresponding host group and also register Windows hosts to the other host group.
To create a host group:

Registering Hosts in Host Groups
To set LU paths, you must register hosts in host groups. For example, if HP-UX hosts and Widows hosts are connected to a port, you must register HP-UX hosts and Windows hosts separately in two different host groups.
When registering a host, you are requested to specify the WWN of the host bus adapter. If you are unsure of WWNs of your host bus adapters, see
.
When you register hosts in multiple host groups, you must set the security switch (LUN security) to
ON. When you set the security switch to ON, you must specify the WWN of the host bus adapter.
When registering a host, you can assign a nickname to the host bus adapter. If you assign a nickname, you will be able to easily identify each host bus adapter in the LUN Manager window.
Although WWNs are also used to identify each host bus adapter, the nickname that you assign will be more helpful because you can name host bus adapters after the host installation site or the host owners.
34 Performing LUN Manager operations
NOTE:
•
A nickname can consist of up to 32 ASCII characters (letters, numerals, and symbols). However, you cannot use the following characters for nicknames:
\ / : , ; * ? " < > |
•
You cannot use space characters for the first and the last characters in nicknames.
•
Nicknames are case-sensitive. For example, hp and HP are different nicknames.
To register hosts in a host group in a Fibre Channel environment:
1.
Start LUN Manager and display the LUN Manager window.
2.
If the desired host has ever been connected via a cable to another port in the storage system, take the following steps: a.
Locate the Port list in the upper-right corner of the WWN list. Use this list to select the port to which the desired host is connected.
b.
Select the desired host bus adapter from the WWN list. Next, select a host group from the tree and then click Add WWN.
If you are using Windows, you can drag the desired host bus adapter from the WWN list to the host group in the tree. To drag two or more host bus adapters, see the HP
StorageWorks XP24000/XP20000 Remote Web Console User Guide to learn how to drag multiple objects.
c.
To assign a nickname to the host bus adapter, enter the nickname in the Name box in the Add New WWN dialog box
(page 36) , and then click OK.
If two or more host bus adapters are selected, the Add New WWN dialog boxes
appear—one after another to let you assign a nickname to each of the selected
HBAs. If you do not need to assign nicknames to HBAs, you can select the option The remaining WWNs do not need names and then click OK. If this option is selected, the
Add New WWN dialog box
will not appear prompting you to assign nicknames.
If the desired host has never been connected via a cable to any port in the storage system, take the following steps: a.
In the tree, right-click the host group and then select Add New WWN from the pop-up menu. The Add New WWN dialog box
You cannot add WWNs to host groups for initiator ports.
b.
Right-click the arrow on the right of the WWN list, and then select the desired host bus adapter from the list. If the list does not include the desired host bus adapter, enter the desired WWN in the WWN list.
c.
If necessary, enter a nickname for the host bus adapter.
d.
Click OK to close the Add New WWN dialog box. If a message appears, click OK.
The specified WWN and nickname appear below the selected host group.
3.
Click Apply in the LUN Manager window.
A message appears and asks if you want to apply the setting to the storage system.
4.
Click the OK button to close the message.
The settings are applied to the storage system and the specified host is registered in the host group.

Figure 26 Add New WWN Dialog Box (When Registering a Host that Has Never been Connected to the Storage System)
NOTE: If the WWN list (located near the lower-left corner of the window) includes a host that you want to register, you can register the host by dragging the host from the WWN list to the desired host group in the tree.
Defining LU Paths by Associating Host Groups to Logical Volumes
Use LUN Manager to define LU paths by associating host groups with logical volumes. For example, if you associate a host group consisting of three hosts with logical volumes, LU paths are defined between the three hosts and the logical volumes.
NOTE: When you use a logical volume larger than 2 TB, whether the host can access a logical volume larger than 2 TB depends on the operating system of the host.
The following operating systems support a logical volume that is larger than 2 TB.
•
AIX 5.2 TL08 or later
•
AIX 5.3 TL04 or later
•
Windows Server 2003 SP1 or later
•

Overview
When configuring a Fibre Channel environment, you can use LUN Manager to set user authentication between ports of the storage system and hosts. In a Fibre Channel environment, the ports and hosts use Null DH-CHAP as the authentication method. This section provides an overview of user authentication.
NOTE: Throughout this manual, Null DH-CHAP is sometimes referred to as CHAP.
The operation of user authentication in a Fibre Channel environment involves the following three phases:
1.
A host group of the storage system authenticates a host that attempts to connect (authentication of hosts).
2.
The host authenticates the connection-target host group of the storage system (authentication of host groups).
CAUTION: Because the host bus adapters currently do not support this function, this authentication phase is unusable in the Fibre Channel environment.
3.
A target port of the storage system authenticates a Fibre Channel switch that attempts to connect (authentication of Fibre Channel switches).
The storage system performs user authentication by host groups. Therefore, the host groups and hosts need to have their own user information for performing user authentication.
When a host attempts to connect to the storage system, the authentication of hosts phase starts. In this phase, it is determined whether the host group requires authentication of the host. If the host group does not require authentication of the host, then the host will connect to the storage system without authentication. If the host group requires it, authentication will be performed for the host.
When the host is authenticated successfully, the processing goes on to the next phase.
After the authentication of the host succeeds, if the host requires user authentication for the host group that is the connection target, the authentication of host groups phase starts. In this phase, the host groups and hosts authenticate with each other, that is, mutual authentication. In the
authentication of host groups phase, if the host does not require user authentication for the host group, the host will connect to the storage system without authentication of the host group.
38 Performing LUN Manager operations
The following explains the settings required for user authentication. The settings for authentication of host groups are needed only when you want to perform mutual authentication.
•
Settings for authentication of hosts
â—¦ On the storage system:
Use LUN Manager to specify whether to perform authentication of hosts on each host group. On a host group that performs authentication, register user information (group name, user name, and secret) of the hosts that are allowed to connect to the host group.
A secret is a password used in CHAP authentication. When registering user information, you can also specify whether to enable or disable authentication on a host basis. For details on the settings, see
and
â—¦ On hosts:
Configure the operating system and Fibre Channel host bus adapter driver for authentication by host groups with CHAP. You need to specify the user name and secret of the host used for CHAP. For details, see the documentation for the operating system and Fibre Channel host bus adapter driver in your environment.
•
Settings for authentication of ports (required if performing mutual authentication)
â—¦ On the storage system:
Use LUN Manager to specify user information (user name and secret) of each host group.
â—¦ On hosts:
Configure the operating system and Fibre Channel host bus adapter driver for authenticating host groups with CHAP. You need to specify the user name and secret of the host group that is the connection target. For details, see the documentation for the operating system and Fibre Channel host bus adapter driver in your environment.
When authentication of a host succeeds, the host performs authentication of the port reversely if required by the host (mutual authentication). In authentication of ports, when the user information
(user name and secret) of the port specified on the port side matches that stored on the host, the host allows the host group to connect.
Host and Host Group Authentication
When a host attempts to connect to the storage system, the connection results of the authentication of the host differs depending on the host group settings.

Each case in the flow is explained as follows. Case A to Case D in
corresponds that below.
•
When performing authentication of host groups
â—¦ If the user information for the host is registered on the host group, and authentication of the host is enabled (Case A):
The host group authenticates the user information sent from the host. If the authentication of the host successes, either of the following actions occur:
– When the host is configured for mutual authentication, the processing will go on to authentication of the host group, next.
– When the host is not configured for mutual authentication, the host will connect to the storage system.
40 Performing LUN Manager operations
If the host is not configured for authentication by host groups with CHAP, the authentication fails and the host cannot connect to the storage system.
â—¦ If the user information for the host is registered on the host group, but authentication of the host is disabled (Case B):
The host group does not perform authentication of the host. The host will connect to the storage system without authentication, regardless of whether or not the host is configured for authentication by host groups with CHAP.
â—¦ If the user information for the host is not registered on the host group (Case C):
Irrespective of the setting on the host, the host group performs authentication of the host, but results in failure. The host cannot connect to the storage system.
•
When connecting via a host group that does not perform authentication of hosts (Case D):
The host will connect to the storage system without authentication of the host, regardless of whether or not the host is configured for authentication by host groups with CHAP.
In this case, you need not register the user information for the host on the host group, but you can register it.
Notes: You should register user information for all hosts to be connected to a host group that performs authentication of hosts. To allow a specific host to connect to such a host group without authentication, configure the host group and the host as follows:
On the host group: Register the user information for the host you want to allow to connect without authentication, and then, disable the authentication setting of the host.

, host group 1 performs authentication of hosts, but host group 2 does not.
The user information for Host A is registered on host group 1, and the authentication setting is enabled. Therefore, if authentication of the host is successful, Host A can connect to the storage system (or, the processing goes on to the authentication of the host group). As a precondition of successful authentication, Host A should be configured for authentication by host groups with
CHAP.
The user information for Host B is also registered on host group 1, but the authentication setting is disabled. Therefore, Host B can connect to the storage system without authentication.
The user information for Host C is not registered on host group 1. Therefore, when Host C tries to connect to the storage system, the authentication fails and the connection request is denied, regardless of the setting on Host C.
Host D is attached to host group 2, which does not perform authentication of hosts. Therefore, Host
D can connect to the storage system without authentication.
During authentication of hosts, the connection result is determined by the combination of the following host group settings:

Setting the Fibre Channel Topology
The term topology indicates how devices are connected to each other. Fibre Channel provides the following types of topology:
•
Fabric: Utilizes a fabric switch to connect a large number of devices (up to 16 million) together.
Each device will have the full bandwidth of 100 MB/sec.
•
FC-AL (Fibre Channel-Arbitrated Loop): Shared interface that can connect up to 126 devices
(AL-ports) together. The 100 MB/sec bandwidth is shared among the devices connected to each other.
•
Point-to-point: The simplest fibre topology connects two devices directly together.
Figure 42 FC-AL Topology and Point-to-point Topology
When you configure your system, you must use the LUN Manager window to specify whether the hosts and the storage system are connected via a fabric switch.
If a fabric switch is used, specify FC-AL or point-to-point in the LUN Manager window (by default,
FC-AL is specified). If a fabric switch is used, consult the documentation for the fabric switch to learn whether FC-AL or point-to-point should be used. Some fabric switches require you to specify point-to-point to get the system running.
If no fabric switch is used, you must specify FC-AL.
To specify the topology:
1.
Start LUN Manager and display the Port window.
2.
In the Package tree, select the Fibre folder or a channel adapter of Fibre Channel.
•
If you select the Fibre folder, the Port list displays a list of Fibre Channel ports in the storage system.

NOTE: If a fabric switch is used, consult the documentation for the fabric switch to check if your fabric switch requires the point-to-point topology. Some fabric switches require the point-to-point topology to get the system running. To specify point-to-point topology, select
P-to-P.

CAUTION: When you change the settings while you are online to the hosts, the device may not be recognized from the hosts. In this case, you will need to reboot the hosts.
Changing the Fiber PCB Mode Between Standard, High Speed, and Initiator/External
Mix Mode
Channel adapter boards have built-in ports to be used for connecting hosts and a storage system.
The ports can be in Standard mode, High Speed mode, or Initiator/External MIX mode, though all the ports are in Standard mode by default. If a port satisfies certain conditions, you can apply
High Speed mode to the port to improve port performance. Or, if a port satisfies certain conditions, you can apply Initiator/External MIX mode so that one port can be used as both an initiator port for XP Continuous Access or XP Continuous Access Journal and an external port applied to a remote command device. For more information on how to define the remote command device, see the HP
StorageWorks XP24000/XP20000 External Storage Software User Guide.
You must apply High Speed mode or Initiator/External MIX mode to groups of four ports, not to individual ports. In LUN Manager terminology, each group of four ports is referred to as a port
block. You can apply High Speed mode or Initiator/External MIX mode to each port block.
When you apply High Speed mode or Initiator/External MIX mode, each pair of ports in a port block must satisfy the following conditions.
•
The two ports take the same fabric option (Enable or Disable).
•
The two ports take FC-AL as the Connection option.
•
The two ports use different port addresses and no matching addresses.
•
When you apply High Speed mode, the two ports take the same port attribute (the attribute can be Initiator, RCU target, or Target).
•
When you apply Initiator/External MIX mode, one port takes the Initiator attribute and the other port takes the External attribute.
•
Only one port is to be used for connecting the host.
shows an example of High Speed mode or Initiator/External MIX mode applied to one or two port blocks when the channel adapter board has 8 ports.
Configuring Fibre Channel Ports 63
Figure 43 Ports in High Speed Mode or Initiator/External MIX mode
If High Speed mode is applied to the four ports in a port block, only two of the ports can be used for connecting the host. When hosts issue I/Os to ports, the I/Os will be processed by processors on channel adapters. I/Os to each port will be processed by only one processor in Standard mode, but by two processors in High Speed mode. Therefore, ports in High Speed mode can process I/Os faster than ports in Standard mode. By balancing the workloads on the processors, a greater improvement can be expected with the system performance.
You cannot change standard mode to high-speed mode or vice versa while you are online to the hosts. You will need to reboot the hosts after changing the mode.
To change the configuration of a port that is being used, you must perform a backup operation before changing the port configuration.
Port names can differ, depending on whether ports are in Standard mode, High Speed mode, or
Initiator/External MIX mode. For detailed information about port names, see tables later in this section.
64 Performing LUN Manager operations
To improve the I/O processing speed by applying High Speed mode, a path definition is also necessary for a port that cannot be used for the connection with a host. For example, if the mode of the port block including the CL1-A port is changed to High Speed, the path definition is also necessary for the CL3-A [1-A 2nd] port that cannot be used for the connection with a host.
NOTE:
•
Sometimes the Standard mode, the High Speed mode, and the Initiator/External MIX mode are collectively referred to as Fibre PCB modes. PCB is an acronym for printed circuit board.
The storage system documentation sometimes uses the term PCB when referring to a channel adapter, which is a printed circuit board used for connecting hosts and a storage system.
•
Storage partition administrators cannot apply the High Speed mode or the Initiator/External
MIX mode.

Deleting LU Paths 75
Figure 45 Information about LU Paths to be Deleted
NOTE: If you delete numerous paths at one time, the deletion may take time and the dialog box may seem to hang temporarily.
Defining and Viewing Alternate Paths
LUN Manager enables you to define alternate paths. If one LU path fails, you can switch to its alternate path.
To create an alternate path, you need to copy the original path from one port to another. For example, if you want to define an alternative for the LU path from the CL1-A port to the logical volume 00:00 :01, you need to copy the LU path from the CL1-A port to another port.
Copying Paths between Fibre Channel Ports
To use alternate paths, you must copy LU paths from one port to another.
CAUTION:
•
Before taking the following steps, see
“Notes on using LUN Manager” (page 11)
for important information.
•
To define alternate paths when LUN security is disabled, you must redefine the LU path.
To define alternate paths:
1.
Start LUN Manager and display the LUN Manager window.
2.
In the tree, double-click the copy source port to display host groups below the port.

NOTE: The Group ID column indicates group numbers (G-IDs) of the host group.
Using LUN Security
To protect mission-critical data in your storage system from illegal access, you need to secure the logical volumes in the storage system. Use LUN Manager to secure LUs from illegal access by enabling LUN security on ports.
By default, LUN security is disabled on each port. When configuring your system, you must enable
LUN security on ports.
If a port has the External attribute, you cannot apply LUN security to the port.
When you register hosts in multiple host groups, you must set the security switch (LUN security) to
ON. When you set the security switch to ON, you must specify the WWN of the host bus adapter.
Enabling LUN Security
NOTE: If a port has the External attribute, you cannot apply LUN security to the port.
To enable LUN security on a port:
1.
Start LUN Manager and display the LUN Manager window.
2.
In the tree, locate the desired port.
3.
See the text on the right of the port name to find LUN security status:
•
If LUN security is enabled, you do not need to go through the remaining steps in this procedure.
•
If LUN security is disabled, go to the next step.
4.
Select and right-click the port.
5.
Select LUN Security: Disable -> Enable from the pop-up menu.
A message appears, asking if you want to change the LUN security setting.

Configuring the Storage System for Using RAID Manager
The system administrator can enter RAID Manager commands from open-system hosts to perform
XP Continuous Access and/or XP Business Copy operations on logical devices. For example, RAID
Manager commands can be used to create and split pairs. To enable the system administrator to enter RAID Manager commands from open-system hosts, you must specify at least one logical device as the command device. You can also apply command device security to other logical devices in the storage system.
NOTE: If a storage system is divided into SLPRs, and you want to prevent RAID Manager commands from affecting multiple SLPRs, you must apply command device security to the logical volumes.
Specifying Logical Devices as Command Devices
To enable the system administrator to execute RAID Manager commands from an open-system host, you must select at least one logical device that will not be manipulated by XP Continuous
Access or XP Business Copy, and then specify the device as the command device. When an RAID
Manager command is issued from a host, the command is received by the command device. The command device transfers the command to another logical device. Then, the command performs an XP Continuous Access or XP Business Copy operation on that logical device.
To specify a logical device as a command device:

). The following rules apply to UUIDs:
â—¦ The following characters cannot be used for UUIDs:
\ / : , ; * ? " < > |
â—¦ A space character cannot be used for the first and the last characters of a UUID.
â—¦ UUIDs are case-sensitive. For example, hp and HP are different UUIDs.
NOTE: Definition informations about devices set by LUN Manager are very important information to configure the system (for example, LUNs, LDKC:CU:LDEV, or UUID). HP recommends that you to make a correspondence table such as

Spreadsheet Declaration
The spreadsheet declaration is required, and is written at the beginning of the spreadsheet. Certain parts of the declaration will have already been written in the exported current spreadsheet. If the declaration line is incorrect, an error occurs and the spreadsheet file will be rejected.
NOTE: The spreadsheet declaration line is not case-sensitive.
•

Indicates the required process mode. The only mode that is currently available is Change, which indicates adding, changing, or deleting. When the downloaded spreadsheet file is opened, the process mode is not yet stated.
Function Tags
Before you write the settings, you need to state the function of the parameter. This is called a function tag, which is formatted as a string in brackets ([ ]). The type and order of the function tag are determined by the program product. Function tags have the following characteristics:
•
At least one function tag is required in a spreadsheet.
•
The function tag must be written at the very beginning of the row.
•
If a function tag is already on the current spreadsheet and does not need to be changed, it must be deleted from the new spreadsheet so it is not processed. If the function tag remains in the spreadsheet, and no new settings for the tag are written, the settings are processed as deleted. [CHA], [Port] and [LDEV] tags do not support a delete operation, so if no new setting is written for these functions an error occurs.
•
Any other comments and settings written in the same row as the function tag are ignored.
Spreadsheet Components 87
•
The row after the function tag indicates the required setting items (Cha and PcbMode in the example) for the function. The setting items are separated by commas.
â—¦ Example:
[Cha]
#Cha, PcbMode
•
The existing settings for the function are written. The existing settings row, which starts with
#$, is recognized as a comment row.
CAUTION: The settings in the rows that start with #$ are not allowed to change.
â—¦ Example:
[LUN]
#Port, Group Id, LunId, Ldkc, Cu, Ldev (items to be changed)
#$1C,0,1,1,1,1 (existing settings row)
•
An example of the declaration and the function tag is as follows.
#!Version 05_00_00,LUN,Change
[Cha]
[Port]
[HostGroup]
[WWN]
[LUN]
[LDEV]
As a general rule , the settings are applied to the storage system one at a time, in the order they appear in the spreadsheet. This means that the settings of the prior function tags can affect the following function tags. For example, if you were to delete a host group in the [HostGroup] tag, the path settings related to the deleted host group would also be automatically deleted. If you then write the new settings for the automatically deleted path in the [LUN] tag or the [WWN] tag, an error would occur.
Configuration Definitions
There are three types of configuration definitions: adding new settings, deleting current settings, and changing current settings.
•
Adding new settings. You can add new settings if the current settings area of the spreadsheet is blank (see
•
Deleting current settings. You can delete existing current settings by making the new settings area blank.
•
Changing current settings. You can change existing current settings by writing a different setting in the new settings area. The format of the existing setting and the new settings must be the same
The configuration definition consists of the index and the parameter (see
). The index is fixed for each function tag, so it must be the same for both the current settings and the new settings.
By modifying the settings in the parameter, you can add, delete, or change the settings.
You can write the configuration definition either between a function tag and another function tag, or between a function tag and the end of the file. Using a configuration definition, you can set the parameters (adding, deleting, or changing) for the storage system. A row of configuration definitions can be divided into the current settings area, a blank column, and the new settings area.
88 Performing LUN Manager Operations Using Configuration File Loader
Configuration definition settings must comply with the following:
•
The current settings area and the new settings area must be in exactly the same format, with three blank columns in between.
•
The maximum number of columns for the settings depends on the program product, and is stated in the declaration row.
•
The number of the available columns for each function tag depends on the number of parameters that can be set for each function and on the version of the spreadsheet.
•
When the current spreadsheet file is downloaded, the new settings area is left blank. All of the columns should be separated by commas.
•
You may not change the indexes, and all of the specified index settings indexes must match the actual settings.
•
Do not write the identical index more than once in the same function tag.
•
To change some, but not all, of the settings on the same configuration definitions, you must copy and paste the settings that you do not want to change to the new settings area. Otherwise, those settings will be processed as deleted.

Comments
You can also type comment rows in the spreadsheet by beginning a row with the # character. The comment row can consist of any characters in any language. A row that includes only a linefeed code is also recognized as a comment row.
•
Example:
# (comment)
# Change CHA settings (comment)
[Cha] (function tag)
# Cha, PcbMode (comment)
# (linefeed)
# (linefeed)

LUN Manager Spreadsheet Settings
The following LUN Manager functions can be defined by using Configuration File Loader:
•
Channel Adapter (CHA) settings allow you to change the PCB mode. See
.
•
Port Settings allow you to change the settings for arbitrated loop-physical address (AL-PA), data transfer speed (host speed), and topology. You can also change the LUN Security setting.
See
.
•
Host Group Settings allow you to create, delete, or change the host group. See
•
WWN settings allow you to add, delete or change the WWN information. See
•
LU path settings allow you to add, delete, or change LU paths. See
•
Command Device settings and set or release the command device and command device security. See
Column Format
Use a LUN Manager spreadsheet to write the settings for the CHA mode, port, host group, WWN, path definition, and command devices. The format of the LUN Manager spreadsheet is as follows:
•
1st column to 7th column: Current settings area
•
8th column to 10th column: Blank columns
•
11th column to 17th column: New settings area
The number of columns used depends on the function tag. If a particular function tag requires less than seven columns, the unused columns are left blank.

Configuring the Command Devices
Use the [LDEV] tag to change the command device settings. You cannot add or delete command device settings with the [LDEV] tag definitions.
When the command device (Cmd .Dev) is OFF, and the command device security (Cmd. Sec) is
ON, an error occurs.
You can set the command device OFF, regardless of the existence of the LU path.
When you want to configure the setting of a remote command device, add #$ at the beginning of the row. If you do not add #$, an error occurs.
You can save a file that contains LDEV information in the comma-separated value (CSV) format by using the Export button on the LDEV window of the Reports Display dialog box. You can set the command device by using this file. However, because the output form is different from the form of the configuration definitions, colons (:) that delimit the LDKC number, CU image number, and logical volume number have to be converted to commas (,). Use this information after you use commas to separate the LDEV index into three columns and when you use the spreadsheet software.

Error Check
First Error Check
The first error check is performed when the spreadsheet file is imported. The first error check verifies that the spreadsheet is properly formatted. If there is an error, the spreadsheet is rejected, and an error message is displayed. Errors detected at this first check include the following:
•
The first row of the spreadsheet (the declaration line) is not correctly written, or the stated program product is not installed. For more information on the declaration line, see
.
•
The spreadsheet file is not in text file format (the file is a binary file).
•
There is no function tag in the spreadsheet. For more information on the function tag, see
.
•
The file name is incorrect (for example, the extension is not .spd, or the file name exceeds the maximum number of letters).
•
The number of letters in a row exceeds 200.
•
The number of rows in a spreadsheet exceeds 400,000.
Second Error Check
In the second check, the spreadsheet settings are verified. Any errors found are displayed on the
Error Information list. This second check is performed before the Apply button becomes available.
shows the flow of the second check.
The second error check consists of two different types of the checks. These checks are shown in
as the Level 1 and Level 2. The Level 2 check is performed only when no error is found by the Level 1 check. Each level of the check of the second error check detects the following errors:
•
Level 1 check (the format and parameters are checked):
â—¦ A function tag is not supported.
â—¦ A setting value is incorrect or omitted.
â—¦ The setting range is incorrect. The correct ranges are as follows:
LDKC:00
CU:00 - FE
Error Check 97
LDEV:00 - FF
LUN: 0000 - 07FF
Group ID: 00 - FE
Host Mode: 00 - 4F
•
Level 2 check:
The current settings are compared to the imported settings and checked for logical consistency.
Note that certain errors can only be detected by the third check.
When you import a spreadsheet with no errors detected, the window displays Ready above the error information list, and the Apply button becomes available.
Figure 55 Second Error Check Flow Chart
Third Error Check
The third check is performed after the Apply button is selected. Errors detected at this third check include the following:
•
There is no difference between the current configuration definition and the configuration definition on the imported spreadsheet. The spreadsheet is accepted, but no operation will be performed.
•
You are trying to delete a LUN that is needed to process input/output (I/Os).
The errors caused by other factors are detected by the second check as the logical errors of the settings. However, there could be a case where the current settings are changed even though you are on the Modify mode. In this case, an error occurs at the third check.
If no errors are found on the third error check, the settings in the spreadsheet are applied to the storage system.

10
) bytes
•
1 MB (megabyte) = 1,024 or 1,024
2 bytes
•
1 GB (gigabyte) = 1,024 or 1,024
3 bytes
•
