About this Guide
1 Overview of HP StorageWorks XP LUN Manager Operations Overview of LUN Manager LUN Manager enables the open-systems user to define the paths for 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.
Overview of HP StorageWorks XP LUN Manager Operations
2 About LUN Manager Operations The HP 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 storage system, you must use LUN Manager to configure logical volumes and ports. One of the important tasks with logical volume configuration is to define I/O paths from hosts to logical volumes.
After server hosts are classified into host groups, you must associate host groups to logical volumes. In Figure 1 on page 16, 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.
If a hardware failure (such as a CHA failure) occurs, there is a chance that some LU paths will be disabled and some I/O operations 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. For instructions on how to define LU paths, see “Defining Fibre Channel LU Paths” on page 33. For instruc tions on how to change LU path settings, see “Changing the Fibre Channel LU Path Settings” on page 59.
Figure 3 Disabling LUN Security 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, host group 0 usually appears at the top of the list and is indicated by the number 00 (see Figure 1 on page 16). Note: By default, the name of host group 0 consists of the port name, a hyphen, and the number 00. For example, host group 0 for port 1A is named 1A-G00 by default. Note that you can change the name of host group 0.
3 Preparing for LUN Manager Operations System Requirements To use LUN Manager, you need: • the storage system • a computer that runs Remote Web Console (Remote Web Console computer ) • 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 storage system. When you connect, the Remote Web Console program, which is a Java application, will be downloaded to the Remote Web Console computer.
Preparing for LUN Manager Operations
4 Using the LUN Manager GUI Fibre Channel Windows LUN Manager Window When you launch LUN Manager, the LUN Manager window appears. The LUN Manager window lets you define LU paths and apply LUN security to logical volumes. Note: The storage partition administrators can display information or perform the operation within only the allocated SLPR (Storage Management Logical Partition). For the details on SLPRs, see the HP StorageWorks XP24000 Disk/Cache Partition User’s Guide.
The Fibre folder: If you double-click the Fibre folder, Fibre Channel ports in the storage system appear as icons. On the right side of each icon is the port name, the port address, LUN security status, and the port attribute (that is, whether the port is an initiator port, a target port, an RCU target port, or an external port). Note: The Fibre folder does not display if the storage system does not contain a Fibre Channel adapter.
Figure 6 The LU Path List Displays LUNs assigned to logical volumes. LUNs (logical unit numbers) are address numbers assigned to logical units (LUs), which are logical volumes that can be accessed by open-system hosts. If no paths are defined, the other columns on the right are left blank. LUN The icon indicates a logical volume to which an LU path is defined. The icon indicates an expanded LU. The icon indicates a command device. The icon indicates command device security.
• The Add WWN button registers host bus adapters in a host group. Before using this button, you must select a host group in the LU Path tree and also select host bus adapters (WWNs) in the WWN list. • The Add LU Path button defines LU paths to logical volumes. Before using this button, you must select LUNs in the LU Path list and also select logical volumes in the LDEV list. The WWN List In the lower left of the LUN Manager window is a list named WWN.
Figure 8 The LDEV List LDKC Displays the LDKC number 00. This number is grayed out. CU Lists CU images. Indicates logical volumes. This displays the LDKC number, the CU image number, and the LDEV number of a logical volume. These numbers are delimited by colon (:). LDKC:CU:LDEV The icon indicates a normal logical volume. The icon indicates an expanded LU (that is, a LUSE volume). The icon indicates a command device. The icon indicates command device security. indicates a remote command device.
Port Window When you launch LUN Manager and click the Port tab, the Port window appears. This window lets you make settings for Fibre Channel ports. Note: Storage partition administrators can display ports or perform the operation within only the allocated SLPR. For details on SLPRs, see the HP StorageWorks XP24000 Disk/Cache Partition User’s Guide. Figure 9 The Port Window (When Selecting Icon under Fibre Folder) Package Tree Use this tree to select the port to be operated.
Port List The Port list displays all ports on a channel adapter if you select a channel adapter in the Package tree. The Port list displays all ports in a port block if you select a port block. You can use the options in the Change Port Mode group box to change information in this list. Figure 10 The Port List Displaying Information about Fibre Channel Ports Port Name Displays port names. For details, see Table 7 on page 69 through Table 8 on page 73. Type Displays types of ports.
Figure 11 The Change Port Mode Box Displaying Information about Fibre Channel Ports Select a Port To change settings for a port, select the port from this drop-down list. Host Speed The text box on the left displays the data transfer speed for the selected port. The drop-down list on the right lets you specify the data transfer speed for the selected port. If Auto is selected, the storage system automatically sets the data transfer speed to 1 Gbps or 2 Gbps. Gbps is the acronym for Gigabits per second.
Figure 12 The Authentication Window (When Selecting Fibre Folder) Port Tree Use this tree to find information about user authentication on each port. If you double-click the Fibre folder, Fibre Channel ports in the storage system appear as icons. If you select the Fibre folder, information about ports and Fibre Channel switches is displayed to the right of the tree. Notes: The Fibre folder is displayed only if the storage system contains an Fibre Channel adapter.
Port Information List Port Name Displays Fibre Channel port names. For details, see Table 7 on page 69 through Table 8 on page 73. Time out Displays period of time between authentication sessions to a same port. If the previous authentication session to a port failed, the next authentication session starts after the specified period of time elapses. The unit is seconds. Refusal Intvl. If authentication fails for the number of times specified in Refusal Freq., connection to the port fails. Refusal Intvl.
Figure 14 The Authentication Window (When Selecting Port Icon under Fibre Folder) Port Tree Use this tree to find information about user authentication on each port. When you select a port from this tree, the Authentication Information (Target) list on the right displays user information for hosts registered on the port. In addition, the Authentication Information (Host) list displays the user information for the selected port.

Finding WWN for Windows NT or Windows 2000 HP currently supports the Emulex Fibre Channel adapter in a Windows NT or Windows 2000 environment, and will support other adapters in the future. For further information on Fibre Channel adapter support, or if you are using a Fibre Channel adapter other than Emulex, contact HP technical support for instructions on finding the WWN.
Figure 16 LightPulse Utility/NT Window Finding WWN for HP-UX To find the WWN in an HP-UX environment (see Figure 17 on page 36): 1. Verify that the fibre adapters and the Fibre Channel device drivers are installed. 2. Log in to the HP-UX host with root access. 3. At the command line prompt, type: /usr/sbin/ioscan -fnC lan 4. This will list the attached Fibre Channel devices and their device file names. Record the Fibre Channel device file name (for example, /dev/fcms0). 5.
Figure 17 HP-UX Worldwide Name Finding WWN for Solaris HP currently supports the JNI Fibre Channel adapter in a Sun Solaris environment. This document will be updated as needed to cover future adapter-specific information as those adapters are supported. For further information on Fibre Channel adapter support, or if you are using a Fibre Channel adapter other than JNI, contact HP technical support for instructions for finding the WWN. To find the WWN in a Sun Solaris environment: 1.
Figure 18 Sun Solaris Worldwide Name Finding WWN for AIX, IRIX, or Sequent To find the WWN in an 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, see the manual of the corresponding switch. Creating Host Groups You can connect multiple server hosts of different platforms to one port of your storage system.
The setting is applied to the storage system. Note: After you click the Option button, the dialog box expands to display the list of host mode options. The No. column indicates option numbers. Select a check box of an option you want to specify.
If the host mode of a host group is 0C Windows and an LU path is defined between the host group and a logical volume, you cannot combine the logical volume with other logical volumes to form a LUSE volume (that is, an expanded LU). For detailed information about LUSE, see the HP StorageWorks XP24000 LUN Expansion User’s Guide. • If you register VMware server hosts in a host group, you need to ensure that the host mode of the host group is 01 VMware or 21 VMware Extension.
Notes: • 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 (Figure 4 on page 21). 2.
Figure 20 The Add New WWN Dialog Box (When Registering a Host that Has Previously been Connected to the Storage System) Figure 21 The 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.
2. In the tree, select a host group. 3. From the CU drop-down list above the LDEV list, select a CU number. The LDEV list displays LDEVs in the specified CU image. 4. Select a logical volume from the LDEV list. Next, from the LU Path list, select LUNs indicated by the icon (this icon indicates a LUN to which no LU path is defined). Next, click the Add LU Path button. A message appears displaying information about LU paths to be defined (Figure 22 on page 42).

• 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.
Figure 23 Flow of Authentication of Hosts (In a Fibre Channel environment) Each case in the flow is explained as follows. Case A to Case D in Figure 23 on page 45 corresponds that below. • When performing authentication of host groups • 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.
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.
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.
Figure 25 Flow of Authentication of Fibre Channel Switch Each case in the flow is explained as follows. Case A to Case D in Figure 25 on page 48 corresponds that below. • When performing authentication of Fibre Channel switches by ports: • If the user information for the Fibre Channel switch is registered on the port, and authentication of the Fibre Channel switch is enabled (Case A): Each port authenticates the Fibre Channel switch.
Regardless of the setting on the Fibre Channel switch, the port performs authentication of the Fibre Channel switch, but results in failure. The Fibre Channel switch cannot connect to the storage system. • When not performing authentication of Fibre Channel switches by ports (Case D): The Fibre Channel switch will connect to the storage system without authentication of the host, regardless of whether or not the Fibre Channel switch is configured for authentication with CHAP.
3. In the Port tree, double-click the Subsystem folder. If the storage system contains any Fibre Channel adapters, the Fibre folder appears below the Subsystem folder. 4. Double-click the Fibre folder and Fibre Channel port icon under the Fibre folder. When you double-click the Fibre folder, the Fibre Channel ports contained in the storage system appear as icons. If you double-click the Fibre Channel ports, host groups appear as icons. On the right of each icon is the host group name.
The specified user information for the host is added in blue in the Authentication Information (Host) list of the Authentication window. 7. Click the Apply button in the Authentication window. A message appears and asks if you want to apply the setting to the storage system. 8. Click the OK button to close the message. The setting is applied to the storage system.

Figure 38 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.
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. 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.

Figure 39 The Concatenation List Dialog Box Deleting LU Paths Caution: Do not remove LU paths when host I/O is in progress. To delete LU paths: 1. Start LUN Manager and display the LUN Manager window (Figure 4 on page 21). 2. In the tree, double-click a port. The corresponding host groups are displayed. 3. In the tree, select a host group. The LU Path list displays information about LU paths associated with the selected host group. 4.
Figure 40 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.
d. Double-click the copy destination port to display host groups below the port. e. Right-click the host group to which you want to paste paths. Next, select Paste Paths from the pop-up menu. If a message appears and asks if you want to continue the operation, click the OK button. Note: You cannot paste paths to host groups for initiator ports. 4. Click Apply in the LUN Manager window. A message appears and asks if you want to apply the setting to the storage system. 5.
By default, LUN security is disabled on each port. When configuring your system, you must enable LUN security on ports. Note: If a port has the External attribute, you cannot apply LUN security to the port. 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 (Figure 4 on page 21). 2. In the tree, locate the desired port. 3.
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. Notes: 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.
2. In the upper-right LU Path list or in the lower-right LDEV list, select and right-click the desired command device. Notes: in the tree. • If nothing is displayed in the LU Path list, select a host group • The icon indicates a logical volume to which command device security is already applied. • The icon indicates no logical device. 3. Select Cmd. Dev. Security: Disable -> Enable from the pop-up menu. A message appears asking if you want to apply command device security. 4.
Performing LUN Manager Operations
6 Performing LUN Manager Operations Using Configuration File Loader You can use Configuration File Loader to define Channel Adapter (CHA) settings, Port Settings, and so on. Configuration File Loader allows you to save these settings in a file (called a spreadsheet), and to apply them concurrently to multiple logical volumes using the spreadsheet. For details on the LUN Manager functions that can be defined using Configuration File Loader, see “LUN Manager Spreadsheet Settings” on page 90.
Spreadsheet File Requirements You will need to write the spreadsheet according to specific rules and in a specific format. Figure 43 on page 86 shows an example of a spreadsheet. Declaration Changing Function Tag Adding Comment Deleting Current Configuration Definition (including blank columns) New Configuration Definition (user setting) Figure 43 Sample Spreadsheet All of the formatting requirements in Table 9 on page 86 must be satisfied.
Spreadsheet Components The spreadsheet consists of the following components: • • • • Spreadsheet Declaration (see “Spreadsheet Declaration” on page 87) Function tags (see “Function Tags” on page 87) Configuration definitions (see “Configuration Definitions” on page 88) Comments (see “Comments” on page 89) Spreadsheet Declaration The spreadsheet declaration is required, and is written at the beginning of the spreadsheet.
• 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. • 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.
• 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. Figure 44 on page 89 shows an example of index and parameter definitions.
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 “Setting the CHA Mode” on page 91. • 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 “Port Settings” on page 92.
