1 Overview of LUN Manager Operations This chapter provides a very brief overview of the LUN Manager functions. • Page 6 • Page 6 Unless otherwise specified, the term storage system in this guide refers to the following disk arrays: • HP XP24000 Disk Array • HP XP20000 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser. Actual windows may differ depending on the operating system and browser used.
2 About LUN Manager Operations This chapter provides an introduction to Fibre Channel operations, LUN Security, and HP RAID Manager. • Page 7 • Page 7 • Page 9 • Page 10 Overview of 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.
1A and three Windows hosts are connected to port 1B, you cannot register all 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 with logical volumes. In (page 8), the host group hg-lnx is associated with three logical volumes (00:00:00, 00:00:01, and 00:00:02).
the host. You do not need to restart the system when you add, change, or delete LU paths with LUN Manager. 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 (page 29).
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 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.

4 Using the LUN Manager GUI This chapter describes the windows in the LUN Manager GUI. • Page 13 • Page 18 • Page 23 • Page 25 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. The storage partition administrators can display information or perform the operation within only the allocated SLPR (storage management logical partition).
Item Description WWN list The WWN list is available when you select an item related to a Fibre Channel port from the tree. For details, see (page 16). LDEV list This table provides information about the logical volumes in the storage system. For details, see (page 17). Other components in this window are explained in later sections. LU Path Tree Use this tree to find information about LU paths.
When you double-click a port for which LUN security is disabled, the host groups, except for the first host group (host group 0), are unavailable. LU Path List On the right side, a table displays LU path information about the host group specified in the tree. Figure 6 LU Path List Item Description LUN LUNs assigned to logical volumes. LUNs are address numbers assigned to LUs, which are logical volumes that can be accessed by open-system hosts.
Item Description Capacity Size of each logical volume. RAID RAID level for each logical volume. If the logical volume is an external volume or a virtual volume, the RAID column does not show the RAID level, but shows a hyphen (-) instead. When the parity groups are combined, an asterisk (*) and a number appear on the right of the RAID level. For example, 5(7D+1P)*2 indicates that two parity groups are combined. Paths Number of alternate paths, if any.

5 Performing LUN Manager Operations This chapter provides instructions for performing LUN Manager operations. • Page 29 • Page 29 • Page 40 • Page 58 • Page 63 • Page 78 • Page 78 • Page 79 • Page 81 • Page 82 Launching LUN Manager for Fibre Channel Operations To start LUN Manager, take the following steps: 1. Start the Web browser. 2. Enter the following URL in the Web browser and then press the key. The Remote Web Console login dialog box appears.
Finding WWNs If you are configuring a Fibre Channel environment, you must verify that Fibre Channel adapters and Fibre Channel device drivers are installed on the open-system hosts. Next, you must find the 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 a open-system host, consisting of 16 hexadecimal digits. This section describes how to find the WWN of a host.
Figure 21 LightPulse Utility/NT Window Finding WWN for HP-UX To find the WWN in an HP-UX environment (see (page 32)): 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. 5. This will list the attached Fibre Channel devices and their device file names. Record the Fibre Channel device file name (for example, /dev/fcms0).
Figure 22 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 23 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.
4. Select a host mode from the Host Mode list. When selecting a host mode, you must consider the platform and some other factors (see (page 34) for details). CAUTION: 5. 6. • Do not select Reserve from the list. Reserve indicates that the host mode is not currently supported. • If the microcode version is updated to 60-08-0X-XX/XX or later, Reserve is not displayed in the drop-down list. If you set the system option mode 847 to ON, Reserve can be displayed in the drop-down list.

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 ◦ 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.
Figure 28 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 (page 43) 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.
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. ◦ 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.
Figure 29 Example of Authentication of Hosts In (page 45), 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).
(page 46) shows the relationship between the combinations of host group settings and the connection results in authentication of hosts. Regardless of whether or not the host is configured for authentication by ports with CHAP, the connection results are as follows, unless otherwise noted.
Figure 30 Flow of Authentication of Fibre Channel Switch Each case in the flow is explained as follows. Case A to Case D in (page 47) 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.
If the Fibre Channel switch of the port is not configured for authentication with CHAP, the authentication fails and the Fibre Channel switch cannot connect to the storage system. ◦ If the user information for the Fibre Channel switch is registered on the port, but authentication of the Fibre Channel switch is disabled (Case B): The ports do not perform authentication of the Fibre Channel switch.

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 ((page 19)). 2. In the Package tree, select the Fibre folder or a channel adapter of Fibre Channel ((page 19)). 3. • If you select the Fibre folder, the Port list displays a list of Fibre Channel ports in the storage system.
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).
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.

Viewing a List of Concatenated Parity Groups The storage system supports concatenation of parity groups. If parity groups are concatenated, a logical volume can be dispersed across the concatenated parity groups. Dispersal of logical volumes can provide faster access to data (particularly, faster sequential access to data). NOTE: Only an HP service representative can concatenate parity groups. If you have any questions about concatenation of parity groups, ask your HP service representative.
6. 7. 8. Click OK to close the message. The selected LU path is removed from the table. Click Apply in the LUN Manager window. A message appears asking whether to apply the setting to the storage system. Click OK to close the message. The settings are applied to the storage system and the specified LU paths are deleted. 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.
c. d. Right-click the copy destination port. Select Paste from the pop-up menu. If a message appears and asks if you want to continue the operation, click OK. NOTE: You cannot paste paths to initiator ports. To copy one or more (but not all) LU paths defied to a host group, take the following steps: a. Select the host group from the tree. b. From the LU Path list on the right, select one or more LUNs to which volumes are assigned.
Figure 46 Alternate Paths Dialog Box 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.
7. Click the Apply button in the LUN Manager 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 change in the security settings is applied to that storage system. Disabling LUN Security CAUTION: Do not disable LUN security on ports when host I/O is in progress. To disable LUN security on a port: 1. Start LUN Manager and display the LUN Manager window ((page 13)). 2. In the tree, locate the desired port. 3.
1. 2. 3. Start LUN Manager and display the LUN Manager window ((page 13)). In the upper-right LU Path list or the lower-right LDEV list, select and right-click the desired logical device. • If nothing is displayed in the LU Path list, select a host group • The icons • The icon and in the tree. indicate command devices. indicates no logical device. From the pop-up menu, select Command Device: Disable -> Enable. A message appears, asking if you want to use the logical device as a command device.
5. Click the Apply button in the LUN Manager window. A message appears and asks if you want to apply the setting to the storage system. 6. Click the OK button to close the message. The settings are applied to the storage system. Related topic To remove command device security from a logical device, you must select and right-click the logical device ( ) in the upper-right LU Path list or the lower-right LDEV list and then select Cmd. Dev. Security: Enable -> Disable from the pop-up menu.
6. In the Set UUID window (see (page 85) and (page 85)), enter a UUID in the UUID box. If a UUID is already specified in the UUID box, you can change it. However, if multiple LUNs, or N/As are selected, the UUID box is blank. • For an OpenVMS server host, use a numerical value from 1 to 32,767 (see (page 85)). • For a server host other than OpenVMS, use up to 64 ASCII characters (letters, numerals, and symbols) for a UUID (see (page 85)).
NOTE: When the host mode 05 OpenVMS is used, the disk storage system version cannot be downgraded if a host mode option 33 is set to ON, or a UUID is set. If you want to downgrade the version, make sure the host mode option 33 is set to OFF, clear the setting of UUID, and then perform the downgrade. Though a host mode option 33 is set to OFF and the setting of UUID is cleared, an alarm message may be displayed. In this case, retry the downgrade.
6 Performing LUN Manager Operations Using Configuration File Loader This chapter provides instructions for performing LUN Manager operations using Configuration File Loader. • Page 87 • Page 88 • Page 89 • Page 93 • Page 100 Using Configuration File Loader Use Configuration File Loader to define channel adapter (CHA) settings, port settings, and so on.
Figure 49 Configuration File Loader Operation Flow Chart This chapter provides an overview of LUN Manager spreadsheets that are required for settings using Configuration File Loader. For details on how to import spreadsheets, see the HP XP24000/XP20000 Remote Web Console User Guide. Spreadsheet File Requirements You will need to write the spreadsheet according to specific rules and in a specific format. (page 89) shows an example of a spreadsheet.
Figure 50 Sample Spreadsheet All of the formatting requirements in (page 89) must be satisfied. Table 10 Spreadsheet File Formatting Requirements Item Requirements File type Text file File name Extension must be .spd. Maximum number of letters for the file name is 32 including the extension. The following symbols cannot be used for the file name: \ / : , ; * ? “ < > | and space. File path must be under 255 letters.
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.
• 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.
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.
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.
