1 Overview of LUN Manager Operations This chapter provides a very brief overview of the LUN Manager functions. • “Overview of LUN Manager” (page 6) • “Overview of LUN Security” (page 6) Unless otherwise specified, the term storage system in this guide refers to the following disk arrays: • HP StorageWorks XP24000 Disk Array • HP StorageWorks XP20000 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser.
2 About LUN Manager Operations This chapter provides an introduction to Fibre Channel operations, LUN Security, and HP StorageWorks RAID Manager.
A 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 port 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.
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 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, or delete LU paths with LUN Manager.
Figure 2 Enabling LUN Security 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.
entered from open-system hosts. When the administrator enters an RAID Manager command from an open-system host, the RAID Manager command is transferred via the command device to the target logical device. To protect a logical device from RAID Manager commands, you must apply command device security to the logical device. If command device security is applied to a logical device, the device will not be affected by RAID Manager commands even when commands are transferred via a command device to that device.
3 Preparing for LUN Manager Operations This chapter describes the system requirements, instructions for configuring Remote Web Console, enabling the required software, and notes on using LUN Manager.
4 Using the LUN Manager GUI This chapter describes the windows in the LUN Manager GUI. • “LUN Manager Window” (page 13) • “Port Window” (page 19) • “Authentication Window, Fibre Folder Selected” (page 23) • “Authentication Window, Fibre Port Selected” (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.
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 “The WWN List” (page 16). LDEV list This table provides information about the logical volumes in the storage system. For details, see “LDEV List” (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.
3. 4. Group open-system hosts by host group (see “Registering Hosts in Host Groups” (page 37)). Associate host groups with LUs (see “Defining LU Paths by Associating Host Groups to Logical Volumes” (page 39)). 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.
Figure 21 LightPulse Utility/NT Window Finding WWN for HP-UX To find the WWN in an HP-UX environment (see “HP-UX Worldwide Name” (page 32)): 1. 2. 3. Verify that the fibre adapters and the Fibre Channel device drivers are installed. Log in to the HP-UX host with root access. 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. 2. 3. 4.
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 “Host Modes for Host Groups” (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.

will be more helpful because you can name host bus adapters after the host installation site or the host owners. 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.
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.
• Windows Server 2003 SP1 or later • Red Hat Enterprise Linux AS 4 Update 1 or later If you use other operating system than these, make sure that a logical volume is not larger than 2 TB. For information about the maximum value of a logical volume capacity supported by your operating system, contact the vendor of your operating system. To define LU paths: 1. 2. 3. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When Selecting Icon under Fibre Folder)” (page 13)).
This section describes the following operations on host groups, Fibre Channel ports, and Fibre Channel switches for user authentication: • Settings and the connection results in authentication of hosts (see “Host and Host Group Authentication” (page 43)) • Settings and the connection results in authentication of Fibre Channel switches (see “Switch Authentication” (page 46)) • Specifying whether to enable or disable the authentication of hosts in a host group (see “Enabling or Disabling Host Authenticat
1. 2. A host group of the storage system authenticates a host that attempts to connect (authentication of hosts). 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.
(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. “Flow of Authentication of Hosts (In a Fibre Channel environment)” (page 43) illustrates the relationship between host group settings and the connection results in a flow.
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 “Example of Authentication of Hosts” (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).
“Combinations of port settings and connection results” (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 “Flow of Authentication of Fibre Channel Switch” (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.
and secret) specified on the port side matches that stored on the host, the host allows the host group to connect. Configuring Fibre Channel Authentication Enabling or Disabling Host Authentication You can specify whether or not to perform authentication of hosts on each host group. Change the user authentication settings of the host groups to enable or disable authentication of hosts. By default, user authentication is disabled. To enable authentication for hosts in a host group: 1. 2. 3.
3. In the Port tree, select a port or host group on which you want to register user information for a host. The user information for hosts currently registered on the selected port or host group appears in the Authentication Information (Host) list. You can register user information for a host even if the port status is disable however, the registered user information is ignored. 4. 5. . In this case, Right-click any point in the Authentication Information (Host) list.
You should register user information for all the hosts to be connected with 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: It does not matter if you configure the host for authentication by ports with CHAP.

1. 2. 3. Start LUN Manager and display the Port window (“Port Window (When Selecting Icon under Fibre Folder)” (page 19)). In the Package tree, select the Fibre folder or a channel adapter of a Fibre Channel (“Port Window (When Selecting Icon under Fibre Folder)” (page 19)). • If you select the Fibre folder, the Port list displays a list of Fibre Channel ports in the storage system. • If you select a channel adapter, the Port list displays a list of Fibre Channel ports on the channel adapter.
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. 2. 3.
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).
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.
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.

To view a list of concatenated parity groups: 1. 2. 3. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When Selecting Icon under Fibre Folder)” (page 13)). In the LDEV list, select a logical volume (that is, an LDEV) and then right-click the selected volume. Check to see if the Concatenation List command appears in the pop-up menu. • If the Concatenation List command appears, the logical volume is dispersed across parity groups.
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.
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. b. c. Select the host group from the tree. From the LU Path list on the right, select one or more LUNs to which volumes are assigned. If a volume is assigned to a LUN, the columns on the right of the LUN column are not empty. Right-click the selection and then select Copy Paths from the pop-up menu. The selected LUNs turn green. d. e.
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. 2. 3. 4. 5.

(page 88)), 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 “Set UUID Window (When a OpenVMS Server Host is Used)” (page 87)).
Figure 48 Set UUID Window (When a Server Host Other Than OpenVMS is Used) 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.
6 Performing LUN Manager Operations Using Configuration File Loader This chapter provides instructions for performing LUN Manager operations using Configuration File Loader.
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 StorageWorks 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. “Sample Spreadsheet” (page 91) shows an example of a spreadsheet.
Figure 50 Sample Spreadsheet All of the formatting requirements in “Spreadsheet File Formatting Requirements” (page 91) 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.
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. 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.
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.

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. “Second Error Check Flow Chart” (page 105) shows the flow of the second check. The second error check consists of two different types of the checks. These checks are shown in “Second Error Check Flow Chart” (page 105) as the Level 1 and Level 2.
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).
