About this guide
1 Overview of LUN Manager The XP12000/XP10000/SVS200 arrays integrate the following storage environments to provide advanced storage solutions: • Fibre Channel: Fibre Channel is a protocol that enables fast data transfers and can be used for configuring a storage area network (SAN). To use an array as SAN storage, you should attach host servers to the array's Fibre Channel ports.
Figure 1 Array integrating Fibre Channel, iSCSI, and NAS environments You can connect the array to open-system server hosts on different platforms (for example, UNIX and PC servers). To configure a system that includes open-system hosts and an array, 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.
Configuring LU paths in Fibre Channel environments After open-system hosts and the array are physically connected by cables, hubs, and so on, you must use LUN Manager to establish I/O paths between the hosts and logical volumes. This defines which host can access which logical volume. Logical volumes that open-system hosts can access are referred to as logical units (LUs). Paths between open-system hosts and LUs are referred to as LU paths.
Figure 2 LU path configuration in Fibre Channel environments Use LUN Manager to define paths between a single server host and multiple LUs. In Figure 2, both hosts in the hg-lnx host group can access the three LUs. Use LUN Manager to define paths between multiple server hosts and a single LU. In Figure 2, the LU identified by CU-LDEV number 00:00 is accessible from both hosts belonging to the hg-lnx host group. In Figure 2, LUs associated with the hg-lnx host group are addressed by numbers 0000 to 0002.
NOTE: • In Fibre Channel environments, you can define up to 1,024 LU paths for one host group and up to 1,024 LU paths for one port. • You cannot define LU paths to LUN On-Demand volumes. • You cannot define LU paths to volumes reserved by Auto LUN XP. • You can create up to 255 host groups for one Fibre Channel port. • You cannot define LU paths to journal volumes. • You cannot define LU paths to pool volumes.
Figure 3 LU path configuration in iSCSI environments Use LUN Manager to define paths between a single server host and multiple LUs. In Figure 3, both hosts in the hg-lnx iSCSI target can access the three LUs. Use LUN Manager to define paths between multiple server hosts and a single LU. In Figure 3, the LU identified by CU-LDEV number 00:00 is accessible from both hosts belonging to the hg-lnx iSCSI target. In Figure 3, LUs associated with the hg-lnx iSCSI target are addressed by numbers 0 to 2.
• Defining and viewing alternate paths For more information about LUN configuration, see Overview of Volume Manager and Custom Volume Size. NOTE: • In iSCSI environments, you can define up to 1,024 LU paths for one iSCSI target and up to 1,024 LU paths for one port. • You cannot define LU paths to LUN On-Demand volumes. • You cannot define LU paths to volumes reserved by Auto LUN XP. • You can create up to 64 iSCSI targets for one Fibre Channel port. • You cannot define LU paths to journal volumes.
Figure 4 LU path configuration in NAS environments Configuring LUN security To protect mission-critical data in the array 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. NOTE: • You cannot apply LUN security to NAS ports. • If a port has 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 LUs associated with the host group the hosts belong to. Hosts cannot access LUs associated with 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 5, LUN security is enabled on port CL1-A.
By default, LUN security is disabled on each port. When you configure the system, you must enable LUN security on each port to which hosts are connected. For more information, see Using LUN security. Configuring LUs for use by RAID Manager XP System administrators can enter RAID Manager XP commands from open-system hosts to perform Continuous Access XP and Business Copy XP operations on logical devices. For example, administrators can enter RAID Manager XP commands to create or split pairs.
Figure 7 FC-AL and Point-to-point topologies When configuring the system, use the LUN Manager pane to specify whether the hosts and array are connected by a fabric switch. If you use a fabric switch, you must specify FC-AL or point-to-point in the LUN Manager pane (by default, FC-AL is specified). If you use a fabric switch, see the fabric switch's documentation to learn whether you should use FC-AL or point-to-point. Some fabric switches require that you specify point-to-point to get the system running.

ports where a larger amount of data is transferred, you can optimize system performance. If you set a slower data transfer speed for ports where a smaller amount of data is transferred, you can also optimize performance. For more information, see Specifying a Fibre Channel port's data transfer speed. Standard, High Speed, and Initiator/External MIX modes Channel adapter boards have built-in ports used for connecting hosts and an array.
Figure 8 Ports in High Speed 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. These two ports can exclusively use channel processors and fibre optic processors (FOPs) that would otherwise be reserved for the other two ports. Therefore, system performance improves. By balancing workloads on processors, you can expect a greater improvement in system performance.
NOTE: • Sometimes Standard, High Speed, and Initiator/External MIX modes are collectively referred to as Fibre PCB modes. PCB is an acronym for printed circuit board. The array documentation sometimes uses the term PCB when referring to a channel adapter, which is a printed circuit board used for connecting hosts and an array. • Storage partition administrators cannot apply High Speed or Initiator/External MIX mode.

iSCSI port and iSNS server settings You must make settings on iSCSI ports (and iSNS servers, if necessary) when configuring iSCSI environments. Use LUN Manager to specify the following items when configuring iSCSI environments. For instructions, see Defining LU paths and Making settings on iSCSI ports and iSNS servers. • IP address: You must specify the iSCSI port's IP address when configuring iSCSI environments. In LUN Manager, the initial value of the iSCSI port's IP address is 192.168.0.
• Whether to register iSCSI ports in iSNS servers: The iSNS server is a server computer on which an iSNS service is installed. iSNS is an acronym for Internet Storage Name Service. This server manages IP addresses and iSCSI names of iSCSI ports. Using iSNS servers is optional. If you configure and use iSNS servers, iSCSI ports are easily discovered and managed. NOTE: For more information about configuring iSNS servers, see the iSNS-related documentation.
requires authentication of the host, authentication is performed for the host. When the host is successfully authenticated, processing goes to the next phase. After authentication of the host succeeds, if the host requires user authentication for the host group that is connection target, the authentication of host groups phase starts. In this way, host groups and hosts authenticate with each other, that is, mutual authentication. In the authentication of host groups phase.
Figure 9 Authentication of hosts (Fibre Channel environments) Case A to Case D in Figure 9 is explained as follows: • Case A through Case C: When performing authentication of host groups • Case A: If the host's user information is registered on the host group, and authentication of the host is enabled The host group authenticates the user information sent from the host.
The host connects to the array without authentication of the host regardless of whether or not the host is configured for authentication by host groups with CHAP. In this case, although you do not need to register the host's user information on the host group, you can register the user information. NOTE: You should register the user information for all hosts to be connected to a host group that performs authentication of hosts.
Host B's user information is also registered on host group 1, but the authentication setting is disabled. Therefore, Host B can connect to the array without authentication. Host C's user information is not registered on host group 1. Therefore, when Host C tries to connect to the array, authentication fails and the connection request is denied regardless of Host C's setting. Host D is attached to host group 2, which does not perform authentication of hosts.
• When the Fibre Channel switch is not configured for mutual authentication, the Fibre Channel switch connects to the array. If the port's Fibre Channel switch is not configured for authentication with CHAP, the authentication fails and the Fibre Channel switch cannot connect to the array. • Case B: If the Fibre Channel switch's user information is registered on the port, but authentication of the Fibre Channel switch is disabled Each port does not perform authentication of the Fibre Channel switch.
• Settings for authentication of hosts • On the array: Use LUN Manager to specify whether authentication of hosts is performed on each iSCSI target. On an iSCSI target that performs authentication, register user information (iSCSI name, user name, and secret) of hosts allowed to connect to the iSCSI target. A secret is a password used in CHAP authentication. When registering user information, you can also enable or disable authentication on a host basis.
Figure 12 Authentication of hosts (iSCSI environments) Case A to Case D in Figure 12 are explained as follows: • Case A through Case C: When connecting via an iSCSI target that performs authentication of hosts • Case A: If the host's user information is registered on the iSCSI target, and authentication of the host is enabled The iSCSI target authenticates the user information sent from the host.
Regardless of the setting on the host, the iSCSI target performs authentication of the host, but results in a failure. The host cannot connect to the array. • Case D: When connecting via an iSCSI target that does not perform authentication of hosts The host connects to the array without authentication of the host regardless of whether or not the host is configured for authentication by iSCSI targets with CHAP.
Figure 13 Example of authentication of hosts (iSCSI environments) In Figure 13, iSCSI target 1 performs authentication of hosts, but iSCSI target 2 does not. Host A's user information is registered on iSCSI target 1, and the authentication setting is enabled. Therefore, if authentication of the host succeeds, Host A can connect to the array (or processing goes to the authentication of the iSCSI target).
For more information about configuring hosts, see the documentation for the operating system and iSCSI driver in your environment. Authentication of iSCSI targets (performing mutual authentication) When authentication of a host succeeds, the host performs authentication of the iSCSI target in reverse if the host requires (mutual authentication).
Overview of LUN Manager
2 Preparing to use LUN Manager System requirements To use LUN Manager, you need: • XP12000/XP10000/SVS200 array • LUN Manager optional program • WWW client computer connected to the array via a LAN To use LUN Manager, you must use the WWW client computer to log on to the SVP. When you are logged on, Command View XP or XP Remote Web Console, which is a Java® applet, is downloaded to the WWW client computer. You can perform LUN Manager operations in Command View XP or XP Remote Web Console.
Preparing to use LUN Manager
3 LUN Manager panes When you start LUN Manager, the Command View XP or XP Remote Web Console main pane displays the LUN Manager, Port, and Authentication panes. This chapter describes these panes. LUN Manager pane When you click the icon in the Command View XP or XP Remote Web Console main pane, LUN Manager starts and the LUN Manager pane appears.

6 Finding an open-system host's World Wide Name (WWN) If you are configuring a Fibre Channel environment, you must verify that the fibre adapters and Fibre Channel device drivers are installed on the open-system hosts. Next, you must find the World Wide Name (WWN) of the host bus adapter 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 chapter describes how to find a host's WWN.

Finding WWNs in AIX, SGI Irix, or Sequent environments To find WWNs in AIX, SGI Irix, or Sequent environments, use the fibre switch connected to the host. The method for 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 fibre switch's documentation. Finding WWNs in HP-UX environments 1.
NOTE: When an A5158 Fibre Channel adapter is used, enter the following for the device name at the command line prompt: /usr/sbin/ioscan -fnC fc 6. Record the Fibre Channel device file name (for example, /dev/td0). NOTE: When the A5158 Fibre Channel adapter is used, enter the following to list the WWN for the device with the device file name: /opt/fcms/bin/fcmsutil 7. Record the WWN and repeat the above steps for each Fibre Channel device you want to use.
7 Overview of Volume Manager and Custom Volume Size Volume Manager and Custom Volume Size (CVS) are functions for open systems and mainframe systems. To use these functions, you need the software called HP StorageWorks LUN Configuration and Security Manager XP. This chapter describes Volume Manager and CVS. Overview of Volume Manager This section describes the Volume Manager function and configuration of LUSE volumes (expanded LUs).
Figure 76 LUSE configuration Volume Manager guidelines The following are the specifications and restrictions on LDEVs used to configure a LUSE volume: • Open volumes (OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V) are supported. • The number of LDEVs combined into a LUSE volume must be within the range of 2 to 36. NOTE: The number of expanded LUs (LDEVs) should not exceed 36, even if the LUSE volume contains another LUSE volume.
• The maximum capacity of a LUSE volume is 60 TB. NOTE: When a host accesses a LUSE volume, the host can only access less than 2 TB of the LUSE volume's address area. • • • • • Combining command devices and Just In Time volumes into a LUSE volume is not supported. The access attribute must be set to Read/Write. Combining internal LUs, external LUs, and virtual volumes (V-VOLs) is not supported. During online, the host mode must not be 0x0C [Windows].
CAUTION: Note the following points when you perform a Volume Manager operation using a path-defined LDEV: • If a path is defined from a Windows 2000, Windows Server 2003, or AIX 5.2 host to an LDEV, you can use the LDEV for Volume Manager operations using a path-defined LDEV. However, if a path is defined from a host running another operating system to an LDEV, you cannot use the LDEV for Volume Manager operations using a path-defined LDEV.
Figure 77 Overview of Volume Initialize function Figure 78 Overview of Make Volume function Parity group configuration One parity group consists of a maximum of 16 VDEVs. For RAID-5 (7D + 1P) or RAID-6 (6D + 2P) levels, a maximum of 512 fixed-size volumes (FVs) and a certain amount of free space are available in one VDEV. For other RAID levels, a maximum of 256 FVs and a certain amount of space are available in one VDEV.
Figure 79 Parity group configuration As the result of CVS operations, a VDEV contains FVs, CVs, and free spaces that are delimited in logical cylinders. Sequential free spaces are combined into a single free space (see Figure 80). Figure 80 Virtual CVS volume configuration Volume to Space function This function converts one or more LDEVs (FVs or CVs) into free space, which deletes the selected LDEVs from that VDEV.

• Viewing VDEV and LDEV configuration information You can view configuration information for VDEVs and LDEVs on the Customized Volume pane (Figure 90). This pane shows an outline of group numbers, parity group numbers, RAID levels, and VDEV numbers and a table of CU:LDEV numbers, emulation types, LDEV capacities, and path settings of VDEVs selected in the tree.
NOTE: To select two or more adjacent LDEVs, select the LDEVs while pressing the Shift key. To select two or more discrete LDEVs, select the LDEVs while pressing the Ctrl key. 5. Right-click the selected LDEVs, and select Volume to Space. The Volume to Space Confirmation dialog box appears. 6. If the listed volumes are correct, click OK. The change is not yet implemented in the array, but the following changes appear on the Customized Volume pane: • Selected LDEVs are listed as Free.
• • • • Specify capacity and number Divide free space by number Divide free space by capacity Set remaining space as volume. NOTE: If there are two or more free spaces in the VDEV, Divide free space by number, Divide free space by capacity, and Set remaining space as volume are not available. c. Specify the CVS volume's capacity or the number of CVs according to the selected method.
7. Select one or more CVS volume numbers to assign CU and LDEV numbers. 8. In the Select CU No. list, select a CU number. 9. In the Select LDEV No. table, select an LDEV number from the white LDEV numbers. Gray indicates LDEV numbers that are not selectable, white indicates unused LDEV numbers, and blue indicates available LDEV numbers. The CU and LDEV numbers appear in the CU:LDEV field of the CVS volume-setting information table.
Deleting CVS volumes To delete an individual CVS volume within a VDEV, use the Volume to Space operation (see Converting logical volumes to space ). Converting CVs back to FVs (Volume Initialize operation) CAUTION: The Volume Initialize function is a destructive operation. Data on the CVS volume being converted is lost when the operation is complete. You are responsible for backing up data as needed before performing this operation.
If the selected LDEV number's boundary area does not have an SSID, the SSID setting pane appears. Go to step 8. If the selected LDEV number's boundary area has an SSID, go to step 10. 6. On the SSID setting pane, select the CU number. 7. In the Input SSID list, select a new SSID. NOTE: When you log in as a storage administrator and the SSID number of another SLPR is used check box is selected, you can also enter an SSID in the Input SSID list. 8. Click Set.
1. On the upper right of the XP Remote Web Console main pane, select a CU group from the drop-down list. 2. From the Customized Volume pane, select the LDEV folder in the Parity Group - LDEV tree to display a list of VDEVs, and select a VDEV for OPEN-V. The LDEV Information table displays detailed information about the LDEVs.
c. Click Set to display the setting in the LDEV information table. To remove CVS volume settings displayed in the LDEV information table, do the following: • To remove a setting, select the CVS volume, and click Delete. When a confirmation message appears, select OK. • To remove all settings, click Clear. When a confirmation message displays, click OK. d. To create other CVS volumes, repeat step 5a through step 5c. After setting all CVS volumes, go to step 6. 6. Click Next.
NOTE: Setting changes are not yet implemented in the array. You cannot manipulate VDEVs denoted by blue icons until you click Apply to apply the changes to the array or Cancel to cancel them, but you can initialize additional CVS volumes in VDEVs denoted by red icons. 18. To apply changes to the array, click Apply (or Cancel to cancel them). NOTE: If desired, you can make settings on the Volume Initialize function (see Converting CVs back to FVs (Volume Initialize operation)) before clicking Apply.
• To format all blocked internal LUs, right-click LDEV at the top of the tree, and select Format All. In the Format All pane, select Internal PG from the Parity Group Type list. Confirm that the list displays internal LUs to be formatted, and click OK. • To format all blocked external LUs, right-click LDEV at the top of the tree, and select Format All. In the Format All pane, select External PG from the Parity Group Type list. Confirm that the list displays external LUs to be formatted, and click OK. 9.
To overwrite control blocks in volumes in an external LU group: 1. On the upper right of the XP Remote Web Console main pane, select a CU group from the drop-down list. 2. From the Customized Volume pane, right-click the LDEV folder at the top of the tree, and select Write to Control Blocks. 3. In the Write to Control Blocks pane, select the desired external LU group from the Candidate ExG list, and click Add. The selected external LU group moves to the Target ExG list.
