Part 1: LUN Configuration and Security Manager XP – LUN Manager LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200 15
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.
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. If paths are defined, hosts can send commands and data to logical volumes and receive data from logical volumes.
After classifying server hosts into host groups, you must associate the host groups to logical volumes. In Figure 2, the hg-lnx host group is associated with three logical volumes (00:00, 00:01, and 00:02). LU paths are defined between the two hosts in the hg-lnx host group and the three logical volumes. Figure 2 LU path configuration in Fibre Channel environments Use LUN Manager to define paths between a single server host and multiple LUs.
• ”Defining and viewing alternate paths” on page 93. 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.
After classifying server hosts into iSCSI targets, you must associate the iSCSI targets to logical volumes. In Figure 3, the hg-lnx iSCSI target is associated with three logical volumes (00:00, 00:01, and 00:02). LU paths are defined between the two hosts in the hg-lnx iSCSI target and the three logical volumes. Figure 3 LU path configuration in iSCSI environments Use LUN Manager to define paths between a single server host and multiple LUs.
• ”Defining LU paths” on page 75 • ”Changing or viewing LU path settings” on page 84 • ”Defining and viewing alternate paths” on page 93 For more information about LUN configuration, see ”Overview of Volume Manager and Custom Volume Size” on page 127. 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 cannot define LU path to pool 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.
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. The two hosts in the hp-lnx host group can only access LUs 00:00, 00:01, and 00:02. The two hosts in the hg-hpux host group can only access LUs 02:01 and 02:02. The two hosts in the hg-solar host group can only access LUs 01:05 and 01:06.
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. To allow administrators to use RAID Manager XP commands, you must ensure that at least one logical device is used as a command device.
• Point-to-point: The simplest fibre topology directly connects two devices together. 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.

default. If a port satisfies certain conditions, you can apply High Speed mode to improve port performance. If a port satisfies certain conditions, you can apply Initiator/External MIX mode so that one part can be used both as an initiator port for Continuous Access XP or Continuous Access XP Journal and as an external port applied to a remote command device. For instructions on defining a remote command device, see the HP StorageWorks External Storage XP user guide.
can apply High Speed or Initiator/External MIX mode in the same way, even though there are four port blocks. 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.
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.

• Port number: You must assign part numbers to iSCSI ports when configuring iSCSI environments. Use LUN Manager to specify a decimal port number within the range of 1 to 65535. A port number’s initial value is 3260. • Keep-alive timer: You must specify the Keep-alive timer when configuring iSCSI environments. The Keep-alive timer is used when there is a connection between an iSCSI port and another iSCSI node.
The array performs user authentication by host groups. Therefore, host groups and hosts must have their own user information for performing user authentication. When a host attempts to connect to the array, 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, the host connects to the array without authentication.
Authentication of hosts (Fibre Channel environments) When a host attempts to connect to the array, the connection results of the authentication of the host differs depending on the host group settings. Figure 9 illustrates the relationship between host group settings and the connection results.
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 D is attached to host group 2, which does not perform authentication of hosts. Therefore, Host D can connect to the array without authentication. Authentication of Fibre Channel switches When a host attempts to connect to the array, the connection results of the authentication of the Fibre Channel switch differs depending on the Fibre Channel switch setting related to each port. Figure 11 illustrates the relationship between Fibre Channel switch settings and the connection results.
Each port does not perform authentication of the Fibre Channel switch. The Fibre Channel switch connects to the array without authentication regardless of whether or not the Fibre Channel switch is configured for authentication with CHAP. • Case C: If the Fibre Channel switch’s user information is not registered on the port Regardless of the Fibre Channel switch’s setting, the port performs authentication of the Fibre Channel switch, but results in failure.
Configure the operating system and iSCSI driver for authentication by iSCSI targets with CHAP. You must specify the host’s user name and secret used for CHAP. For more information, see the documentation for the operating system and iSCSI driver in your environment. • Settings for authentication of ports (required if performing mutual authentication) • On the array: Use LUN Manager to specify each iSCSI target’s user information (user name and secret).
• When the host is not configured for mutual authentication, the host connects to the array. If the host is not configured for authentication by iSCSI targets with CHAP, the authentication fails and the host cannot connect to the array. • Case B: If the host’s user information is registered on the iSCSI target, but authentication of the host is disabled The iSCSI target does not perform authentication of the host.
Figure 13 shows an example of authentication of hosts. In this figure, iSCSI names of host bus adapters (HBAs) are abbreviated as a, b, and so on. 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.
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).
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. Use the LUN Manager pane to define LU paths and apply LUN security to logical volumes.

Part 2: LUN Configuration and Security Manager XP – Volume Manager LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200 125
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).
Before the host can access each LDEV composing an expanded LU (LUSE volume), you must release the expanded LU. Figure 78 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: 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]. • The I/O suppression mode and cache mode settings of LDEVs combined into a LUSE volume must be the same.
host’s host mode is 2C (Windows Extension). If the host mode is not 2C, change the host mode to 2C before performing the Volume Manager operation. Overview of Custom Volume Size This section describes the Custom Volume Size (CVS) function, configuring CVS, and requirements of the storage subsystem ID (SSID).
Figure 80 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. Each VDEV in a parity group has the same configuration, and is assigned the same FVs of the same size and RAID level.
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 82). Figure 82 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.
For OPEN-V volumes, there are four ways to create CVS volumes (Table 22). You can specify from 46 MB (50 cylinders) up to the VDEV’s maximum capacity for a CVS volume’s capacity. Table 22 Creating CVS volumes using Install CV (for OPEN-V) Install CV method Description Specify size and number Used to specify the capacity and number of CVs in the CVS volume you want to create. Divide free space by number Used to create CVS volumes by specifying the number of CVs in the CVS volume to be created.

The boundary value depends on volume emulation types and RAID levels (see Table 28 on page 138). If the emulation type is other than OPEN-V • If the CV capacity unit is MB (megabytes): To calculate the CV’s user area capacity, use the following formula. The resulting user area capacity is expressed in kilobytes.
• The boundary value is expressed in kilobytes. The boundary value depends on volume emulation types and RAID levels (see Table 28 on page 138).
• Boundary values of external LUs are always one kilobyte, regardless of RAID levels. Table 29 Slot capacities Emulation type Slot capacity 3380-xx, NF80-xx 48 3390-xx 58 OPEN-xx (except for OPEN-V) 48 OPEN-V 256 NOTE: • The xx is a variable indicating one or more numbers or letters. • Slot capacity is expressed in kilobytes. Volume Initialize and Make Volume functions You can initialize a CVS volume using one of the following functions: Volume Initialize or Make Volume.
• The CV must not be path-defined (including TrueCopy for z/OS, Continuous Access XP, ShadowImage for z/OS, Business Copy XP, and Continuous Access XP Journal pair volumes). • The CV must not be reserved for Auto LUN XP. • LUSE volumes concatenated with one or more LDEVs belonging to a different VDEV must not exist. • The CV must be read/write-enabled. • The CV must not be a pool volume (pool-VOL) • The CV must not be a journal volume. • The CV must not be a remote command device.
