1 LUN Manager for the XP10000/XP12000 You can connect XP arrays to open system and mainframe hosts using Fibre Channel. Use LUN Manager to configure host groups, logical units (LUs), and Fibre Channel ports. LU configuration overview One of the important tasks in logical unit (LU) configuration is to define I/O paths from hosts to LUs. After the paths are defined, the hosts can send commands and data to the LUs and can receive data from them.
00:01, and 00:02. LU paths are defined between the two hosts in the hg-lnx group and the three logical volumes. Port Host Storage Domain Host Groups Figure 1 LU paths configuration in a Fibre Channel environment LUN Manager lets you define paths between a single server host and multiple LUs. In Figure 1, both hosts in the hg-lnx host storage domain can access the three available LUs. LUN Manager lets you define paths between multiple server hosts and a single LU.
• Up to 255 host groups can be created for one Fibre Channel port. • You cannot define any LU path to journal volumes. • You cannot define any LU path to pool volumes. 16-Port FC/CA CHIP product Although there is not a significant performance gain compared to the 8-port FC/CA CHIP product, the primary advantage of the 16-port FC/CA CHIP product is its increased FC connectivity (or port count). High-speed mode is currently unavailable on the 16-port FC/CA CHIP product.
In Figure 3, the host group hpux01 is associated with six LUs. LU paths are defined between the three hosts in the hpux01 group (WWN_1, WWN_2, WWN_3) and the six logical units LUN00-LUN05. Figure 3 Host group example 1 Figure 4 Host group example 2 LUN Manager can define paths between a single host and multiple LUs. In Figure 4, each of the three hosts in the host group hpux01 can access the six LUs. LUN Manager can also define paths between multiple hosts and a single LU.

For Windows with any FC HBAs when MSCS is not needed. For Windows with D8602 FC HBAs with or without MSCS.
In Figure 5, the hosts in the hpux-G01 group can access LUN0 and LUN1 associated with the same host group, but cannot access LUN0 and LUN1 in the winG02 host group. The hosts in hpuxG01 can only access the two LUs, identified by 01:05 and 02:01; the hosts cannot access the LUs 02:00 and 02:02. Figure 5 Host group example 3 (LUN security) If LUN security is disabled, the hosts will not be able to access most of the LUs. Hosts will have access to only those LUs defined in host group 0.
If you want to use a LUSE volume as a command device, you must specify only the first LU as the command device. Fibre Channel port attributes In Fibre Channel environments, you must configure and set addresses for the Fibre Channel ports. You can enhance system performance by adjusting the data transfer speed at the Fibre Channel ports and changing the channel adapter mode.

Figure 6 shows an example of High Speed mode applied for one or two port clocks when the channel adapter board has 8 ports. In case that the channel adapter board has 16 ports, you can also apply High Speed mode in the same way though there are four port blocks. Figure 6 Differences between high-speed and high-speed (2 port) modes 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.
NOTE: Storage partition administrators can display information or operate only within the allocated SLPR. For more information about SLPRs, see the HP StorageWorks XP Disk/Cache Partition User Guide. Figure 7 LUN Manager pane LUN Manager pane The LUN Manager pane contains the tabs listed in Table 5. Table 5 LUN Manager tabs Tab Use this tab to... LUN Manager Define LU paths and apply LUN security for logical volumes.
Table 6 Icon Fibre Channel port icons for LUN Manager operations (continued) Status A short-wave port in high-speed mode with LUN security A long-wave port in high-speed mode without LUN security A long-wave port in high-speed mode with LUN security LU Path table On the right side of the LU Path tree is a table that displays LU Path information about the hosts in the tree.
When you select a Fibre Channel port in the LU Path tree, the WWN table appears in the lower-left corner of the LUN Manager pane. The WWN table lists host bus adapters that are connected to Fibre Channel ports on the disk array. The table contains the following information: • A list of ports • Host Group: Host groups are used to classify servers (hosts) connected to the disk array. You can create host groups in the LUN Manager pane. • Name: Indicates nicknames for hosts.
Defining LU paths To configure a Fibre Channel environment, complete the following major steps: 1. Find the WWNs of the host bus adapters connected to the Fibre Channel ports. 2. Create host groups (”Creating host groups” on page 23). 3. Register hosts in host groups (”Registering hosts in host groups” on page 24). 4. Associate host groups to logical volumes (”Associating host groups to logical volumes” on page 26).
9. Click OK. The settings are applied to the disk array. The next step is to register hosts to the appropriate host group. Table 9 Host mode options No. Host Mode option When to select option 2 VERITAS Database Edition/Advanced Cluster When VERITAS Database Edition/Advanced Cluster for Real Application Clusters or VERITAS Cluster Server 4.
2. In the LU Path tree, locate the port the host group belongs to and verify that LUN security is enabled. NOTE: If the port icon has a key ( ), LUN security is enabled. If LUN security is not enabled, right-click the port and select Disable->Enable in the shortcut menu. 3. If the desired host has never been connected via a cable to another port in the disk array, skip to step 9. 4.
11.If necessary, enter a nickname for the host bus adapter. 12.Click OK. The new WWN and nickname appear below the selected host group in the LU Path tree. 13.Click Apply in the LUN Manager main pane. A confirmation message appears. 14.Click OK. The settings are applied to the disk array.

To accept the changes to the other ports, click OK. Figure 14 Check WWNs dialog box 8. Click Apply in the LUN Manager main pane. A confirmation message appears. 9. Click OK. The settings are applied to the disk array. Deleting HBAs from host groups 1. Start LUN Manager, and display the LUN Manager pane (Figure 7). 2.
Defining alternate paths LUN Manager can define alternate paths. If an LU path fails, you can switch to its alternate path. To create an alternate path, copy the original path from one port to another. For example, to define an alternate for the LU path between the CL1-A port and logical volume 00:01, copy the LU path from the CL1-A port to another port. If you want to define alternate paths when LUN security is removed, you must redefine the LU path.
4. Click OK. The settings are applied to the disk array. Applying and removing LUN security By default, LUN security is not applied to any ports. When configuring your system, you must apply LUN security to the ports. If a port has the External attribute, you cannot apply LUN security to the port. The icon indicates a port without LUN security and changes to the icon when LUN security is applied. 1. Start LUN Manager, and display the LUN Manager pane (Figure 7). 2. Right-click a port in the LU Path tree.
2. Click the Port tab. The Port pane appears. Figure 15 Port pane NOTE: The storage partition administrators can display ports and operate within only the allocated SLPR. For more information about SLPRs, see the HP StorageWorks XP Disk/Cache Partition User Guide. Port pane The Port pane includes the package tree, port table, and change port mode box. Package tree Use this tree to select the port. The Fibre folder appears under the Subsystem folder at the top of the tree.
Port table This table appears when you select an icon under the Fibre folder in the Package tree. If you select a channel adapter in the tree, this table displays all ports on the channel adapter. If you select a port block, this table displays all ports in the port block. The table lists the following for Fibre Channel CHA packages: • Port Name: Displays port names • Type: Fibre indicates a Fibre Channel port, used for connecting open system hosts.
6. Click Apply. A confirmation message appears. 7. Click OK. The settings are applied to the disk array. Switching to standard or high-speed mode Channel adapter boards can be set for standard or high-speed mode. If possible, apply high-speed mode to channel adapters to improve the system performance. Be aware that you can only apply high-speed or high-speed (2 port) mode to channel adapters that satisfy certain requirements. 1. Start LUN Manager, and display the LUN Manager pane (Figure 7). 2.

2 Volume Management for the XP10000/XP12000 Use Volume Management to perform the following tasks: • ”Volume Management (LU Size Expansion)” on page 37) • ”Volume Size Configuration (VSC)” on page 38) Volume Management (LU Size Expansion) Volume Management (LU Size Expansion or LUSE) combines two or more LDEVs to function as a larger LDEV. As a result, a host can access a greater amount of storage with a smaller number of LDEVs. Figure 16 shows the effect of a LUSE configuration.
• When you combine a LUSE volume with another LUSE volume, the range of LDEVs should not be overlapped. For example, if you combine LDEV00, LDEV03 and LDEV05 into LUSE 1, LDEV02 and LDEV04 into LUSE 2, and LDEV06 and LDEV07 into LUSE 3, you can also combine LUSE 1 and LUSE 3. However, you cannot combine LUSE 1 and LUSE 2, because the LDEV range in LUSE 1 and LUSE 2 is overlapped. • A maximum of 256 expanded logical units (LUs) can be configured on the same port.
A small custom volume can be used as a command device. This leaves the rest of the LDEV free for other uses. VSC operations VSC operations include the following: • Volume to Space: Formats one or more LDEVs on a selected VDEV into free space, which can be used to install one or more custom volumes using the Install CV function, or left as free space for future use. • Install CV: Creates custom volumes from free space.
Parity group configuration This section explains the parity group configuration of emulation types other than OPEN-V. OPEN-V volumes always consist of variable sized volumes instead of fixed-size volumes (FVs). To use OPEN-V, parity groups must be enabled to support the OPEN-V emulation type. To enable OPEN-V, contact your HP account support representative. For emulation types other than OPEN-V, one parity group consists of a maximum of 16 VDEVs.
Before changing ordinary target ports or RCU target ports to initiator ports, make sure that no I/Os (such as Extended Copy commands) are being performed from the host server to the affected ports. You can change the port type of free ports only. Volume to Space operation The Volume to Space function converts one or more LDEVs (fixed or custom volumes) into free space, which deletes the selected LDEVs from that volume.
NOTE: Allocating custom volumes in descending order of capacity optimizes custom volume allocation during the Install CV process. As defined in Table 14, VSC does not work with OPEN-L and OPEN-M emulation types. VSC supports OPEN-3, OPEN-8, OPEN-9, OPEN-E, and OPEN-V emulations.
Table 16 shows specified and actual capacities of various open system custom volume sizes. Table 16 Capacities of open system custom volume sizes Setting size (MB) User size (MB)1 Notes 36 36.15625 Minimum custom volume size (other than OPEN-V) 46 48.875 Minimum custom volume size (OPEN-V) 500 500.625 1000 1000.546875 2000 2000.390625 2347 2347.03125 Maximum OPEN-3 volume size 7007 7007.34375 Maximum OPEN-8 volume size 7042 7042.5 Maximum OPEN-9 volume size 13893 13893.
• The user-specified CV capacity is expressed in megabytes. To calculate the entire capacity of a CV, use the following formula. The resulting entire capacity is expressed in megabytes: ↑ user-area-capacity ÷ boundary-value ↑ × boundary-value ÷ 1024 NOTE: • Round up the value enclosed by two up arrows (↑) to the nearest whole number. • The user area capacity is expressed in kilobytes. • The boundary value is expressed in kilobytes.
Emulation types other than OPEN-V • If the unit for CV capacity is MB (megabytes): To calculate the user area capacity of a CV, use the following formula. The resulting user area capacity is expressed in kilobytes. ↑↑ user-specified-CV-capacity × 1024 ÷ capacity of a slot ↑ ÷ 15 ↑ × capacity of a slot × 15 NOTE: • Round up the value enclosed by two up arrows (↑) to the nearest whole number. • The user-specified CV capacity is expressed in megabytes. • The capacity of a slot is expressed in kilobytes.

LUSE operations Users belonging to the Administrator and StorageAdmin groups can perform Modify VSC and Modify LUSE operations. Starting LUSE operations 1. Click the Volume Management button ( ). The Volume Management pane appears. Figure 21 Volume Management pane Volume Management pane The Volume Management pane includes the following sections. LDEV Information tree The top of the pane shows a tree and list of CU numbers (CUxx) and LDEV numbers (xx:xx).
The table contains the following information: • LDEV: An LDEV status icon (Table 22), a CU number, and an LDEV number. If the selected LDEV is a LUSE volume, the LDEV number of the top LDEV in the LUSE volume is displayed. An LDEV number that ends with a # indicates that the LDEV is an external LU (for example, 00:01#). NOTE: If an LDEV number ends with V (for example, 00:01V), the LDEV is a virtual volume (V-VOL). For more information about V-VOLs, see the HP StorageWorks Snapshot XP User Guide.
Volume Count list Specifies the number of LDEVs that should form a LUSE volume. For example, if you select 3 in the Volume Count list, three LDEVs are expected to form a LUSE volume and then three LDEVs are added to the Expanded LDEVs list. You can select an LDEV only from the Volume Count list. You cannot select a LUSE volume. Free LDEVs table Lists the LDEVs, VSC volumes, and LUSE volumes that can constitute a LUSE volume in combination with the LDEV selected as a top LDEV in the Select an LDEV list.
Viewing LUSE configuration information • The LDEV Information tree displays an outline view of the CU and LDEV numbers installed on the disk array in a hierarchical structure. • The LDEV Information table displays detailed information for all open system LDEVs in the selected CU. If you select a normal LDEV, the information in this section is for the top LDEV. If you select a LUSE volume, the information in this table is for all of the LDEVs in the LUSE volume.

When the CU number of another SLPR is used check box is selected, you can select the number of an LDEV that does not exist in an SLPR to which the parity group does not belong. When the check box is cleared, you can only select the number of an LDEV in an SLPR to which the parity group belongs.
14.Verify that the information is correct and click OK. The Customized Volume pane is displayed. The created custom volumes are shown in blue. NOTE: You cannot manipulate the VDEVs denoted by blue icons until you apply the changes to the disk array or cancel them, but you can initialize additional custom volumes in VDEVs denoted by red icons. 15.Click Apply. A confirmation message appears. 16.Click OK. The Make Volume operation begins.
2. Right-click any part of the Parity Group - LDEV tree and select Volume Initialize. The Volume Initialize pane is displayed. Figure 35 Volume Initialize pane Use this pane to initialize custom volumes other than OPEN-V. The top area is the CV setting information area and shows detailed information about the custom volumes to be initialized. The bottom area is the LDEV number setting area and is used to set the CU and LDEV numbers for the custom volume to be initialized. 3.
NOTE: The CU number of another SLPR is used check box is displayed only when you logged in as a user in the StorageAdmin group with full array access and when there are two or more SLPRs. When the CU number of another SLPR is used check box is selected, you can select the number of an LDEV that does not exist in an SLPR to which the parity group does not belong. When the check box is cleared, you can only select the number of an LDEV in an SLPR to which the parity group belongs.
NOTE: The SSID of another SLPR is used check box is displayed only when you logged in as a user in the StorageAdmin group with full array access and when there are two or more SLPRs. When the SSID of another SLPR is used check box is selected, you can select the number of an SSID that does not exist in an SLPR to which the parity group does not belong. When the check box is cleared, you can only select the number of the SSID in the SLPR to which the parity group belongs.
9. Click the Apply button in the Customized Volume pane. When prompted for confirmation, click OK. The words Format in progress appear next to the Progress Bar. 10.When the percentage shown on the Progress Bar reaches 100%, a message informs you that the format operation is complete. Click OK. 11.Confirm that the status of the volume is Normal. Formatting all blocked volumes Use the Format All pane to format all blocked volumes in parity groups in the local disk array and/or external disk array.
CAUTION: Operations in this pane must be performed only on external volumes with data areas that are zero-formatted. Figure 37 Write to Control Blocks pane • Target ExG: External volume groups containing volumes to be made usable. • ExG: External volume group numbers • External Storage: Information about external disk arrays • Add button: Moves external volume groups selected in the Candidate ExG list to the Target ExG list.
NOTE: The term “zero-formatting” refers to a formatting operation that writes the number 0 (zero) to the entire disk area. For more information about zero-format volumes, see the documentation for the mainframe system or external disk array you are using. 2. Use External Storage XP to map the zero-formatted external volumes and register the volumes in an external volume group. For more information, see the HP StorageWorks External Storage XP Users Guide.
