1 LUN Manager for the XP128/XP1024 You can connect XP arrays to open system and mainframe hosts using iSCSI (Internet Small Computer System Interface), Fibre Channel, and Network Attached Storage (NAS). Use LUN Manager to configure host groups, logical units (LUs), and Fibre Channel and NAS ports. You can also configure NAS cache settings. LU configuration overview One of the important tasks in logical unit (LU) configuration is to define I/O paths from hosts to LUs.
• Up to 255 hosts can be included in all the host groups for one Fibre Channel port • Up to 16 hosts can be included in all the host groups for one iSCSI port Configuring LU paths in a Fibre Channel environment Before defining LU paths, you must classify server hosts by host storage domains. For example, if Linux and Windows® hosts are connected to the disk array, you must create a separate host storage domain for each host type.
In Figure 1, the LUs associated with the hg-lnx domain are addressed by numbers 0 to 2. The address number of an LU is referred to as the logical unit number (LUN). When HP StorageWorks Continuous Access XP and other optional features manipulate LUs, they use LUNs to specify the LUs to be manipulated. You can add, change, and delete LU paths when the system is operational. For example, if new disks or server hosts are added to your disk array, you can add new LU paths.
LU 00:00 (LUN 00). One path comes from the CL1-N port and the other path comes from the CL1-Q port. Thanks to this two path configuration, hosts can access the user LU even if one of the paths fails. Figure 2 LU paths configuration in a NAS environment Notes: • In a NAS environment, up to 256 LU paths can be defined for one NAS port. • In a NAS environment, you cannot define LU paths to logical volumes unless they have the Read/Write access attribute.
load balancing among processors, there is no reason not to use both ports in the I/O path of one processor or to use both ports in the I/O path of a processor. Figure 3 16-Port CHIP pair labeling Port numbering is as follows: Cluster 1 uses CL1-* and CL3-*, while Cluster 2 uses CL2-* and CL4-*, where * is an alphabetical character designation of the port such as A, B, C, and so on. Ports A, for example, CL1-A and CL3-A, share the same processor for I/O purposes.
Figure 5 Host group example 2 LUN Manager can define paths between a single host and multiple LUs. In Figure 5, 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. Hosts can be members of only one host group for a given port. Host group definitions and members apply only to the port that they are defined for. Host modes As part of registering hosts in host groups, you will be asked for the host mode.

For Windows with any FC HBAs when MSCS is not needed.
In Figure 6, 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 6 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 the Fibre Channel topology 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.

If high-speed (2 port) mode is applied to a four-port channel adapter board, two ports out of the four ports cannot be used. The remaining two ports can exclusively use channel processors and FOPs that would otherwise be reserved for the other two ports. Figure 7 Differences between high-speed and high-speed (2 port) modes Before changing the configuration of a port that is being used, perform a backup operation. You cannot switch between standard and high-speed while you are online to the hosts.
• iSCSI name: (Mandatory). You must assign iSCSI names to iSCSI ports. iSCSI names are used to uniquely identify each iSCSI node. iSCSI nodes are devices that use the iSCSI protocol for communication, such as iSCSI ports in the disk array, host bus adapters in host servers, and switching hubs for network relaying. iSCSI names must be specified in one of the following formats: • eui format: An IEEE 64-bit Extended Unique Identifier is used to specify the iSCSI name. The iSCSI name begins with eui.
responds to the ping command, the host and the XP128/XP1024 can communicate with each other. See ”Checking the status of connection between hosts and the disk array (iSCSI environment only)” on page 49. User authentication (iSCSI environments only) When configuring an iSCSI environment, you can use LUN Manager to set ports of the disk array to authenticate hosts. In an iSCSI environment, the ports use CHAP as the authentication method.
Host authentication When a host attempts to connect to the disk array, the connection results of the host’s authentication depend on the port settings. Figure 8 illustrates the relationship between port settings and the connection results. Figure 8 Flow of port authentication Each case in Figure 8 is explained below.
CAUTION: If a host uses Microsoft iSCSI Initiator and is configured for port authentication using CHAP, host authentication will fail. To allow such a host to connect to the port without authentication, do not configure it for port authentication using CHAP. NOTE: You must register user information of all the hosts to be connected to a port on which host authentication is performed.
The user information of Host C is not registered on port 1. When Host C tries to connect to the disk array, authentication fails and the connection request is denied. Host D is attached to port 2, which does not authenticate hosts, so Host D can connect to the disk array without authentication. In this case, it does not matter whether the user information of Host D is registered on port 2.
LU Path tree The LU Path tree on the upper left of the LUN Manager tab lists the Fibre Channel and NAS ports in the disk array and hosts connected to them. Hosts are identified by nicknames and WWNs and are classified by host groups. The LU Path tree may contain different folders: Fibre Channel, NAS, iSCSI, and so on.
The following are the NAS port icons used in the LU Path tree: Table 7 Icon NAS port icons for LUN Manager operations Status Indicates that you can assign paths from this NAS port to logical volumes Represents a short-wave port in standard mode with LUN security 30 LUN Manager for the XP128/XP1024
When you double-click a NAS port, the following host groups appear: • NAS-Sys • If you select NAS-Sys, the table on the right displays information about paths to system LUs. The table contents are dimmed and cannot be changed. • This host group number is 00. • User • If you select User, the table on the right displays information about paths to user LUs. • This host group number is 01.
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. The table contains the following information: • LUN: LUNs (address numbers) assigned to LUs, which are LDEVs that can be accessed by hosts. If no paths are defined, the other table columns are blank. The following icons indicate status.
The tables contain 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 (Nick Name in iSCSI Name table): Indicates nicknames for hosts. Nicknames can be specified in the LUN Manager pane. • The WWN (WWN table only). Each worldwide name represents one host.

2 Volume Management for the XP128/XP1024 Use Volume Management to perform the following tasks: • ”Volume Management (LU Size Expansion)” on page 59) • ”Volume Size Configuration (VSC)” on page 60) 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 28 shows the effect of a LUSE configuration.
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. • The maximum capacity of a LUSE volume is 2 TB for XP128/XP1024 arrays.
• Install CV: Creates custom volumes from free space. • Make Volume: Converts a custom volume back to a normal volume (VDEV). The Make Volume function clears all custom volumes under a VSC volume and creates an initial volume (VDEV) that consists of new user-defined custom volumes. The Volume Initialize function uninstalls all custom volumes under a VSC volume, and reformats the VSC volume as a normal volume (VDEV). Compared to other emulation types, use OPEN-V to easily create volumes of any size.
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. Each VDEV in a parity group has the same configuration, and is assigned the same FVs of the same size and RAID level. VSC functions (Volume to Space, Install CV, Volume Initialize, and Make Volume) are performed on each VDEV. VDEVs are also separated from each other by the boundary limitation. You cannot define a volume across two or more VDEVs beyond the boundaries.
Restrictions • The LDEV must not have a path definition, including TrueCopy (TC390), Continuous Access XP, ShadowImage (SI390), Business Copy (BC), and Continuous Access XP Journal pair volumes. • The LDEV must not be a component of a LUSE volume. This applies to all supported emulation types except for OPEN-V. • The LDEV must not be reserved for Auto LUN. • The access attribute must be set to Read/Write.
As defined in Table 19, 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 19 VSC supported emulations Emulation Can create these volume size configurations OPEN-3 3, 8, 9, E OPEN-8 3, 8, 9, E OPEN-9 3, 8, 9, E OPEN-E 3, 8, 9, E OPEN-V V Table 20 lists specifications and the minimum and maximum volume capacities for mainframe and open systems.
Table 21 Capacities of open system custom volume sizes (continued) Setting size (MB) User size (MG)1 Notes 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 13893.04688 Maximum OPEN-E volume size 737256 737256.09375 Maximum OPEN-V volume size (maximum VDEV volume size) 1. The term user size refers to capacity available to users.
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 33 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).
• Emulation: The emulation type of the LDEV. If the selected LDEV is a VSC volume, the emulation type is displayed together with CVS (for example, OPEN-3 CVS). If the selected LDEV is a LUSE volume, the emulation type is displayed with an asterisk and the number of volumes in the LUSE volume (for example, OPEN-E*5).
• PG: A combination of the disk group and the parity group. If the LDEV extends over two or more parity groups, the PG column displays the smaller parity group number. A parity group number that starts with a letter E indicates that the parity group consists of one or more external LUs (for example, E1-1). • CLPR: The cache logical partition (CLPR) number and name. The CLPR number consists of two digits. The CLPR name consists of up to six characters.
If you select a LUSE volume as the top LDEV, the Volume Count list is unavailable, and step 3 cannot be performed. In this case, select the LDEVs in the Free LDEVs table and click Add. To delete LDEVs, select the LDEVs in the Expanded LDEVs list and click Delete. 3. In the Volume Count list, select the number of LDEVs that should form a LUSE volume. The Expanded LDEVs list displays as many LDEVs as specified in the Volume Count list.
Creating a LUSE volume using the LDEV information table CAUTION: Creating a LUSE volume destroys existing data. To protect your data, make a backup copy of the existing data before starting the LUSE creation operation. 1. In the Volume Management pane, select a CU number in the LDEV Information tree. 2. In the LDEV Information table, select the normal LDEVs, VSC volumes, or LUSE volumes. Right-click the selection and select Set LUSE Volume. a.
If the XP disk array has firmware version 21.06.22 or later installed, you can reset an unregistered LUSE volume to the state before it was created. However, you cannot recover any LUSE volumes that have been released already to the state when they were created.
The status of each parity group is indicated by one of the following icons. Table 24 Parity group status icons Icon Status Parity group Set of concatenated parity groups The status of each VDEV is indicated by one of the following icons. Table 25 Icon VDEV status icons Status No pending VSC actions VSC actions have been stored, but not yet implemented on the subsystem Parity Group - LDEV table This table shows information about volumes in a VDEV selected in the Parity Group - LDEV tree.
Volume status (continued) Table 27 Status Description Format Volume is being formatted. Correction Access Volume’s access attribute is being changed. Copying Volume’s data is being copied. Read Only Hosts can only read the volume. Hosts cannot write any data to the volume. Unknown System does not recognize the volume’s status. Capacity unit list The Capacity Unit list allows you to select the unit (MB, Cyl, or block) to display for volume capacity.
2. Select one or more LDEVs (normal or custom volumes) you want to convert to space. For the OPEN-V emulation type, LUSE volumes can also be converted into free space. If the available LDEV is a LUSE volume, the emulation type is displayed together with an asterisk and the number of volumes in the LUSE volume (for example, OPEN-V*3) in the Emulation column of the table. To select two or more consecutive LDEVs, click the LDEVs while pressing the Shift key.
If the VDEV you selected is not an OPEN-V volume, the Install CV pane (1) for non-OPEN-V appears (Figure 36). Go to step 4. Figure 35 Install CV pane (1) for OPEN-V (when two or more free spaces are available) Figure 36 Install CV pane (1) for other than OPEN-V 3. From the Install CV pane (1) for OPEN-V, do the following: a. In the Capacity Unit area, select MB, Cyl, or block for the capacity unit.
b. Select one of methods by clicking Specify capacity and number, Divide free space by number, Divide free space by capacity, or Set remaining space as volume. NOTE: If there are two or more free spaces in the VDEV, only the Specify capacity and number option is available. c. Specify the capacity of the volume and/or the number of volumes according to the selected method.
The Install CV function allocates custom volumes in the order in which the function finds free space sufficient enough to hold them. Allocate custom volumes in descending order of capacity for optimum space allocation. c. Click Set. The pane displays the selected custom volumes. Figure 38 Install CV pane (1) for other than OPEN-V after clicking Set d. Repeat step 4a through step 4c to create additional custom volumes. e. To delete a custom volume, click the custom volume, click Delete, and then click OK.
5. After configuring custom volumes, click Next. The Install CV pane (2) is displayed. Figure 39 Install CV pane (2) Use this pane to assign the CU and LDEV numbers of a custom volume to be created. The top area is the CV setting information area and shows detailed information about the custom volumes to be created. 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 created. 6.
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 priority group does not belong. When the check box is cleared, you can only select the number of an LDEV in the SLPR to which the parity group belongs.
If the boundary area of the selected LDEV number has an SSID, the Install CV confirmation dialog box is displayed. Go to step 15. Figure 41 Setting the SSID 13.In the SSID setting area, select a CU number to assign an SSID to, enter a new SSID in the Input SSID box, and click Set. The SSID is displayed in the SSID box of the SSID setting area. Repeat this step until all the SSIDs are set. NOTE: You can enter the SSID only when logged in as a user in the StorageAdmin group with full array access.
15.Verify that the information in the Install CV confirmation dialog box is correct, and click OK. The Customized Volume screen is displayed with the new settings in blue. Figure 42 Customized volume screen 16.Click Apply. a confirmation message appears. 17. Click OK. The custom volume is created. A dialog box appears when the requested action is complete. 18.Click OK.
2. Right-click any part of the Parity Group - LDEV tree and select Make Volume. The Make Volume pane (1) appears. Figure 43 Make Volume pane (1) 3. From the Make Volume pane (1), do the following: a. In the Capacity Unit list, select MB, Cyl, or block for the capacity unit. b. Select one of methods by clicking Specify capacity and number, Divide free space by number, Divide free space by capacity, or Set remaining space as volume.
d. Click Set. The pane displays the setting in the table. Figure 44 Make Volume pane (1) after clicking Set e. To set other custom volumes, repeat step 3a through step 3d. f. To remove a setting, select the custom volume, click Delete, and then click OK. To remove all settings, click Clear, and then click OK. 4. After setting all custom volumes, click Next. The Make Volume pane (2) appears.
NOTE: If no CV is set, the Make Volume operation does not create a volume in the VDEV. In this case, a message appears and the Volume Management pane appears. Figure 45 Make Volume pane (2) Use this pane to assign CU and LDEV numbers to the custom volumes to be created. The top area is the CV setting information area and shows detailed information about the custom volumes to be initialized.
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.
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.

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.
Formatting all blocked volumes Use the All Format pane to format all blocked volumes in parity groups in the local disk array and/or external disk array. This pane contains the following: • Parity Group Type: Volumes to be formatted. • All Type: Formats blocked volumes in all parity groups in the local and external disk arrays. • Internal PG: Formats blocked volumes in all parity groups in the local disk array. • External PG: Formats block volumes in all parity groups in the external disk array.
