4 Using the LUN Manager GUI. HP XP24000/20000
HP XP24000/20000 LUN Manager is a software that allows you to configure and manage Logical Unit Numbers (LUNs) on XP24000 and XP20000 Disk Arrays. You can use it to define I/O paths from hosts to logical volumes, reconfigure LUs while the storage system is online to accommodate system configuration changes and optimize storage system performance, and apply security policies to logical volumes to protect data from unauthorized access.

LUN Manager window
When you launch LUN Manager, the LUN Manager window opens. Use this window to define
LU paths and apply LUN security to logical volumes.
Storage partition administrators can view information or perform the operation within only the allocated SLPR (storage management logical partition). For information on SLPR, see the Cache
Partition User Guide.

LU Path tree
Use this tree to find information about LU paths. When you select a host group from this tree, the table on the right displays information about LU paths associated with the selected host group.
If you double-click the Fibre folder in the tree, fibre channel ports in the storage system appear as icons. On the right side of each icon appear the port name, the port address, LUN security status, and the port attribute (that is, whether the port is an initiator port, a target port, an RCU target port, or an external port).
The Fibre folder is available only if the storage system contains a fibre channel adapter.

When you double-click a fibre channel port in the tree, a list of host groups appears. On the right of this icon appear the group number (G-ID) of host group, the host group name, and the host mode. For details of host modes, see Table 5.1.
When you double-click a host group in the tree, a list of host bus adapters appears. On the right of this icon appear the nickname and the worldwide name (WWN) of the host bus adapter.
Host bus adapters are adapters contained in host computers and are used as ports for connecting hosts and the storage system.
When you double-click a port for which LUN security is disabled to display a list of host groups, the host groups except for the first host group (that is, the host group 0) are unavailable.

indicates a LUN to which no LU path is defined.
LDKC number, CU image number, and LDEV number of a logical volume. These numbers are delimited by a colon (:).
If an LDEV number ends with #, the logical volume is an external volume.
If an LDEV number ends with V, the logical volume is a virtual volume for Snapshot.
If an LDEV number ends with X, the logical volume is a virtual volume for Thin Provisioning.
Identifier of a logical volume from the host. If a UUID is not specified, this column is blank.
When you set a UUID from a host, any character not contained in the ASCII character set is automatically converted to a blank space.
N/A is displayed if you assign a logical volume, which is assigned to an OpenVMS server host, to a server host other than OpenVMS, or if you assign a logical volume, which is assigned to a server host other than OpenVMS, to an OpenVMS server host.
When N/A is displayed, the UUID you set cannot be guaranteed. If you want to display a UUID instead of N/A, clear the UUID setting, and then set the proper UUID for a server host.
Emulation types for each logical volume (or logical device).
For LUSE volumes, an asterisk (*) and a number appear on the right of the emulation type. For example, OPEN-9*3 indicates that three OPEN-9 volumes are combined.
Size of each logical volume.
Disk array level for each logical volume.
If the logical volume is an external volume or a virtual volume, the Disk array column does not show the level, but shows a hyphen (-) instead.
When the parity groups are combined, an asterisk (*) and a number appear to the right of the Disk array level. For example, 5(7D+1P)*2 indicates that two parity groups are combined.

For LUSE volumes, an asterisk (*) and a number appear on the right of emulation types. For example, OPEN-9*3 indicates that three OPEN-9 volumes are combined.

If the logical volume is an external volume or a virtual volume, the Disk array column does not show the level, but shows a hyphen (-) instead.
When the parity groups are combined, an asterisk (*) and a number appear to the right of the Disk array level. For example, 5(7D+1P)*2 indicates that two parity groups are combined.
Names of parity groups. If the name begins with E, the group is an external volume group consisting of one or more external volumes.
If the name begins with V, the group is a V-VOL group consisting of one or more virtual volumes for Snapshot.
If the name begins with X, the group is a V-VOL group consisting of one or more virtual volumes for Thin Provisioning.
When the parity groups are combined, a combined parity group appears in the square brackets ([ ]). For example, 9-7[9-8] indicates that 9-8 is combined with 9-7.

Description
If you want to change settings for a port, select the port from this list.
The text box on the left shows the current data transfer speed for the selected port.
Use the list on the right to specify the data transfer speed for the selected port. If Auto is selected, the storage system automatically sets the data transfer speed to 1 Gbps,
2 Gbps, 4 Gbps, or 8 Gbps (Gigabits per second).
NOTE: If you are using 2 Gbps HBA and switch, set the transfer speed of the CHF port as 2 Gbps. If you are using 1 Gbps HBA and switch, set the transfer speed of the CHF port as 1 Gbps. If you are using 4 Gbps HBA and switch, set the transfer speed of the CHF port as 4 Gbps. If you are using 8 Gbps HBA and switch, set the transfer speed of the CHF port as 8 Gbps. However, the transfer speed of the CHF port cannot be set as 1 Gbps when the CHF is 8US. Therefore, 1 Gbps HBA and switch cannot be connected. If the Auto Negotiation setting is required, the linkup may become improper at server reboot. Check a channel lamp, and if it is blinking, remove and re-insert the cable to perform the signal synchronization and linkup.
When the transfer speed of the CHF port is set to Auto, the data might not be transferred at the maximum speed depending on the connected device. Confirm the transfer speed at the Host Speed displayed in the Port list when you start up the storage system, HBA or switch. When the transfer speed is not the maximum speed, select the maximum speed from the list on the right or remove and re-insert the cable.
The text box on the left shows the current address of the selected port.
Use the list on the right to specify the address of the selected port.
