34 LUN Manager for the XP1024/XP128
Associating host groups to logical volumes
You can use LUN Manager to define LU paths by associating host groups to logical volumes. For
example, if you associate a group of three hosts with logical volumes, LU paths are defined between the
three hosts and the logical volumes.
1. In the LU Path tree on the LUN Manager main pane, select a host group.
2. In the CU list above the LDEV table, select a CU number. The LDEV table shows LDEVs in the CU.
3. In the LDEV table, select one or more LDEVs. Press the Ctrl key to select multiple LDEVs.
4. In the LU Path table, select the LUs.
5. Click Add LU Path. A dialog box prompts you to confirm the LU Paths to be defined.
6. Click OK. The settings are shown in blue in the LU Path table.
7. Click Apply in the LUN Manager main pane. A confirmation message appears.
8. Click OK. The settings are applied to the disk array.

Deleting LU paths
1. In the LU Path tree on the LUN Manager main pane, select a port.
2. In the LU Path table, select one or more LUNs to which LDEVs are assigned (If an LDEV is assigned to
a LUN, the columns to the right of the LUN column are not empty).
3. Right-click the selected port and select Release LU Path. A dialog box displays information about the
LU paths to be deleted.
4. Click OK. The settings are shown in blue in the LU Path table.
5. Click Apply in the LUN Manager main pane. A confirmation message appears.
6. Click OK. The settings are applied to the disk array.
Changing the name and host mode of a host group
Before changing the host mode of a host group, back up the data on the host group’s port. The operation
for changing host mode should not be destructive, but data integrity cannot be guaranteed without a
backup.
To change the host mode for host group 0, port security can be enabled or disabled. For all other host
groups, you must enable port security before changing the host mode.
1. In the LU Path tree on the LUN Manager main pane, right-click the host group and select Change Host
Group. The Change Host Group dialog box appears.
Figure 17 Change Host Group dialog box
NOTE: After you select the Option button, the pane expands to display check boxes. The check
boxes are numbered sequentially from left to right. The left-most check box on the upper row is #0,
and the check box immediately to the right is #1, and so on. The numbers indicate option
numbers; select check box #0 to select option #0.
2. To change the name of the host group, enter a new name in the Group Name box.
