LU Path tree, selecting the host from the WWN table, and then clicking Add WWN.
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. Start LUN Manager, and display the LUN Manager pane ( Figure 7 ).
2. In the LU Path tree on the LUN Manager main pane, select a host group.
3. In the CU list above the LDEV table, select a CU number. The LDEV table shows LDEVs in the CU.
4. In the LDEV table, select one or more LDEVs. Press the Ctrl key to select multiple LDEVs.
5. In the LU Path table, select the LUs.

3. 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).
4. Right-click the selected port and select Release LU Path. A dialog box displays information about the LU
paths to be deleted.
5. Click OK. The settings are shown in blue in the LU Path table.

7. 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. Start LUN Manager, and display the LUN Manager pane ( Figure 7 ).
