Deleting host groups
You cannot delete the host group 0 (zero). If you want to remove all the WWNs and LU paths from the host
group 0, you must initialize the host group 0 (”Initializing the host group 0 (zero)” on page 27).
1. Start LUN Manager, and display the LUN Manager pane (Figure 7).
2. In the LU Path tree on the LUN Manager main pane, right-click a host group and select Delete Host
Group. A confirmation message appears.
3. Click Yes to delete the host group. The host group you specified is removed from the LU Path tree.
4. Click Apply in the LUN Manager main pane. A confirmation message appears.
5. Click OK. The settings are applied to the disk array.
Initializing the host group 0 (zero)
Initializing the host group 0 sets the group to its default state. This process:
• Removes all the WWNs from the host group 0 and all the LU paths related to the host group 0.
• Changes the host mode of the host group 0 to Standard and initializes the host group name. For
example, if you initialize the host group 0 for the port CL1-A, the name of the host group 0 will change
to 1A-G00.
1. Start LUN Manager, and display the LUN Manager pane (Figure 7).
2. In the LU Path tree on the LUN Manager main pane, right-click the host group 0 and select Clear Host
Group. A confirmation message appears.
