88 LUN Manager operations
• You cannot delete host group 0 (zero). To remove all WWNs and LU paths from host group 0, you
must initialize host group 0 (for more information, see ”Initializing host group 0 (zero)” on page 88).
1. Start LUN Manager. The LUN Manager pane (Figure 14) appears.
2. In the tree, right-click the desired group, and select Delete Host Group. A confirmation message
appears.
3. Do either of the following:
• To delete all WWNs and the host group, click Yes.
• To delete the host group but not the WWNs in the host group, click No.
4. Click Apply. A confirmation message appears.
5. Click OK. Settings are applied to the array.
Deleting iSCSI targets
NOTE: You cannot delete iSCSI target 0 (zero). To remove all iSCSI names and LU paths from iSCSI
group 0, you must initialize iSCSI group 0 (for more information, see ”Initializing iSCSI target 0 (zero)”
on page 88).
1. Start LUN Manager. The LUN Manager pane (Figure 15) appears.
2. In the tree, right-click the iSCSI target, and select Delete iSCSI Target. A confirmation message
appears.
3. Do either of the following:
• To delete all iSCSI names and the iSCSI target, click Yes.
• To delete the iSCSI target but not the iSCSI names in the iSCSI target, click No.
4. Click Apply. A confirmation message appears.
5. Click OK. Settings are applied to the array.
Initializing host group 0 (zero)
If you follow the procedure below, host group 0 (zero) is set to its initial state. This procedure removes all
WWNs from host group 0 and also removes all LU paths related to host group 0. This procedure also
changes host group 0’s host mode to Standard and initializes the host group name. For example, if you
initialize host group 0 for port CL1-A, host group 0’s name changes to 1A-G00.
NOTE: You cannot perform this operation on host groups for NAS ports.
1. Start LUN Manager. The LUN Manager pane (Figure 14) appears.
2. In the tree, right-click host group 0, which is preceded by 00, and select Clear Host Group. A
confirmation message appears.
3. Click Yes.
Host group 0’s host mode and host group name change in the tree. WWNs are also removed from
host group 0.
LU paths are removed from the table on the right of the tree. LUNs corresponding to the removed LU
paths appear in blue.
4. Click Apply. A confirmation message appears.
5. Click OK. Settings are applied to the array.
Initializing iSCSI target 0 (zero)
If you follow the procedure below, iSCSI target 0 (zero) is set to its initial state. This procedure removes all
LU paths related to iSCSI target 0. This procedure also changes iSCSI target 0’s host mode to Standard
and initializes the iSCSI target name. After this procedure, the iSCSI target’s name changes to its default
name.
