Add initiators to a host
You can add existing named initiators to an existing host or to a new host. To add an initiator to a host, the initiator must be
mapped with the same access, port, and LUN settings to the same volumes or volume groups as every other initiator in the
host.
1. In the Hosts topic, select 1 through 128 named initiators to add to a host.
2. Select Action > Add to Host. The Add to Host panel opens.
3. Perform one of the following:
● To use an existing host, select its name in the Host Select list.
● To create a host, enter a name for the host in the Host Select field. A host name is case sensitive and can have a
maximum of 32 bytes. It cannot already exist in the system or include the following: " , . < \
4. Click OK. For the selected initiators, the Host value changes from -- to the specified host name.
Remove initiators from hosts
You can remove all except the last initiator from a host. Removing an initiator from a host will ungroup the initiator but will not
delete it. To remove all initiators, remove the host.
1. In the Hosts topic, select 1 through 1024 initiators to remove from their hosts.
2. Select Action > Remove from Host. The Remove from Host panel opens and lists the initiators to be removed.
3. Click OK. For the selected initiators, the Host value changes to --.
Remove hosts
You can remove hosts that are not grouped. Removing a host will ungroup its initiators but will not delete them.
1. In the Hosts topic, select 1 through 512 ungrouped hosts to remove.
2. Select Action > Remove Host. The Remove Host panel opens and lists the hosts to be removed.
3. Click OK. For initiators that were in the selected hosts, the Host value changes to --.
Rename a host
You can rename a host.
1. In the Hosts topic, select an initiator that belongs to the host that you want to rename.
2. Select Action > Rename Host. The Rename Host panel opens.
3. In the New Host Name field, enter a new name for the host. A host name is case sensitive and can have a maximum of 32
bytes. It cannot already exist in the system or include the following: " , . < \
If the name is used by another host, you are prompted to enter a different name.
4. Click OK. The hosts table is updated.
Add hosts to a host group
You can add existing hosts to an existing host group or new host group.
The host must be mapped with the same access, port, and LUN settings to the same volumes or volume groups as every other
initiator in the host group.
1. In the Hosts topic, select 1 through 256 initiators that belong to a host that you want to add to a host group.
2. Select Action > Add to Host Group. The Add to Host Group panel opens.
3. Perform one of the following:
● To use an existing host group, select its name in the Host Group Select list.
● To create a host group, enter a name for the host group in the Host Group Select field. A host group name is case-
sensitive and can have a maximum of 32 bytes. It cannot exist in the system or include the following: " , . < \
4. Click OK.
