Deleting a host group
Use this procedure to delete a host group.
If host group 0 (zero) is deleted, all WWNs that belong to host group 0 are deleted and all LU paths that correspond to host group 0 are deleted. The host mode of host group 0 becomes Standard, and the host group name is initialized. To remove all the WWNs and LU paths from host group 0, you must initialize host group 0. For details, see Initializing host group 0.
- If you plan to delete a host group that includes paths to LDEVs with the GAD reserve attribute, reduce the number of LDEVs in the host group to 100 or fewer before deleting the host group. Host group deletion might fail if the number of LDEVs in the host group is too large.
- When a port has a path defined for an LDEV with the GAD reserve attribute and you need to configure the port (delete a host group, set a command device, or change the host mode, topology, AL-PA, or transfer speed), the operation might fail if you configure more than one port at a time. For ports that have a path defined for an LDEV with the GAD reserve attribute, perform these operations on one port at a time.
