Chapter 8. Hosts 383
Removing a host cluster member
To remove a host cluster member, use the rmhostclustermember command, as shown in 
Example 8-45.
Example 8-45   Removing a host cluster member 
IBM_2145:ITSO-SV1:superuser>rmhostclustermember -host ITSO-VMHOST-02 -removemappings 
ITSO-ESX-Cluster-01
IBM_2145:ITSO-SV1:superuser>
In Example 8-45, the host ITSO-VMHOST-02 was removed as a member from the host 
cluster ITSO-ESX-Cluster-01, along with the associated volume mappings because of the 
-removemappings flag was specified.
Removing a host cluster
To remove a host cluster, use the rmhostcluster command, as shown in Example 8-46.
Example 8-46   Removing a host cluster
IBM_Storwize:ITSO-V7000:superuser>rmhostcluster -removemappings ITSO-ESX-Cluster-01
IBM_Storwize:ITSO-V7000:superuser>
The use of the -removemappings flag also causes the system to remove any host mappings to 
volumes that are shared. The mappings are deleted before the host cluster is deleted.
Note: To keep the volumes mapped to the host objects even after the host cluster is 
deleted, specify the -keepmappings flag instead of -removemappings for the rmhostcluster 
command. When -keepmappings is specified, the host cluster is deleted, but the volume 
mapping to the host becomes private instead of shared.
