CMMVC1465E The command failed because one or more partnered systems do not support expanding a
replicated volume.
Explanation
A replicated volume can be expanded if all systems partnered for replication of the
volume support expanding a replicated volume. Else, the command fails.
User response
Upgrade partnered systems if downlevel and do not support expanding a replicated
volume, or use this command to expand volumes which are not replicated.
