Unassign volumes
Unassign volumes from hosts or host clusters if you no longer need I/O access to that volume from the host or host cluster.
About this task
Keep these guidelines in mind when you unassign a volume:
If you are removing the last assigned volume from a host cluster, and the host cluster also has hosts with specific assigned volumes, make sure that you remove or move those assignments before removing the last assignment for the host cluster.
If a host cluster, a host, or a host port is assigned to a volume that is registered to the operating system, you must clear this registration before you can remove these nodes.
The volumes that were unassigned are available for a new assignment.
Until the changes are configured on the host, the volume is still recognized by the host operating system.
