You can delete a host object from the Deleting Hosts panel.
A deletion fails if there are any virtual disk (VDisk)-to-host mappings for the host. If you attempt to delete the host and it fails due to the existence of VDisk mappings, you are presented with the opportunity to perform a forced deletion, which deletes the VDisk mappings before the host is deleted.
This task assumes that you have already launched the SAN Volume Controller Console.
When you delete a host object, all active ports are added to the Available Ports list.
