At times, it is necessary to migrate disk ownership from a controller to a partner controller. When the disk ownership has been removed from the controller, the
disk assign command is run to assign the disk ownership.
However, the command fails with the disk reporting reservation issues:
Ownership for disk 3a.31.16 (S/N 6SL68C9G0000B34002AD) cannot be changed because system??(ID 1911953589) currently owns the persistent reservation.
disk show -v command displays that the disk in question has no owner but is still being reserved by a different system.
disk show -v -z command will also display the ID number of the system that owns the reservation on the disk in the 'PRkey' field.
