A disk reports reservation issues when the "disk assign" command is run to assign disk ownership

Applies to

  • Product Model: FAS3220
  • OS: Data ONTAP 8.1.2 7-Mode


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.

Running the disk show -v command displays that the disk in question has no owner but is still being reserved by a different system.

The 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.
