ONTAP 9 Manuals ( CA08871-402 )

You can view disk ownership to determine which node controls the storage. You can also view the partition ownership on systems that use shared disks.

You can select a non-default policy for automatically assigning disk ownership or disable automatic assignment of disk ownership.

If your cluster is not configured to use automatic disk ownership assignment, you must assign ownership manually.

You can set the ownership of the container disk or the partitions manually or by using auto-assignment—​just as you do for unpartitioned disks.

A disk that has failed completely is no longer considered by ONTAP to be a usable disk, and you can immediately disconnect the disk from the shelf.

ONTAP writes disk ownership information to the disk. Before you remove a spare disk or its shelf from a node, you should remove its ownership information so that it can be properly integrated into another node.
