X marks the node that owns the disk. A dash (-) means no disk in place.
Disks in bay 0 and 1 (shelf 1 and 2) are SCSI Enclosure Services (SES) disks.
Note: Disk ownership is changed after the initial setup, or after adding
additional disks. Use the
disk assign
command to change ownership, and the
storage
disk show
command to determine which node owns which disk.
