Symptoms
On a NAS OS cluster system, NAS OS log is showing Unowned LUN. NAS OS disk CLI command is showing 0KB and CLI menu command option D. "Disk and Volumes" is showing disks with "-- no partition table".

Resolution
Check if this is a newly installed NAS OS cluster system with Quiet status (Displayed on cluster Head LCD panel).

Quiet status indicates this cluster head does not own any LUN (volume) and what is required is to Take all LUNs through LCD panel. LUN ownership (through LUN stamps) is required before they can be used.

- From the Head LCD Menu, select (C. Take All LUNs).
- Select "Yes"
- The LCD will display (Taking LUNs) followed by a message (Took n LUNs).
- Select "Exit" and the Head 1 is now in "Alone" State

"Take all LUNs" is one of the step in cluster setup and applicable
to both attached storage and gateway backend storage.
