2012-11-27 12:41 PM
we received an alert for disk failure on one of our netapp box with below details. I checked from system manager and found the disk status is Un-owned. just want to know what does this un-owned stands for. is the disk replaced or its corrupted.
There are one or more failed disks.
Disk on adapter 2b, shelf 15, bay 16, failed.

Un-owned simply means that the disk has not been assigned by software based ownership. Each system has a unique id and when a disk is added it gets assigned to a system. In some cases because of configuration or whatnot a disk will not be assigned and will show the status you mentioned. You can use the command 'disk assign <disk id>' and assign it to the system that you would like.
If you have a system with mixed drive types (FC & SATA) then you probably want to assign disks manually. But if you have a system of dedicated disks you can enable the option 'disk.auto_assign' to automatically add disks when added.
Having a disk unassigned doesn't hurt the system and it's not a bad thing by any means.
