Hi

How to remove the ownership from this two faied disks.

I have tried run below command, but the system come back the disk is in a different pool

netapp::> disk removeowner -disk 5.1.19

Error: command failed: Failed to remove the owner of disk "5.1.19". Reason: Ownership Remove request failed for disk 5.1.19. Reasonisk is in broken pool.

I also tried run 'disk unfail' without success

Can anyone help?
