Quick & Dirty: Replacing NetApp Disk

This doesn't include steps for a MetroCluster, I'll add that later if I do that

1.      Verify failed disk
SnapVault> vol status -f shows failed disks

  also, 
  SnapVault> disk show 0a.02.03
 Shows failed disk  
    where 02 is the shelf , see LED number on front, left (shelf 1 is top, 2 is middle, 3 is bottom)
    where 03 is bay (see printed numbers associated with each disk location)

The disk is amber instead of green and the shelf indicates a fault as well.  To make the disk blink to be sure it's the correct one, run

SnapVault> priv set advanced
SnapVault*> blink on 0a.02.03
SnapVault*> blink off 0a.02.03

2.       Now you need to physically replace disk

3.       Assign the newly replaced disk so it becomes a hotspare:

SnapVault> disk assign 0a.02.03

4.  Verify all is well

SnapVault> disk show 0a.02.03
    to verify it's assigned as spare
SnapVault> vol status -f shows failed disks
 Note: OnCommand GUI can do some of this too under "Storage", "Disks"
