Disk showing errors | How do I apply more spare disk

ARnetapp — Wed, 04 Jun 2025 13:14:20 GMT

Hi team
I've been getting some errors regarding this disk 0b.01.10 can someone help me identify what it means?
Is this disk going to fail, if so it shows I have no spare disk on this node. Will it fail once i add an additional disk
to this node?

rtfowommr01b> Disk show

0b.01.10 rtfowommr01b(1886747403) Pool0 WD-RSRASFEAS01 rtfowommr01b(1886747403)
************

rtfowommr01b> vol status -s

Pool1 spare disks (empty)

Pool0 spare disks (empty)

That does look like the disk is failing, but fixing blocks does happen from time to time. However keep in mind that you have Raid DP. (2 parity disks).

Does the partner node have any spares that you could reassign to the b controller?

Otherwise, the disk will fail, and NetApp support will ship a new one to you when it does and the drive will be replaced.

The disk just failed

How can i move a disk from the a controller to B?

A side shows

Spare disks for block checksum
spare 0a.00.23 0a 0 23 SA:A 0 SAS 10000 857000/1755136000 858483/1758174768
spare 0b.01.21 0b 1 21 SA:B 0 BSAS 7200 1695466/3472315904 1695759/3472914816

1) Open a ticket with netapp to replace the failed disk.

2) As far as the steps.

You need to disable disk auto assign.
Unassign the spare from controller A
Assign to controller B.
Re-enable disk auto assign.

Here's a good example vid. https://www.youtube.com/watch?v=hrYli6euxb4

Got ya. I would try and track down a replacement though if you can. You'll eventualy run out of spare.
