Disk is seen as partner by both Controllers after replacement.

Hello All


I have just replaced a failed disk (5c.23.11) in one of our FAS6210. The disk was owned by controller 1 at the time. Once the disk was replaced after a minute are so, the amber led comes on and the disk cannot be seen in the cLi (disk show, vol status -s / -f etc). Logged onto system manager and it shows as a partner disk on both controllers? There were 2 failed disks at the time. The first replaced ok. I have also tried 3 new disks.

 

 

NetApp Release 8.2.3P3 7-Mode

 

BIR-NETAPP01> disk show 1c.23.11                    -------------------->> (now labled as 1c.23.11)
DISK OWNER POOL SERIAL NUMBER HOME DR HOME

 

BIR-NETAPP01> disk show -n
disk show: No unassigned disks

 

BIR-NETAPP01> vol status -f

Broken disks (empty)

 

Controller1 disks

 

 

Controller 2 Disks

 

Has anyone see this before?

 

Cheers

Hi,

 

Before proceeding with the following commands, make sure that the disk in question is not currently in a RAID group. If it is, copy the disk to a spare disk with the following command:

:::> storage disk replace -disk <CDOT disk ID > -replacement <CDOT disk ID of spare disk>  -action start

Disable autoassign

Remove disk ownership 

Check if disk is unassigned.

Now assign owner to the unassigned drive manually

Turn on autoassign

Hi, sorry to say, this did not resolve the issue.

Hi Darren,

 

Have you tried to check whether the disk is visible at all in a sysconfig -a on either node?

If the disk is present there, try using the disk show -a to see if it shows up and what the owning serial number is.

It could be the disk is a refurbished one where the disk ownership was not removed fully.

I've not run into this specifically but maybe just start by removing the disk ownership from the "offending" disk and then assigning it directly to the correct node:

Good luck,

@xandervanegmond Many thanks, as you stated, the disk was a refurb and still had assignment to its old Filer. Using disk assign -f sorted the issue.
