2 disks in raid 1 displaying imminent hdd failure

[Az_7]

Hi,

What would be the correct procedure for replacing hdd's displaying imminent failure if both drives are in the same raid 1 set?

[Jørgen Olesen]

Replace one disk, then wait until the disk is syncronised and then replace the other disk.

Thanx. This is what i did, however the raid set does not rebuild & displays "waiting to rebuild" message. Changing rebuild priority does not make any difference.

You're doing it right. I think there may be something preventing the rebuild since both drives are showing imminent failure - I have tripped across that before.

I hope you have this pair backed up. Is it an OS disk or "just" a data area? I'm thinking you just might have to backup, swap BOTH disks, create mirror set and array, restore.

Hi,

If your controller and disk firmware, drivers and array applications (i.e. ACU) are at the latest supported versions and you still can't get it rebuild, try to get an Array Diagnostic Utility report (if your platform supports it) analyzed to see what the reason(s) are. Your only other option is to recreate and restore from backup.

FWIW: Usually having everything current will prevent these issues.

Tx for the feedback. Ended up restoring from back up.

Hi,

I suggest you update your controller & disk firmware and drivers to help reduce the chance of this happening again.
