Solaris zpool recovery

[RimBlock]

Hi,

I have a Solaris 11.1 box with a zpool made of 4x 1.5TB Seagate Barracudas.

The PSU of the das box failed and on bringing up the das with a new PSU and doing a zpool status I am told the pool is offline with IO errors.

Ok, sounds reasonable.

I cannot seem to bring the pool back online or mark it as good. There was most likely very little activity on the disks at the time of the PSU loss so I would have thought recovery should have been fairly easy.

Anything I can try to recover the zpool rather than having to destroy and recreate ?.

Note the drives are in the DAS and are seen although they may be in a different order due to a rack restack last night. The error was the same before the restack but some drives were listed as failed rather than unavailable.

Unavail means it can't find the disks - try and put them online or alternatively try a different RAID/mobo combination. The pool seems fine, it's because it can't communicate is the issue.

RAID toast, mobo toast or PSU toast
