Domain Panic!!


We have got a domain panic error in TRU64 cluster nodes. Allofasudden we got the domain panic in 4 domains w.r.t. 2 disks.
Bu only one of the disk in the HSZ70 Cluster disk array is showing amber light.
But surprisingly nothing is shown in the failedset.

Re: Domain Panic!!

A disk error could have caused a metadata write error, leading to the domain panic. Fix the disk problems and then run "fixfdmn" against each affected domain.

Re: Domain Panic!!

Yes its a disk error.

But when you ask to fix the disk error.
Question is what are my options?

Re: Domain Panic!!

More than likely replacing them might be the only option.

You could try to reseat the disk(s) and run the HSZ70> run config command to see if they show up again or you may be forced to replace them if they still won't configure and have completely failed.

Re: Domain Panic!!

Yes the only disk which is showing amber light is completely failed. We assume so becauze we restarted the whole cluster nodes and the controller but still the amber light exists.
Moreover it contains 2 D-units D302/303.

Replacement is the only option it seems and restore the data.

Any more suggestions?
