Was it used by MirrorView/Sancopy etc at some point when it was good ?

See if any drivers are listed from ;

naviseccli -h arrayspa getlun -messner lun# -stack

After executing Brett's command see if it shows any drivers for mirror view or any other replication.

If yes then try the below command.

naviseccli -h -user -password   -scope 0 mirror -Async|-sync -setfeature - off -LUN

HTH,

Sheron

I thought maybe this info might be helpful:

Thanks Sheron, even though these luns didn't have any drivers attached, I tried running your command and got the responses that the system doesn't have Mirror Sync or Asynchronous software installed (tried running it both ways). Any other thoughts?

Thanks Brett@s - no drivers listed though for either LUN.

That is correct

The logs tell me that they are offline. Is that correct?

Oh, this would need an EMC ticket, this will be elevated to engineering. You might require to capture KTCONs. Please contact clariion support.

The only nuclear option is to re-image the array. That message indications the Pool is off-line due to a metadata fault - engineering can try to fixed it, but even then it's not clear they could in this case.
