First had to put the aggregate back on line.

Then off line the volume

third delete the volume

forth delete the aggregate, the issuse was in previous attempts the volume would not go off line, or delete.

Plus all the warning messeges, but since there were no other volumes on this aggregate, proceeded.

afsnetappcl::*> aggregate online afsnetapp01_SAS_aggr2

(storage aggregate online)

Aggregate online successful on aggregate: afsnetapp01_SAS_aggr2

I would not use the above mentioned procedure, as you can read in this KB article. Instead use this procedure.

If anyone still looking for this issue

The Resolution is simple, you must Disable and Delete vserver audit which removes all the auditing staging (MDV) volume

Only then you can offline,delete the aggregate.

The Staging Volume "MDV_aud..." cannot be put offline, deleted even in advanced priviliges

This has worked for me
