#Aggregate undestroy and volume recover

As per decommission process, data aggregate was offline and destroyed issuing the offline and destroy commands.

After a while, due some data retrieval needed, is requested to try to recover,

While issuing the undestroy command:

CLU-CRS::*> aggr undestroy aggr1
"storage aggregate undestroy" is not supported.

As per seen in kb, this is a 7-mode command not matching with anyone in Cluster Mode.

Question is simple: Is there anyway to recover the data?

The disks are unzeroed:

CLU-CRS::*> storage aggregate show-spare-disks

If trying to create new aggregate , the system is warning about if done, the disks will be zeroed before to be added

Any hint?

To my knowledge, this can only be done for volumes, not aggregates. But I hope for you, I will be proven wrong.

no chance without engaging NetApp support. if you have a recent ASUP and know which disk had which RAID position, you could manually rebuild the RAIDtree and labels, but I wouldn't count on being able to recover data that way. You might want to engage a data recovery expert (like Kroll-Ontrack) as they might be able to help

As @barren marlin says - better call Kroll.
