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

1.0.9 SAS 10000 block 971.9GB 0B 1.09TB not zeroed
1.0.10 SAS 10000 block 971.9GB 0B 1.09TB not zeroed
1.0.11 SAS 10000 block 971.9GB 0B 1.09TB not zeroed

 

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

Any hint?

Hello,

 

Have you try to do it in maintenance mode?

 

I should have a 8.3 in my lab, I will check if i found something.
