Re: ONTAP 8.3 Aggregate and volumes destroyed. Need to recover data.

Hello Xsalvia,

Protection against accidental volume deletion
Starting with Data ONTAP 8.3, new default functionality is available to aid in the recovery of
accidentally deleted FlexVol volumes.
After all nodes in the cluster are running clustered Data ONTAP 8.3 or later, a volume delete
request against a volume that has type RW or DP (as seen in volume show command output) causes
that volume to be moved to a partially deleted state. By default, it is retained in a recovery queue for
at least 12 hours before being fully deleted.

I know is a long shot but use the diag mode and check in the recovery queue
