Instructions


Open an SSH connection on any node in the cluster and log in using the "root" account.
Get a list of snapshot names and IDs that contain locks: 
isi snapshot snapshots list -v|egrep 'ID|Name:|Has Locks'|grep 'Locks: Yes' -B2
     
Make a note of the names or ID numbers for the snapshot to unlock. Run the following command for each snapshot to determine the lock ID for the snapshot to delete: 
isi snapshot locks list <snapshot name or ID>

Remove all locks using the snapshot_name/ID and lock number from the previous command: 
isi snapshot locks delete <snapshot name or ID> <lock_ID>

At the confirmation prompt, type Yes to confirm deleting the snapshot lock.

Additional Information

IMPORTANT!

Snapshots with names that start with "SIQ" are SyncIQ snapshots.

Do not delete SIQ snapshots unless the ramifications are fully understood. Deleting SIQ snapshots resets the SyncIQ policy state, which requires a reset of the policy and potentially a full sync. A full sync could take many times longer than a regular snapshot-based incremental sync to complete.
