Re: Got error: "StoreOnce error: Maximum device locks"

You're running too many concurrent streams from/ to the SO. It takes a while for the finished streams to release the locks. If you're running object copy or replication try to reduce the # objects in the session reading from the same cat store or if obj cpy to tape reduce the # tape drives or concurrency on them.

How many concurrent streams are you actually running? I usually see this kind of message when customers are object copying from SO to 3 or more tape drives with a high concurrency set and basically are overloading the cat store. Does that match what you are doing?

You can try to increase, from Storeonce side, the value of the “Devices per Initiator port” or “Number of Devices per Login”. The name depends of the StoreOnce version. 

Increase it to the max and try again the backup.
