writing to Tape from ATLAS has been paused so we can reduce the number of tapes used for writing. We have reduced the number of tape drives used for writing to 4 drives (each capable of writing 200 MB/s) we can write 67 TB a day to tape and we have almost 400 TB to write from internal HPSS disk cache to tape. Can not reduce the number of drives any more

We having a problem staging files from Tape to dCache disks. dCache is not pulling files from the HPSS Cache and we are seeing a lot of bad dCache restore requests. We are investigating and actively trying to clear up the situation so that data can flow.

This problem was triggered by a large request on Saturday mid-day >200k files. Exact source of the request is under investigation
