Investigating failing tape transfers from RAL and elsewhere for CMS. Currently the finger is pointing at FNAL FTS which was recently upgraded. I did a test with CERN FTS on a subset of the same data and that has successful transfers where the FNAL FTS has none. The data is staging successfully from tape but then not being instructed by FTS to move to Echo (at least this is the current working theory). Steve Murray is looking at it. He says that FNAL FTS is mis-configured for Antares.

Also on tape failures - a few CMS tapes were 'disabled' this week (they were re-enabled by the script, but still caused significant failures). Is this happening more than normal?

Intermittent webdav SAM test failures in the last 2 days. Coincident with critical status on a number of gws: svc01/02, gw14/15 mainly.
