John, Go to the HMC and do problem analysis on the PCHID to see if you are getting sequence errors. Possibly a bad cable or connection.

If the VSM5 box is connected to a director or a switch of some kind, then I suppose that the cable between switch and VSM5 could be causing the problems. The originator of this thread didn't say whether he'd tried all paths, or how the box is connected to his server (I was going to write CEC !!).

A problem was already opened with Sun. Now here is what they found. There is another shop with the exact same problem. It has only been seen when using FDR and a mix of VSM4's and VSM5's. If it creates one tape on a VSM4 then tries to create another on a VSM5 then it get's the error. So we've simply varied the VSM5 drives offline to this one system.

For VSM I have no clue, but perhaps they use this to report some condition in the VSM. -- Bruce A.
