I talked with a technical type on Tuesday and Wednesday. The Emulex person thinks it might be a (drum roll please) driver problem. The theory is that VMS does the "right" thing--timing out if there's no response from the drive after a decent interval. If anyone knows whether this theory is true, I'd appreciate hearing from you. (But hey--the person at Emulex who's the authority on the TC7000 is said to be out until March 23 getting some training, so the story may change soon.) -- UUCP: ..seismo!elsie!ado ARPA: elsie!ado@seismo.ARPA Elsie and Ado are trademarks of Borden, Inc. and Ampex.
