That's (I think) is not an issue at least for Marc. Your drive has firmware revision 1823 and it needs an upgrade to revision 203C or better, and revision 243F seems to be Ok. At least we here have three Conner 1060S drives: two of them were upgraded and are Ok since that day, the third one is "1080 sold as 1060" (Sun-style drive with a small 80pin connector and an interface part) and seems to be Ok too, though without a heavy load. The person to speak about an upgrade is <Soenke.Behrens@conner.com> # 1542CF in my system. I modified the AHA driver to call panic() if it # timed out twice in a row. You may want this patch - I'll send it to # you if you want. # # Gary # -- With best regards -- Andrew Stesin. +380 (44) 2760188 +380 (44) 2713457 +380 (44) 2713560 "You may delegate authority, but not responsibility."
