Hello. I supervise a Vax 780 system running BSD4.2. Our disk drives consist of 3 SI 9766 (rm05 equivalents) and a si 9900 controller. we are utilizing the si suplied disk driver but otherwise our system is "off the tape". Periodically, our system just freezes. Until recently we fixed by rebooting. The other day someone tried hitting the controller reset switch. Lo and behold the disk driver initialized and the system picked up exactly where it left off. No user lost as much as a key stroke. can anyone explain this behavior? please no flames about the 9766. they were purchsed for political reasons and they are soon on the way out the door in favor of eagles. (but the 9900 stays.) responses to me ihnp4!mmm! boone david boone 612-733-2264

We have four SI controllers driving ten CDC 9766 disks on three systems, have had SI controllers and drives since 1979, (our first is marked ``Ford Aero Engineering Prototype'') and have never seen this problem. John Nagle
