We've been having some trouble with some Wren IV drives under Ultrix 2.2, and have some conflicting information that I'm hoping someone can clear up/explain. Our last system adminstrator got the following information from the vendor we bought the drives from (all model 94171-300): 16 sectors/track 4 tracks/cylinder !? 9167 cylinders/drive !? consequently, that's how the drive tables in Ultrix have been configured. Because of the problems with *large* amounts of disk errors in the past few weeks, our current system adminstrator called CDC (I think) and got: 40 sectors/track 9 tracks/cylinder 1412 cylinders/drive which seem more reasonable figures. Can someone verify these numbers for me? Now, assuming that we've configured the drives to be 14% larger than they actually are (hey, virtual drives, how nice!), can someone tell me what Ultrix is going to do as the drives approach real capacity? I'm trying to help our sysadmin track down some bad behavior with our disks. Thanks for any help. I'd prefer email, but I'll take what I can get. -- Steve Wampler {....!arizona!naucse!sbw}
