We had a problem with one costumer where is has stripesets with 7 disks. Through uerf we were getting messages with the following cam string: Hard Error detected. Through uerf without options one can see which scsi bus, target id and lun id is failling. I saw in note 278 that there is a way of knowing wich port, target, lun is reporting errors. Neverthless, this note information pertains to HSZ40 controllers. So my questions are: 1) Are the byte positions the same in the HSZ50 case? 2) Is there a document which can help the diagnostic of failling disks interpreting the frame output of the uerf command?

stop using uerf. Get DECevent. DECevent will report more that you ever
thought you wanted to know aout hsz errors.

Even with DECevent, a hard error detected will still not give the
specific nature of the problem. Usually, the only way to find out
what caused the hard error is to have a terminal connected to the
hsz that has the unit on line at the time of the error. Using someting
like polycenter console manager is the only way to trap these hard
error condtions. Some of the causes of these type of errors are
a command timeout on a device between the hsz and the device, followed
by the hsz doing a bus device reset on its scsi bus that contained the
device. You may also want to get the latest cam_disk.o module for
unix. The latest patches, april 97, have enhanced error logging
to capture the intial error that caused the hard error.
Were there any other entries in the error log, immediately before the
hard error?
