Does anyone know what might be causing the following errors in 2 P90 systems?
System 1 is a news server (full feed), system 2 is a mail server and
shell access system. Both have Adaptec 1740's and Micropolis drives:
MICROP Model: 3243-19MZ Q4D Rev: HT02
The first also has a Conner 30540, the second a SCSI DAT drive.
Both seem to get large numbers of the same sort of errors, but the news
server has a tendancy to lock up roughly weekly, while the other can go
weeks at a time with no serious problems.
Since the errors come from all the SCSI devices, I'm guessing it's either
a cabling or driver problem. I doubt both controllers are bad, but we
are using long cheap SCSI cables. Anyone have any ideas? I'm
considering trying an NCR as a replacement since they're cheap and fast.
