Red Hat Bugzilla – Bug 151105
SCSI errors when using aic7xxx or aic79xx with external RAID array
Last modified: 2007-11-30 17:07:06 EST
Description of problem:
System basically becomes unusable when either module is loaded and connected to
an external RAID array. Array presents itself as a single SCSI ID with each 2TB
logical drive showing up as a separate LUN. Errors show up with different cards
and different cables, and only after about a minute's worth of stress testing
(I use bonnie++).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Load aic7xxx or aic79xx module
2. Start bonnie++
3. Wait and monitor /var/log/messages
Bonnie run to completion without error.

This bug can be closed. Was able to trace the problem down to a problem with
Adaptec. Dropping the speed to U160 and disabling packet transfers on the
U320-based card cleared this problem.
Thanks for the update.
