Hi all,
I'm seeing a huge number of errors in /var/log/messages of the form:
Jul 17 20:54:14 bsd kernel: (da2:isp0:0:0:2): SYNCHRONIZE CACHE. CDB:
35 40 0 0 0 0 0 0 0 0
Jul 17 20:54:14 bsd kernel: (da2:isp0:0:0:2): CAM Status: SCSI Status
Error
Jul 17 20:54:14 bsd kernel: (da2:isp0:0:0:2): SCSI Status: Check
Condition
Jul 17 20:54:14 bsd kernel: (da2:isp0:0:0:2): ILLEGAL REQUEST asc:20,0
Jul 17 20:54:14 bsd kernel: (da2:isp0:0:0:2): Invalid command
operation code
Jul 17 20:54:14 bsd kernel: (da2:isp0:0:0:2): Unretryable error
This is on FreeBSD 7.0 with a slightly trimmed down kernel. I'm
running both the 'isp' and 'ispfw' drivers. I've got a QLogic QLA2200
card with a StorCase (Kingston) S10K102 (12-disk SATA-to-FC) SAN
device attached.
The second number of the "SYNCHRONIZE CACHE" line ('40' in the example
above) changes between 0, 20, 40, and 60. This occurs on all 5 disks
currently installed in the StorCase device. I'm using the device in
NRAID (non-RAID) mode and then using FreeBSD's ZFS.
The device seems to be working very well, as far as I can tell the
files are being written without error, but these messages are clogging
up /var/log/messages to the point where I can't see if other stuff is
going wrong.
Is there any straightforward way for me to fix the problem, or at
least suppress these errors? I would like to know if other major
errors are occurring, but these just don't appear to be useful.
Any guidance welcome.
thanks in advance!
regards,
-Nick
