Hi Nigel,
Thanks for your reply!
The SCSI device in question does work properly, smartctl -H reports the
drive is in good health, and smartctl -a shows fairly normal looking
output.
Error counter log:
Errors Corrected by Total Correction
Gigabytes Total
ECC rereads/ errors algorithm

bytes] errors
read: 1606774 0 4 0 0
33811.545 4
write: 0 0 0 0 0
5737.408 0
Except for the 4 Total uncorrected errors - it's been a while since I
last checked the health of this drive with smartctl though, so I'm not
sure whether those 4 errors could relate to the recent SCSI wierdness.
I'm going to run a smart long background test and see what that turns up.
Thanks for your help!
Cheers,
Grant

Hi all,
We enountered an unusual condition with the LSI SCSI drivers last
night - we got an "attempted task abort", followed by about 10
minutes of no messages (I wasn't logged in at the time but believe
the system was unresponsive), followed by several minutes more of
similar messages, repeated:
It looks to me like whatever the LSI device driver was attempting to
talk to is failing. The apparent sequence is that a SCSI command has
failed to work correctly (a read, by the looks of it), there is a SCSI
command abort followed by the device driver issuing Test Unit Ready.
The TUR either took 10 mins. or the device driver timed out after
10mins. Another read command then failed in a similar way, resulting
in the same sequence of events. At some point, presumably whatever was
attempting to read the device gave up and all went back to normal.
Does that device normally work ok? It might be going faulty, or there
might be a cabling or termination issue. I doubt it's a device driver
fault, it looks to me like a hardware read error/timeout issue,
followed by re-tries, and/or additional failed attempts.
If daytime TV made shows about computers, this one would be "When SCSI
devices go bad."
