I've been having some problems with scsi errors and was hoping someone
would be able to help me figure out what they mean.
My scsi card is an Adaptec 1542C; the scsi drive is a Quantum Empire
Here are some representative errors:
Sep 18 21:51:00 moonglum kernel: scsi0 : resetting for second half of retries.
Sep 18 21:51:01 moonglum kernel: SCSI disk error : host 0 id 6 lun 0 return code = 18000002
Sep 18 21:51:01 moonglum kernel: Current error sd801: sns = f0 3
Sep 18 21:51:01 moonglum kernel: Raw sense data:0xf0 0x00 0x03 0x00 0x00 0x0a 0x42 0x0a 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
Sep 18 21:51:01 moonglum kernel: scsidisk I/O error: dev 0801, sector 2592
If anyone can explain to me how to interpret these I would be very grateful.
Originally these scsi errors showed up after the system had been
running a while. Later they started showing during the fsck of my
root partition; fsck would attempt to fix a problem, apparently
succeed, and then the boot would fail with scsi error. (Please
forgive the imprecise description.)
I booted using boot/root disks and tried to fsck the partition; the
fsck failed, after reporting a problem with a particular inode. If I
looked at that file, I got the scsi errors. Abandoning my attempt to
repair the filesystem in the belief that their was a problem with the
drive, I copied my essential data off the drive (from my /home
partition, but removing a number of files from various partitions in
Afterwards I ran badblocks on the offending partition, but it told me
there were no bad blocks. I then ran fsck, which fixed the filesystem
on the offending partition. Everything now seems fine, but I'm
wondering if there is actually a problem with the disk, and not sure
how to determine if there is.
