All,
I have a Dell PE1900 with an internal DAT72 drive. The drive appears
to fail midway through a dump after detecting the end of tape and
prompting for a new one. There is no specific sequence in which it
fails. Sometimes it could be after the first tape or after the second
tape. Dumps will complete for weeks at a time with no issue then
suddenly fail. There are no logs with errors except for the
dmesg.boot file after a reboot, which fixes the issue. Before the
dump there are these two lines:
"ahd0: SCSI Cell parity error SSTAT3 == 0x2
ahd0: Missing case in ahd_handle_scsiint. status = 0"
I did a search and found this posting http://lists.freebsd.org/pipermail/freebsd-scsi/2007-February/002869.html
which suggests to upgrade the BIOS and any other firmware. I tried
this suggestion and updated the Dell BIOS from v2.0.1 to v2.3.1 and
the Base Management Controller firmware from v1.69 to v2.09 however,
the issue still occurs. Durning this time all other services such as
mail, samba, and nfs remain functional. The only service affected is
SSH. When you try to login after the failure occurs you receive "PTY
allocation request failed on channel 0." Thank you in advance for the
help. If you need anymore information let me know.
Steve
