Environment: SS20 w/ Solaris 2.4, two tape drives: one Exabyte EXB-8200
8mm and one HP DDS-DC 4mm DAT.
All of a sudden, tape operations started failing with I/O errors,
mounted tapes sometimes don't get recognized (`mt' says "no tape
loaded or drive offline") and `tar' sometimes just hangs when writing,
apparently blocking in i/o wait, unkillable with "kill -9". This
happens with both tape drives; both drives used to work fine the day
The main thing I've changed on the system in this timeframe is that
I've installed a SPARCprinter SBus card (SUNW,nvone0) attached to a
SPARCprinter, and NeWSprint 2.5B plus most of the available NeWSprint
2.5B patches. Could this have anything to do with my tape trouble?
Here are some of the syslog messages I get:
Apr 8 22:12:51 pikas unix: Disconnected command timeout for Target 5.0
Apr 8 22:12:51 pikas unix: SCSI transport failed: reason 'timeout'
Apr 8 22:12:51 pikas unix: : giving up
Apr 8 22:23:25 pikas unix: SCSI transport failed: reason 'incomple
Apr 8 22:23:25 pikas unix: te': giving up
Apr 8 22:24:26 pikas unix: SCSI transport failed: reason 'incomple
Apr 8 22:24:29 pikas unix: te': retrying command
I've applied patch 102002-03 (SunOS 5.4: fixes to esp driver), but
that didn't help anything.
Any advice? Thanks in advance,
