hey folks
we've been getting scsi errors during tape backups using dump.
most of the time the backups complete without any problems
but once every 20-30 or so runs
we get an error like the one bellow
we are running
dell poweredge 2600 with powervault 114t LTO2 tape drive
FreeBSD 5.4-RELEASE-p7 FreeBSD 5.4-RELEASE-p7 #2: Fri Oct 7 22:49:12
EDT 2005 i386
bellow is the error
and some other handy info (let me know if this isn't enough)
