Has anyone tried putting more than 8 small dumps (20meg~50meg each) onto a
single 8mm tape over a period of 8 days ?
I tried appending the 9th dump (about 20meg) today and got barfed at by
the Exabyte.
The machine with the exabyte drive is called cognito and the machine that
I want to dump from is called clarity. Both machines are running SunOS
4.0.1. cognito is a Sun-4/260 with a local scsi disk (327meg) and a local
1/4-inch cartidage tape drive and clarity is a Sun-4/280S with an Eagle
and a Hitachi. The Exabyte device drive I'm using on cognito is from
Apunix.
Here is what I've done.
==========================================
cognito-root(2)-[/]: mt -f /dev/rxb0 rew
cognito-root(3)-[/]: mt -f /dev/nrxb0 fsf 16
cognito-root(4)-[/]:
clarity-root(9)-[/]: dump 0unsf 14500 cognito:/dev/nrxb0 /dev/rxy1f
DUMP: Date of this level 0 dump: Mon Aug 28 15:04:50 1989
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rxy1f (/spare) to /dev/nrxb0 on host cognito

DUMP: write: I/O error
DUMP: write: I/O error
DUMP: Tape write error 26 feet into tape 1
DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no") no
DUMP: The ENTIRE dump is aborted.

==========================================
Here is the message I found on cognito:/var/adm/messages :-
==========================================
Aug 28 15:05:12 cognito vmunix: xb0: SCSI device error cs=c0<CC,ERR> ss=0x2 (check \condition) ds=5 (illegal request)
==========================================
Does any know what kind of error is that ? Is it because I haven't cleaned my
drive ? I hope that it is nothing serious though.
Any pointers will be much appreciated.
