[daip] error with DAT and FITTP

[Kevin Healy]

Hi,

I'm trying to write some data onto a DAT tape using FITTP.  I am getting the
following errors:

yso.la> FITTP1: Task FITTP  (release of 31DEC04) begins
yso.la> FITTP1: Writing to tape drive number   1
yso.la> FITTP1: Writing at current tape position
yso.la> FITTP1: Writing beginning-of-write EOFs
yso.la> FITTP1: ZTAPE: LUN128 IO ERROR AT   1 OP OF BEGW SYS ERR CODE 0005
yso.la> FITTP1: ZERROR: IN ZTAP2 ERRNO = 5 (Input/output error)
yso.la> FITTP1: ERROR     3 BEGINNING WRITES WITH EOFS
yso.la> FITTP1: Purports to die of UNNATURAL causes
yso.la> FITTP1: yso          31DEC04 TST: Cpu=       0.0  Real=     420

I am using the following inputs:

The machine is a PC architecture workstation running RedHat Linux 7.x.  The
DAT drive is connected by a SCSI bus.  I haven't had any previous problems
with this distribution and yesterday I successfully FITTP'd another dataset
to tape using the same drive.

I have now cleaned the drive with a cleaning tape.  I've also tried
two different tapes, just in case I was dealing with a bad tape.

Any help in diagnosing this issue would be greatly appreciated.

				Thanks,
