[Linux-ia64] Problem to write a tape ..

[Jean-Philippe BATTU]

Hi

I am trying to do some backups on an old exabyte 8505XL
on my IA64 system running with redhat 7.2

My device is the only one device on the scsi chain. I have
a terminator on this chain.

I can write little files (tar cvf /dev/st0 /etc/passwd) but
when I write large files (dump 0f /dev/st0 /dev/sda3) I get an
error on the dump or tar command :

  DUMP: estimated 3323762 tape blocks.
  DUMP: Volume 1 started with block 1 at: Thu Oct  3 10:42:06 2002
  DUMP: dumping (Pass III) [directories]
  DUMP: dumping (Pass IV) [regular files]
  DUMP: write error 49000 blocks into volume 1: Input/output error

with on the log message files :
 kernel: st0: Error 27070000 (sugg. bt 0x20, driver bt 0x7, host bt 0x7)

I encountered this problem on redhat 7.1 but the problem seems
persisted in redhat 7.2

I looked for some informations about this error messages but all
the documents I found where about the termination string, and all
is ok

Could you help me ?
Any suggestions would be greatly appreciated

Thanks

This won't be of immediate help, but just fyi: I'm using an old hp
surestore 6000 (DDS-2) tape drive to back up my i2000 (aka big sur).
Each backup is usually ~8GB in size and I haven't seen any problems so
far (I also use dump/restore).

Can't help with deciphering the error message.  I vaguely recall that
there may have been a problem with early versions of "dump".  The one
I'm using is 0.4b27/libext2fs v1.27 as shipped by Debian/ia64.
