[flexbackup-help] dd freezes.

[Gregory M. <gma...@gm...>]

Hello All,

I have an ide tape drive. (AIX2) 35/90gb tape drive. When I run a backup job
I get several i/o errors. Here is a cutout of my syslog:

Apr  5 23:00:02 fs1 kernel: st0: Block limits 32768 - 32768 bytes.
Apr  5 23:00:02 fs1 kernel: st0: Error with sense data: Current st0: sense
key Illegal Request

Apr  5 23:00:18 fs1 kernel: st0: Can't set default block size to 0 bytes and
density ffffffff.
Apr  5 23:00:19 fs1 kernel: st0: Error with sense data: Current st0: sense
key Illegal Request

Apr  5 23:00:19 fs1 kernel: st0: Can't set default block size to 0 bytes and
density ffffffff.

I find that the dd command freezes up and I cannot even kill -9 the process.
(most likely because it is a kernel processes). Does anyone know why this
processess might be looking up. I have the feeling it has something to do
with ide-scsi.

Thank You,
Greg
