Hello all,
I'm doing a backup to a HP SureStore 2000 2GB DAT drive
attached to an Adaptec 2940 PCI SCSI adapter on a
FreeBSD 2.1 120MHz Pentium, from a remote machine on the
network.
A bare-bones listing of the script to perform the backup
is as follows:
find / -depth -print |
cpio -o -H newc -C 65536 |
gzip -c |
dd obs=64k |
rsh tapehost -l tape dd obs=64k of=/dev/rst0
The file ~tape/.rhosts on tapehost is okay. The backup
runs fine, until around 92MB is transferred, then the
following error messages appear on the console and the
backup aborts.
Anybody got any ideas what's wrong?
Kernel error messages:
st0(ahc0:3:0): NOT READY asc:4,1

ahc0: target 3, lun 0 (st0) timed out

Thanks for any help,
