Once again, we are experiencing errors with our DAT drive. We've got one
drive in the shop and now the other one is giving errors. There are both
HP C1533A DDS-2 tape drives.

Logged the following error when performing
> /sbin/vdump -0Cuvf /dev/nrmt0h /u > /var/adm/backup/vdump_u.log

> tail -f /var/adm/backup/vdump_u.log
