I have a very noisy SCSI DAT backup tape drive which, for peace of
mind, I leave turned off.  The problem is that I need to reboot (with
the tape drive turned on) -- in order for the kernel to probe the
device -- whenever I want to do a backup.

Is there a way to force a probe while the system is running (i.e. at a
time other than boot time)?

Alternatively, is there a way to configure the kernel so that the SCSI
DAT tape drive is always assumed to exist, rather than having it
probe()'ed for?  The hard drive is also a SCSI device, so the SCSI
interface AHA-1542C (I think) is found during boot-time probe, as is
the SCSI hard drive.
