Problems with HP surestore DAT 72 drive, here's what happened:
Drive died (/dev/st0)
Removed drive
Rebooted
Drive no longer shows up in /dev/st0 or /proc/scsi/scsi
If you've removed the drive and rebooted, of course the drive won't show in
/proc/scsi/scsi, or as /dev/stX. There's nothing there to be scanned so there's nothing
there to show.
/sbin/lsmod shows that the drivers are still loaded
But the st driver only creates entries in /dev/ for tape devices which are connected and
turned on (i.e. reply to SCSI INQUIRY).
Is there a way to rescan the scsi bus?
Yes.

If the device doesn't show in /proc/scsi/scsi do I need to recreate the
device?
No, the devices (/dev/st) are created by the st device driver. Entries in /proc/scsi/scsi
are created by the SCSI driver when it scans the SCSI bus. After connecting the drive, you
rescan the SCSI bus. You may need to reload the st kernel module, not sure, it's a while
since I've tried anything like this.
