Hi guys,

I need to connect a server to our tape library over a fibre HBA. The HBA was automatically detected by Redhat, luckily, as drivers and utilities aren't yet available from the HBA vendor as yet for Redhat 4.

Here's what comes up when I do a dmesg (bold print is relevant):

SCSI subsystem initialized

And when I do an lspci:

07:06.0 Fibre Channel: Emulex Corporation LP10000 Fibre Channel Host Adapter (rev 01)

Bacula, the backup software I'm using just needs to address the tape unit using a /dev/xxx device. How do I set it up so the tape unit appears in /dev ?

Thanks guys.

The first scsi tape device should always be /dev/st0, then /dev/st1, etc... The library should show up as a scsi generic device, probably /dev/sg0. 'cat /proc/scsi/scsi' will show you what devices you have attached, but it won't show you their device names. Also make sure the st and sg modules are loaded 'modprobe st ; modprobe sg'.

Here are a few commands to help you figure out whats what. You'll need to stop both the bacula-sd and bacula-dir daemons to have access to the devices.

mt -f /dev/st0 status
mtx -f /dev/sg0 status
