[ILUG] How do I map fibre channel to absolute /dev/sgxx

[Patrick Tuite]

Hi all

I had a bit of a problem with a fibre channel tape library. We recently moved 
a bunch of systems, some connected to a fibre channel switch with the tape 
library & storage arrays and discovered when running scripts for Amanda that 
the tape library media changer, previous mapped to /dev/sg6, had changed 
to /dev/sg1. All the cabling was marked and reassembled identically.

I was wondering if anyone knew a quick way to map the SCSI ID for a device to 
a particular block device id when the system boots to avoid having to edit 
the scripts each time it may change if the systems are ever restarted?

Thanks

Patrick
