[cumbria_lug] Rescan SCSI RHEL

[Malcolm Logan]

I have a bunch of blade servers attached to a SAN via SCSI. They are all
running RHEL. Part of the backup procedure I am working towards involves
using the SAN to create snapshots of the LUN's, mounting these snapshots to
a server, and then backing those snapshots upto to tape.

But I don't know how to present and mount a LUN without rebooting the server
you are mounting it to. I have over 100 LUN's to back up every night and
therefore need to know someway of rescanning the SCSI bus to mount these new
LUN's.

Any ideas anyone?
