[dm-devel] Rescan for new LUNs

That sounds more like what I am looking for. But I can not find the
script on my system or what provides it via "yum provides". I am running
RHEL 5.5.
 
We have customers that run an Application that needs to be up 24*7. They
some times need to add additional storage and when attached to a SAN
they would prefer not to have to take the Application down and reboot
the system just to make the new LUNs be seen by the system.

It's not an easy process.

The rescan-scsi-bus.sh script was added in recent RHEL5 updates, already
in old SLES. I guess it's becoming kind of a standard.

Hello: 
        What is the best way to cause the system to rescan for new LUNs,
other than rebooting?
