Detecting New SAN LUN in RHEL5

[Young, Mike]

I'd like to rescan the fiber card rather than rebooting.  Since RHEL5 doesn't require you to load the drivers of the vendor, none of the tools (lun_scan, et al) are installed either.  There must be a way of detecting new LUNs without rebooting - everything else has been pretty automatic so far (card detection, activation, etc).

Did you rescan the SCSI/FC controller?  Or reboot the machine?
