Detecting New SAN LUN in RHEL5

[James Marcinek]

Couldn't one just run kudzu and let it discover the devices?

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?
