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).

Hello,
What's the method for detecting newly allocated SAN LUNs in RHEL5? I supposedly have a LUN allocated, but I can't see it in /dev/cciss or /dev/sd*.
Thanks,
Mike.
Did you rescan the SCSI/FC controller? Or reboot the machine?
Rescanning the card (as mentioned in a previous post) is pretty much
card specific. And in most cases it's an echo command to a /proc
location or something similar, so those tools won't be needed.
