EVA3000, QLA2340 & linux not seeing new LUNs without a reboot
Here are the facts:
EVA3000
SUSE linux 9.1
QLA2340 (two for multi path fail-over)
Currently the server is sitting with 6 LUNs attached and in use, one LUN presented but not completely seen by SUSE. (See dmesg) and one LUN has been resized, which is in the same state as the newly presented disk. (Output from fdsik & dmesg)

Re: EVA3000, QLA2340 & linux not seeing new LUNs without a reboot
There are numerous ways to accomplish this, but the one that works for me is...
sfdisk -R /dev/sd?
where /dev/sd? is your resized LUN (ie. sda, etc.)

We can consider this closed. I resolved the issue myself.

Re: EVA3000, QLA2340 & linux not seeing new LUNs without a reboot
Mind sharing how you resolved the issue? Sfdisk or HPFibreChannel Utilities or something else did the trick?

Re: EVA3000, QLA2340 & linux not seeing new LUNs without a reboot
Firmware version 3.02.30 IPX, Driver version 8.00.00b14-fo
Notice the "b14" and the firmware version.
HP had me uninstall SUSE's drivers and manually install theirs as there is a problem with the 64bit drivers logic in the install.sh script. Now everything works fine under the following setting.
Firmware version 3.03.01 IPX, Driver version 8.00.00-fo
