iSCSI SAN LUN not detected during RHEL installation via PXE

Hi,

Here is the issue I experience.

I want to do a CentOS 6.5 or RHEL 6.5 in a Boot From SAN configuration.

The server is a BL460c Gen 8 with Emulex 554FLB (iSCSI HBA).

I boot the server via PXE on a kickstart/DHCP server.

I have already a kickstart server working like a charm for a usual installation on local RAID 1 array.

If I perform the installation on the local RAID1 array of the server, it works fine.

I have modified my PXE boot to add the following parameters to the initrd.img loading:

- mpath

- linux

However, when anaconda is running, it doesn�t find any device corresponding to the SAN LUN !

When I do ALT + F4, I have checked that be2iscsi driver is properly loaded. I can see in /var/log/messages that no /dev/sd* is seen by the system. Only the /dev/sda corresponding to the local RAID1 array is seen.

I have tried to unload/reload the be2iscsi kernel module without more success.

I have tried to perform an installation directly booting on the ISO image of the RHEL 6.5 DVD (with the default drivers. I did not use the dd option to load another driver) and during the installation process, the LUN is properly seen and I can select it. I can ever see the 4 paths to the LUN !

I don�t understand what the manual installation with DVD is doing that my automatic (anaconda) is not doing to detect the LUN�

Thank you in advance to who can help me to figure out what is going on ! ;)
