How to load module into ramdisk
 

I need help on attempting to load a Subsystem disk module into ramdisk. I have never done this before.. My issue is IBMsdd and LVM2, after seeing all my SAN disks, running a pvcreate,vgcreate and lvcreate all is good. But when I reboot my server is puts the SAN VG into inactive. I was told I have to load the IBMsdd modules into Ramdisk.. Can anyone help?? I need baby steps on this one.. I have Redhat ES4 U5..

Well I don't know much/almost anything on SAN storage and IBMsdd but I found this from google:

http://publib.boulder.ibm.com/infoce...dd_1j60r6.html

Or in PDF if you prefer (page 32):

ftp://ftp.software.ibm.com/systems/s...oteboot_v2.pdf

Also in case there's any other links that might be of interest here's the google search results:

Hope that helps :)

Thanks mickyg, my scenario is a bit different. I am not booting from SAN, what I have is Redhat ES4 on internal disk but with two LVM's I have created for OS fs's and nonOS fs's along with a /, and a /boot.
