RedHat Advanced Server & 12h autoraid

[Eric Kaiser]

Folks,
Hope someone can help with my issue. I have HP L3R and am installing RedHat AS 2.1 connected to a HP 12h. My issue is that after I formatted the array, created 6 luns at 20 Gb each and began the install of RH AS 2.1 the install only see's the first lun, (Lun 0 @ 20gb). My firmware on the array is HP62 which I believe is recent. Any help would be most appreciated!!

I also confirmed my six luns were created thru the console and they ARE all there. Thanks!

1) edit /etc/lilo.conf and append the following line to the end of the file:

append="max_scsi_luns=X"

where: X is the number of LUNs per SCSI device, between 1 and 128.

2) Enable "probe all LUNs" in the scsi subsystem configuration of the "make menuconfig" or "make xconfig"

3) Recompile the kernel.

Good luck!

At the installation prompt, you should be able to type 'max_scsi_luns=X' so that the Installation procedure can see them too.

on the machine SCSI BIOS for the controller enable multi LUN support

Your right, I did enable the scsi support in the BIOS and now I see it from a bios prespective, but AS 2.1 still doesnt see it. I tried adding that line of max luns but it didnt see it durning install. I just installed to my internals and will modify the grub.conf upon installation completion to get it to see it. If I am still missing something, let me know. I will keep you posted on the success of the grub.conf when it comes up. Thanks!
