Unable to boot sles 11 sp3 on a HP G9 server

Hello,

I'm trying to boot SLES 11 SP3 on a HP G9 DL380 server with RAID p380 in UEFI. I have this configuration in my bootloader (iPXE) :

Code:
kernel https://server/sles11-x86_64/disc1/boot/x86_64/loader/linux splash=silent install=https://xxx autoyast=https://xxx load_ramdisk=1 dud=0 textmode=0 edd=on initrd=initrd
initrd  https://server/sles11-x86_64/disc1/boot/x86_64/loader/initrd
boot

But I'm getting a kernel panic

Code:
 VFS: Cannot open root device "(null)" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Can you help me to solve the issue please?

A kISO boot image is required for SLES 11 to be installed on Gen9

 

HP ProLiant Gen9 Installation Kits for SUSE Linux Enterprise

https://drivers.suse.com/hp/HP-ProLiant-Gen9/

Download the image and boot from it, you will then be asked to insert disc1 if the normal media. 

For PXE boot you need a line similar to below

label SLES-11-SP3-x86_64-kISO (Gen9)
        kernel SLES-11-SP3-x86_64/kISO-Gen9/linux
        append vga=normal initrd=SLES-11-SP3-x86_64/kISO-Gen9/initrd install=http://x.x.x.x/mrepo/SLES-11-SP3-x86_64/disc1 addon=http://x.x.x.x/mrepo/kISO-Gen9_SLES-11-SP3-x86_64/disc1/

 

You need to use the kernel and initrd image included in the kISO image

Sorry I can't login on my other account..

You mean trying with that image https://drivers.suse.com/hp/HP-ProLiant-Gen9/sle-11-sp3-x86_64/2.0/install-readme.html ?

Just replacing the SLES kernel by the one from this page (without changing any other params) leads to the very same problem. But I need more testing.

Re: Unable to boot sles 11 sp3 on a HP G9 server

This drive kit image provided by SUSE is required to install SLES 11 SP3 on a Gen9 ProLiant.   I haven't experienced the error you are seeing when loading SLES on any ProLiant.

 

I'm not that familiar with iPXE syntax. The syntax I provided is from a working PXE system using pxelinux.0 from the Syslinux package.  I also uses ELILO for PXE booting UEFI and that looks like this:

image=/kISO-Gen9_2.0-9_SLES-11-SP3-x86_64/linux
    label=SLES-11-SP3-x86_64-kISO_2.0-9
    description = "SLES 11 SP3 kISO Gen9 v2.0-9"
    initrd=/kISO-Gen9_2.0-9_SLES-11-SP3-x86_64/initrd
    append="vga=normal install=http://x.x.x.x/mrepo/SLES-11-SP3-x86_64/disc1 addon=http://x.x.x.x/mrepo/kISO-Gen9_2.0-9_SLES-11-SP3-x86_64/disc1/"

Re: Unable to boot sles 11 sp3 on a HP G9 server

Ok I will do more tests with this kit and report my findings here.

On the information page about this kit there is

The driver kit contains updates to the SUSE Linux Enterprise kernel and Xen hypervisor as well as updated device drivers required for installation.

What does that mean ? Is the kernel updated in some way to support the disks?

Thank you for your help
