Unable to boot sles 11 sp3 on a HP G9 server


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) :

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

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?

Usually grub needs to know where the root filesystem is at the same time
the kernel location is specified. This is usually in the format of how
the device appears when the system is installed, but where you are
installing the system, I’m not sure what iPXE is doing. Perhaps try
giving the kernel line something like the following:


Good luck.
