Unanswered question This question has not been answered yet.
I have ran into an issue trying to install SLES 11 SP1 on a Power 7 9117-MMB model with a IBM PCI-X DDR 3Gb SAS RAID Adapter (572F). The initial install via the Tool Kit 5.1 goes well. The SLES OS is laid down and packages installed. When the OS reboots we get an error which we were able to determine was with the NVRAM - http://www.ibm.com/developerworks/wikis/display/LinuxP/Claim+failed+for+initrd+error+with+SUSE. we followed the instructions and wiped-nvram. The server booted, however we have to repeat this every time the server boots, some how the NVRAM keeps getting reset. I scraped this install and installed without the Tool Kit, the install completed successfully. It would then appear that there is an issue with the Tool Kit...? There could also be some compatibility issue with the IBM PCI-X DDR 3Gb SAS RAID Adapter (572F). I tried an initial install of SLES 11 SP2 which has NVRAM fixes, however the install CD would not boot with our Power 7 hardware. Any ideas? Anyone ran into this issue before?

Boot the server with the IBM Installation Toolkit DVD2. Used it to start an installation of SLES 11 SP13. The machine rebooted4. The OS installation was correctly done5. The machine rebooted again6. Boot problemsA. Is this correct?The boot problem was *exactly* the one described at http://www.ibm.com/developerworks/wikis/display/LinuxP/Claim+failed+for+initrd+error+with+SUSE? In other words:boot: linuxPlease wait, loading kernel...Elf64 kernel loaded...Loading ramdisk...Claim failed for initrd memoryramdisk load failed !ENTER called ok0 >B. Is this correct?After the boot problem, you did:1. Run "dev nvram" and "wipe-nvram" on the OpenFirmware prompt (the "0 >" above)2. Without reinstalling anything, was able to boot the SLES 11 SP1 installed with IBM Installation Toolkit3. The system booted perfectly and you could use it4. Eventually, you rebooted the server5. The original boot problem happened againC. Is this correct?Finally:1. You reinstalled SLES 11 SP1, now without toolkit2. There were no boot problems3. Whenever you reboot the server, no boot problems occurD. Is this correct?Thanks,Rodrigo

Hi Rodrigo, The answer is Yes for ABC and D.I think the Tool Kit incorrectly writes the yaboot in this case.I have been able to install with the Tool Kit on Power 6 with no issues at all. We are migrating to the Power 7 hardware and came to these issues.I have a different RAID card coming on Thursday and I'm going to try the install with and without the Tool Kit to see if the issues is with a specific card or not.
