I've been trying to build a bootable Kickstart DVD for RHEL 4 (AS4u3). I've got the booting part working no problem, all the packages are on the disc. We can even use the disc for a manual/interactive install. The problem I'm having with the process is getting Kickstart to partition the HDDs. I've got this whole process working like a champ on x86 hardware, but this /boot/efi has become a thorn in my side. The specifics are as follows: HP RX4640 4 Internal HDD, mapped into 2 RAID1 discs. The controller is recognized as CCISS The error I get is something like "can't find device cciss/c0d0 to use for /boot/efi" (sorry I don't have it word for word). At that point the only option is "OK" and reboot the machine. As I said above, if I use the same DVD and do a manual/interactive install everything works. Even if I let the installer build the partitions automatically it finds the cciss/c0d0 and labels it correctly /boot/efi. To add further confusion after the manual/interactive install is complete and I compare the "part" section of my ks.cfg with the one anaconda builds (/root/anaconda-ks.cfg) they are exactly the same.... Below is the section of my ks.cfg in question: part /boot/efi --fstype vfat --noformat --onpart cciss/c0d0p1 I've tried several permutations of --onpart, --ondisk, on that line. Also clearpart --all, --linux, --initlabel just before that line. Does anyone have any magic bullets, or examples of known working itanium ks.cfg's? Any help would be much appreciated.
