+++ This bug was initially created as a clone of Bug #158158 +++ RHEL4-U1-re0525.0 fails I2O grub install. This is the same problem as Bug #158158 from Fedora. ALT-F5 says this after installation is complete: grub> root(hd0,0) Filesystem type is ext2fs, partition type 0x83 grub> install /grub/stage1 d (hd0) /grub/stage2 p (hd0,0)/grub/grub.conf Error 22: No such partition Bug #158158 found that grub had incorrect i2o partition detection code, using cciss-like device names when /dev/i2o/* devices are really more like IDE device names. The replacement patch in that bug solves this issue. Impact: RHEL4 installs on I2O controllers (many Adaptec and other brand of SCSI RAID, still selling today), but grub fails to install because it cannot find the device from Anaconda. Mitigating Workaround: If we do not patch grub, users can boot into rescue mode, chroot into the /mnt/sysimage and "grub-install /dev/i2o/hda" in order to install grub. We should consider this for RHEL4 because the fix is well understood and does not affect non-I2O devices.
http://i2o.shadowconnect.com/rhel.php Procedure to workaround this problem and install grub in Rescue Mode is detailed at this page.
