Description Warren Togami 2005-05-27 23:31:45 UTC
+++ 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.

Procedure to workaround this problem and install grub in Rescue Mode is detailed
at this page.
