Why I don’t like GRUB – RHEL4 on system with local and external storage

Byetzion

Installed RHEL4 on a system with both internal storage (HP SmartAray 5i – cciss) and external disks through Qlogic FCS HBA.

During install, the local disks were detected as /dev/cciss/c0d0 while the external disks were detected as /dev/sda and /dev/sdb

After installation was done, Grub started with incorrect mapping. For no apparent reason, Grub searched for its stage2 and date in /dev/sda1 and not in /dev/cciss/c0d0p1.

The quickest way for me to solve it was to replace grub with Lilo (available on the fourth RHEL CD), correct /etc/lilo.conf.anaconda, copy this file to /etc/lilo.conf and run Lilo (with "-v" flag, for safety). It worked like a charm.
