I have two questions:
1) Do you know if a SUSE installation does something special when GRUB is used for mirrored disks? Does it install stage1 in both MBRs or only in one MBR? AFAIK, it only installs it to the first disk. Check /boot/grub/menu.lst and /etc/grub.conf.
2) Independently of my first question, are there recommendations how to handle the situation? Shall I do the GRUB-setup for hd1, like I did for hd0? That is what I have always done. I don't have a separate /boot anymore since booting a root raid1 works. And since the BIOS is designed to boot from one drive, it works fine to boot from the MBR of the first drive most of the time. One gotcha I have run into is if the boot order is changed in BIOS, it changes the order Grub sees the disks. I don't yet know what would happen on my newer motherboard that instead of booting the first disk it boot the HD in a particular order, and if drive one failed, would grub still boot from the second. So, a kernel upgrade doesn't really affect the grub install if it was done correctly in the first place. Also, I have added a second menu item that boots from the second disk when the first dies. There is a RAID1 and Grub howto out there that also explains this. You can add a fallback entry to menu.lst to auto boot the second if the first fails. HTH.
