Hi,

I try to configure the bootloader for SUSE 10.1 on a Sunfire X4100 with the following disk configuration:

2 SAS drives combined as a mirror via the SAS controller on SCSI id 0 2 other SAS drives on SCSI ids 2 and 3

In my autoyast profile I have the following section:

<bootloader> <activate config:type="boolean">true</activate> <global config:type="list"> .... </global> <initrd_modules config:type="list"> <initrd_module> <module>mptsas</module> </initrd_module> <initrd_module> <module>scsi_mod</module> </initrd_module> .... </initrd_modules> <loader_device>/dev/sdc</loader_device> <loader_type>grub</loader_type> <location>mbr</location> <sections config:type="list"> <section config:type="list"> <section_entry> <key>title</key> <value>Linux</value> </section_entry> <section_entry> <key>kernel</key> <value>(hd2,4)/vmlinuz root=/dev/sdc7 vga=normal console=ttyS0,9600 console=tty0 noresume showopts</value> </section_entry> <section_entry> <key>initrd</key> <value>(hd2,4)/initrd</value> </section_entry> </section> <section config:type="list"> <section_entry> <key>title</key> <value>Failsafe</value> </section_entry> <section_entry> <key>kernel</key> <value>(hd2,4)/vmlinuz root=/dev/sdc7 vga=normal console=ttyS0,9600 console=tty0 noresume showopts ide=nodma apm=off acpi=off edd=off nosmp noapic maxcpus=0 3</value> </section_entry> <section_entry> <key>initrd</key> <value>(hd2,4)/initrd</value> </section_entry> </section> </sections> </bootloader>

I want to install everything on the mirror which for whatever reason always appears as the last drive, even if it is SCSI id 0. But this seems to be a driver or controller issue and I can live with that. In my case the mirror is /dev/sdc resp. for grub it's (hd2).

In the BIOS I explicitely set it to boot ONLY from the mirror and don't even look on the other drives.

Now what happens is that Yast installs everything fine on the mirror but after the reboot the system doesn't come up anymore. The reason is that Yast never puts grub into the MBR on the mirror but instead puts it into the MBR of the first non-mirrored drive (which doesn't even have a valid partition table). This is the y2log_bootloader:

GNU GRUB version 0.97 (640K lower / 3072K upper memory)

[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd2,4) Filesystem type is ext2fs, partition type 0x83 grub> install --stage2=/boot/grub/stage2 /grub/stage1 d (hd2,4) /grub/stage2 0x8000 (hd2,4)/grub/menu.lst grub> install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0) /grub/stage2 0x8000 (hd2,4)/grub/menu.lst grub> quit

Is that intentional behaviour and how can I get around it? Or is it just broken, in which case I can file a bug on bugzilla?
