Comment 9 for bug 695842

So far we can boot in these scenarios:

1. One controller and no MD/LVM; no intervention required
2. Two controllers with no MD/LVM; manual grub install required
3. Two controllers with MD (RAID0) but no LVM; manual grub install required

Attached:

- syslog (10.10_2controllers-yesMD-noLVM_syslog)
- boot sectors for c0d0 and c1d0 (c0d0_sector and c1d0_sector)

From the last install (scenario 3), based on the boot sectors, I confirmed that c0d0 had GRUB installed and c1d0 did not (but do not see any successful installation to c0d0 in the log). Yet I do see where you then installed GRUB manually to each volume. What was in c0d0 might be a remnant of a previous install. Note that the installer is trying to install GRUB to /dev/md0 (?).

Then the manual interventions:
