[indiana-discuss] grub don't boot OpenSolaris 2008.05 after one reboot

[Vikram Hegde]

Hi,

Try the following commands at the GRUB prompt

find   /rpool/boot/grub/menu.lst
find /boot/grub/menu.lst

What do these show ?

Vikram

So I've not seen this, but maybe the boot order changed for some 
reason.  I don't see why the mbr would had been clobbered, even if the 
Solaris ramdisk was corrupted since the grub files are not dependent on 
the state of the ramdisk, which is the only real potentially breakable 
part of Solaris initialization.  It's possible the grub.conf got messed 
up though, which would result in the grub prompt being the only thing 
showing up.  You can boot the Windows and OpenSolaris systems through 
grub console.  You'd boot Windows something like this:

rootnoverify (hd0,0)
chainloader +1
boot

OpenSolaris is a little more trickey because it uses boot environments 
so you'd need to do something like this:

findroot (pool_rpool,1,a)
bootfs /rpool/RPOOL/opensolaris-5
kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS
module$ /platform/i86pc/$ISADIR/boot_archive
boot

* Type 'help' and there's a command to show devices, forgot what
* Tab complete works for some functions but not others, you could for 
example try bootfs /rpool/ROOT/[tab]
