Can someone help recover my Solaris 10 install?
I've just installed OpenSolaris, and can't
get to my (pre-existing) Solaris 10 partitions.

Before installing OpenSolaris, I had the following solaris
partitions:

/dev/dsk/c5t0d0p1
/dev/dsk/c5t0d0s0
/dev/dsk/c5t0d0s5
/dev/dsk/c5t0d0s6

Most of the disc was devoted to the last of these,
mounted on /export.  This was hitherto unused, so
I assumed I could install OpenSolaris there.
I burned the 200805 ISO to a CD, and booted from it.

The OpenSolaris installer found four partitions,
though (slightly alarmingly) it didn't label them.
I selected the big one to install onto: the 200Gb
size difference made it clear which was the /export
partition.

The install went fine, but to my surprise it didn't
at any stage prompt me to configure the bootloader.
And when I reboot, the old Solaris 10 is not there
in the boot menu!  Neither can I mount the
Solaris 10 partitions to copy the relevant parts
from the old grub configuration:

nick at opensolaris:~# mount  /dev/dsk/c5t0d0s0 /mnt/solaris0
mount: /dev/dsk/c5t0d0s0 is not this fstype
nick at opensolaris:~# mount  /dev/dsk/c5t0d0s5 /mnt/solaris0
mount: I/O error
mount: Cannot mount /dev/dsk/c5t0d0s5
nick at opensolaris:~# mount -F zfs /dev/dsk/c5t0d0s0 /mnt/solaris0
cannot open '/dev/dsk/c5t0d0s0': invalid dataset name
nick at opensolaris:~# mount -F zfs /dev/dsk/c5t0d0s5 /mnt/solaris0
cannot open '/dev/dsk/c5t0d0s5': invalid dataset name


Can someone help with retrieving my Solaris 10?
