I can think of two things to check:
First, is there a 'bootfs' line in your grub entry? I didn't see it
in the original email; not sure if it was left out or it simply isn't
present. If it's not present, ensure the 'bootfs' property is set on
your pool.
Secondly, ensure that there's a z

If you can use NFS, can't you put things on ZFS and then export?
> bootfs rootpool/rootfs
does "grep zfs /mnt/etc/vfstab" look like:
rootpool/rootfs- / zfs - no -
(bet it doesn't... edit like above and reboot)
or second guess (well, third :-) is your theory that
can be checked with:
zpool import rootpool
zpool import datap
the root pool mounts fine - if I do:
zpool import rootpool
zpool get bootfs rootpool
mkdir /mnt
mount -F zfs rootpool/rootfs it mounts fine
/etc/zfs/zpool.cache exists
a zpool get all rootpool gets us:
size 19.9 G
used 3.67G
available 16.2G
capacity 18%

> panic[cpu0]/thread=fbc257a0: cannot mount root path /[EMAIL

when booted from snv_77 type:
zpool import rootpool
zpool get bootfs rootpool
mkdir /mnt
mount -F zfs "the bootfs string" /mnt
my guess is it will fail... so then do
zfs list
and find one that will mount,
After doing that, this is what we see:
panic[cpu0]/thread=fbc257a0: cannot mount root path /[EMAIL
PROTECTED],0/
pci8086,[EMAIL PROTECTED]/pci8086,[EMAIL PROTECTED]/pci1028,[EMAIL

fbc46790 genunix: rootconf+112 ()
fbc467e0 genunix:vfs_mo
Edit the kernel$ line and add '-k' at the end. That should drop you
into the kernel debugger after the panic (typing '$q' will exit the
debugger, and resume whatever it was doing -- in this case likely
rebooting).

There are multiple file system usages involved in Oracle RAC:
1) Oracle Home - This is where the oracle software lives. This can be
on a file system shared among all nodes or a per-host file system.

They *should* be the same level of "advancement", but each has a
different set of promises and expectations it needs to live up to..
