Is it or isn''t it possible to boot off two mirrored ZFS disks and if
yes, can this be done in the upcoming solaris 10 10/08 too?

Yes. Yes.  For details, please consult the ZFS Administration Guide.

Dick,

Well, not at the same time. :-)

If you are running a recent SXCE release and you have a mirrored ZFS
root pool with two disks, for example, you can boot off either disk,
as described in the ZFS Admin Guide, pages 81-85, here:

http://opensolaris.org/os/community/zfs/docs/

If you create a mirrored root pool of two disks during an initial
install, then you can boot from either disk automatically.

If you add the second disk to the root pool to create a mirrored
root pool by using the zpool attach command, then you''ll need to
add the bootblock to the second disk as described in these pages,
to workaround a current bug.

Yes, booting from either disk in a mirrored root pool can be
accomplished in the upcoming Solaris 10 release as well.
