Not possible, sorry. The standard approach that SUN uses is to:

- install media for a base system, including ODS
- install Solaris via CD or network
- install and configure DiskSuit
   [don't know what you do for Solaris 9,
   but I expect you can skip this step]
- configure volumes per your saved system configuration
- restore from backup tapes or software

Veritas sells a product called "Bare Metal Restore" and there's a a
mksysb clone floating around but it doesn't work with ODS nor will it
produce a bootable tape.

Although ODS keeps the volume configurations on a filesystem that's
backed up, it still requires you to configure the volumes prior to
restore. I haven't tried restoring a system disk from tape and
rebooting. I expect that not to work.

Sorry, there's no easy fix here unless you want to roll your own
solution.
