Andrea: the answer is to use ufsdump/ufsrestore. We're in the same position
as you, and we ended up
with the locally-developed low-tech solution of using 8mm tapes with a tar
archive followed by the O/S ufsdumps. What we
then do in a DR is:
1: Boot the destination system with an OS CD. This doesn't even have to
be the same OS level as
the one we're restoring, we just need a running system.
2: Restore the tar archive and unpack it. This gives us a whole load of
documentation plus a script. We then run this
script which formats out the OS filesystems we need, (/, /usr, /var, etc).
3: The script then restores the data from the tape, (only the OS areas,
not application/data areas), and finally does
an installboot using the boot block, (and installboot), just restored from
tape.
4: Reboot with the newly restored OS, and TSM-restore everything else.
One of the things we're looking at is making boot images that could be
saved into TSM, and then reloaded via 'boot net -s', or
failing that a customised boot CD.
As other people have said you might want to seriously look at the Kernel
Group's 'Bare Metal Restore' product. However, if you check this
list's archive's you'll see that there are doubts over it's long term
future, given that Veritas now own it.
Oh, the other thing would be to use Sun's Jumpstart system along with
customised boot media. We're also looking at this, (as a low priority
item),
since it's standard and free, (I've got printed Jumpstart docs that came
with the installation media, but they're also available on docs.sun.com).
