     Excuse the ignorance, but if I want to just want to put in a new drive
and restore the partitions and information and turn it into the boot drive,
how or why would I use jumpstart (I don't want to restore the whole OS)?
My understanding of the process is that you need to do a ufsdump first
against all the partitions on the drive.  Next, you use the 2.x cd in
single user mode (boot cdrom -sw) to get a prompt.  Then, you need to
partition the new drive and do the ufsrestore on it for each of the
partitions.  Then, you need to do an installboot against the new c0t0do
drive to turn it into a boot drive.  The question was how to use ADSM to
replace the ufsdump/restore process and how to get networked enough to gain
access to ADSM.  It is not clear to me how a system that had the drive with
/usr and / on it removed can be brought up and reconnected to the network
after booting from the cd rom.  I understand from your note that if you
could get to this state, you could start the ADSM daemon and gain access to
the ADSM server to do a restore.  In reference to your note, does the
backup restore the softlinks and hardlinks?  Did the mount point problems
occur because the mounts were not mounted during the restore?

Sincerely,

David

I've not done it with 2.4 however we do use Solaris jumpstart to rebuild
2.5.1 and 2.6 machines from ADSM backups. We hit one problem with ADSM
not backing up or restoring directories which are mount points. Apart
from that it worked well - much easier than AIX mksysb & NIM (not
intended as inflamatory).

How? OK the ADSM client code is loaded into the mini-root that Solaris
runs when the box is network booted. This client code can then contact
the ADSM server and restore the directories / /opt /usr and so on.

If you have many Solaris boxes and administrators the chances are
they've already built a jumpstart environment.
