BMR makes things really easy - once you set up your BMR server and make
everything work, it will restore system images that you create from a system to
identical hardware until the cows come home.
There are quite a few steps getting a Solaris server restored exactly like it
was before the rebuild. You are correct in assuming that a rebuild/restore of
a bootable system in a subordinate file system (as explained in the
Troubleshooting Guide) is not sufficient to restore the system. I have a
specific case documented (Solaris 8 on a Sun 6800) and will be happy to post it
if you want when I return home this weekend.

just a general question, but how are most of you folks handling disaster
recovery for Sun.
We're currently evaluating Veritas BMR, but right now our process is as follows.
All of our machines have, at the minimum, mirrored OS disks.
Our recovery involves jumpstarting the machine with a single disk,
c0t0d0...configuring netbackup, then creating slices on the second disk, c0t2d2
and mounting those from the OS running on the first......so c0t0d0s1 is mounted
on /mnt/a and c0t0d0s7 is mounted on /mnt/b.......the restore is then
performed, dumping the data onto /mnt/a and mnt/b.
once completed, we edit the config info on the disk, /mnt/a/etc/system,
/mnt/a/etc/fstab, etc.....to remove any reference to the SDS meta disks.
The machine is then rebooted on the c0t0d1, and the metadevices are created,
with one way mirrors, then the mirror is resynced back to c0t0d0.
pretty tedious, but i've been told that building the OS, with mirrors, then
restoring in place and overwriting existing files will not get the system back
to it's original state.
any comments???
