just a general question, but how are most of you folks handling disaster
recovery for Sun.
=20
We're currently evaluating Veritas BMR, but right now our process is as
follows.
=20
All of our machines have, at the minimum, mirrored OS disks.
=20
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.
=20
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.
=20
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.
=20
any comments???
=20
