Step 1 -- determine which servers are 'critical' and which are 'nice to
have'; find out what the expectations are for getting the 'critical' back on
line. For example, our requirement is to recover to within 12 hours of the
outage in less than 48 hours. Make sure your backup/archive/off-site
rotation strategy matches. Ours doesn't :-(

Step 2 -- work out what you need to rebuild from scratch. For the SP frame,
you'll need to rebuild the CWS (mksysb tape); then delete all nodes and
frames, and re-acquire frames and nodes (your hot-site will NOT match your
configuration, trust me!). Then re-customize and boot/install from your node
images on disk. Back when we had an SP frame, I kept the adsm node image on
the CWS disk and had a savevg of the volume group.

I don't know about Alpha or Solaris -- there are some nice writeups from IBM
on 'bare metal restore' for NT, and AIX recovers nicely with mksysb
(complicated, on the SP frame by the nature of the beast).

You might want to take a look at the archives here
http://msgs.adsm.org/cgi-bin/get/adsm-current.html for other suggestions.

FWIW -- we were an SP frame shop, with TSM on a wide node, and ran several
successful D/R tests. Now we have 6 RS/6000 systems, two MS-Exchange
servers, and a Rightfax system covered on our hot-site contract. We do not
use DRM or third party tools; just in-house scripts and well-written
procedures.
