Well I think that it is to be assumed that the hardware is identical or at
least similar. Going from IDE to SCSI is not similar. You could always just
install NT and ADSM at your hot site and not restore the entire server, just
the database log, volhist, devconfig, etc if you were testing recovering
clients. Checkout the Administrators Guide, Chapter 21 Using the Disaster
Recovery Manager, the section titled A DRM User Scenario details this well.
