The compelling reason to do what we did this past Sunday was to establish/confirm procedures for a "Plan B" and possible "Plan C" at DR. The problem with relying on the DR CFs is that the CFRM CF entries are specific to the model and serial involved ... and are therefore too closely tied to the whims of the DR vendor. If the DR vendor du jour upgrades or replaces the CF system and give us appropriate notice then "Plan A" will work without deleting or rebuilding anything (as you say). Trouble is, that vendor planning communication hasn't been all that reliable or timely in the past. That meant that having a Plan B and a Plan C seemed like a really good idea. I don't hate the idea of defining a fresh CFRM at the DR site; I dispute the widely held belief that there is no other option. -- Tom Schmidt
