What are the scenarios they've developed
that disk mirroring addresses (at least in their minds?)
Incompetence –
they are basically a small company that has grown huge and the processes and
management leave a lot to me desired. The disk mirroring is used everywhere all
servers, all drives – everything is mirrored. Screw performance. It’s
a New Application, So that will be a new server and some more mirrors then….
Oh and the other reason is they use ArcServe – with every box having
different levels of agent and they all……. I could go on and on and
on and on and on. Time I got back into banking I think.

strategy question
I am absolutely fascinated by this Mark. What are the scenarios
they've devloped that disk mirroring addresses (at least in their minds?)
I know I'm getting ready to delve into some of this one more time
[1] and I'm always interested in adding one more crazy idea to the wall.
[1] more or less for fun this time.

well, I'd say AD won't have too much of an issue with it at all -
however, they'd have to reset the Exchange Server's machine-pwd or
rejoin it to the domain since it will likely not be able to create a
secure channel.
Not sure how the Exchange server itself will react to this time-warp (it
would likely cough up a bit)... but it doesn't sound like a scenario
that would hurt your AD.
Certainly important not to use this approach (using a mirror-disk) for
AD DC themselves (could be a potential solution if you could really
guarantee that you'd pull the disks from all DCs in the forest at the
same time - highly unlikely and certainly not recommended). But I'd
certainly also question this approach from a long-term
cost-perspective...

Where I am working at the moment part of their DR strategy consists of
breaking a mirrored pair and keeping it in a fire safe in the event of
server failures, I have managed to get them to drop this idea for DC's
but they still insist on doing it for other servers. Application servers
I don't care about but I do care about the Exchange server , they are
only pulling the mirror on the OS and the Application and not on
logfiles etc, as these are on raid 5. What would the impact be on AD if
they plugged the OS and Application disks back in after 3 months or
after AD tomestoning? What is the impact on the other files on the other
disks. The org is E2K3 and W2K3 too. It smells of deep deep sh.... to me
but, I want quantification.
