why not vol move everything to one pair, then remove the other pair from the cluster.
make a new 2-node cluster, snap mirror everything, then ship.
then re-make the 4 node cluster once you safely arrive at the destination.

or, ship the temp 2-node pair first, *then* snapmirror everything to it (requires a decent WAN)
so the data is known safe at the destination before you move the origin cluster.

Guys,
We're getting ready to move our 4 node FAS8060 cluster to a new data
center.  As part of our due diligence, we're thinking that we would
snapmirror the most critical business volumes between the two pairs.

The idea would be that if the truck holding pair A+B doesn't make it
for some reason, we can still bring up the cluster with nodes C+D and
still have those snapmirrored volumes available to continue working.

So my questions are:

1. Can I boot a cluster with half the nodes missing?  I'm sure I
   can...

2. Has anyone else had to do this half assed method of shipping DR?

Cheers,
John
