Messing around with MACH11

I recently had the pleasure of playing around with MACH11 in a demo environment. In much the same way as onbar is trivial to set up once you have a storage manager going, once you've got all the background hoo-hah of building instances done, it's amazingly simple to build a MACH11 cluster!

You need to tell the primary that it's the primary for each kind of replication you're going to use (with onmode -d commands. In my case it was HDR, SDS and RSS -- going for broke.

• You need to set up some non-shared disk for SDS.
