SnapMirror failover
So I helped a customer a few months ago (before SRM) to script a complete site failover. It will bring the DR site online within about 30 minutes, the scripts are a bit clunky and need a massive re-design, so I thought I’d post the originals here.
This, I think, is a great example of how flexible the NetApp systems are in that you can quickly and easily setup SSH access from a management host and script your heart away! Soon as I get the hang of the API, I’m sure there’ll be plenty more info coming along too.
This script will bring all volumes online on the DR filer, what’s more, an volume that is labelled as “_vm” at the end (which is a nice naming convention to use for all VMware volumes anyway), will get re-mapped to a new igroup you choose and already have setup for the DR ESX servers.
I’ve modified this script slightly since writing it to remove filer names, so I don’t expect it to work out of the box, as with my other scripts, it’s just meant to as an example of how this can be achieved.
