It’s
the weekend, and so an excellent time to play on my lab and test something. The
awesome thing about NetApp’s software is how much power and flexibility it
gives you. I had every confidence the below was going to work, but nice to get
a chance to try it out. The Clustershell commands in Part 2 were run against
cDOT 8.2.3.
Scenario
1)
The Starting Point
We start with two sites - Site A and
Site B - and two cDOT clusters per site, with replication as below.

The Starting Point
2)
Setting up Baselines to a New Cluster in a New Site
We have a new site we want to move to. A
new cluster is stood up in Site C, and we set up baseline SnapMirrors from the
primary cluster (CLUA1 below) to our new cluster (CLUC1).

3)
Cutting Over the Production Cluster
On a scheduled day, we break SnapMirrors
and cutover data access to the new site, and manipulate the replications as
below.

4)
Lift and Shift of the SnapVault
Finally, we have to bring the SnapVault
cluster to our new site, but to complicate matters the SnapVault has to be
renamed with the new site (Site C) naming convention.
