Netapp Failover from one cluster to another cluster

[MohitS]

We are migrating from DC A to DC B, currently we have configured SVM DR b/w 2 FAS systems in DC A and 1 AFF system in DC B.

I want to know when I break the snapmirror and bring the netapp systems in site A down and the one in site B becomes RW, what all changes are needed to be made from the windows and unix servers so that they point to the cluster in site B.

I assume this is NAS? Assuming you are using -identity-preserve true

For NAS:

• NFS clients should reconnect once the SVM has been activated by the snapMirror break command
• CIFS/SMB clients will have to reauthenticate (this is a limitation of SMB). This should happen by refreshing your SMB connection.

Hi Mohit, As a customer you have access to a free lab resource to try this out here: https://labondemand.netapp.com/search/snpmirrep 

If you go through the lab guide and get to the section on SVM DR you can see firsthand what Tony is describing.
