Netapp Failover from one cluster to another cluster

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.

hi

 

Yes, after you break SnapMirror, remount it on the client using the IP and Junction path of the DC B cluster
