Post Failover (Policy)

Introduction

This guide will go through the different checks that should be executed once Failover is finished.

Post Failover Steps Unique to Policy Failover

Networking Changes

Make the necessary networking changes required to redirect your clients to the Target Cluster. This may involve:

• PowerScale OneFS SmartConnect Zone updates
• Zone Alias Updates
• DNS Updates

Update SPNs

It may be necessary to update SPNs upon completion of Failover, if you add or delete any SmartConnect Zone or Zone Alias.

Manually Refresh SMB Connection

Please consult the guide on How to Manually Switch SMB Connection to Target Cluster After Failover at the link provided.

Refresh NFS Connection

After Failover is completed and DNS is updated, make sure to refresh NFS Connection.

Checklist

• File System Updates:
  • On the Source Cluster, the directories and subdirectories corresponding to the SyncIQ Policies that were failed over should be read-only.
  • On the Target Cluster, the corresponding directories and subdirectories should be writeable.
• Quota Updates:
  • After the update, there should be no quotas on the Source Clusters, and they should all be in the Target Cluster.
