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.

SyncIQ Policy Updates​
