Ensure that the DNS server on Cluster A is the same as the DNS server or in the same DNS farm as the DNS server
of Cluster B. Existing client connections might break and might need to be re-established. You must unmount and
re-mount the NFS Exports on the client.
b. (Single NAS volume failovers) Manually update the DNS entry for the NAS volume that was failed over. This redirects
clients that are accessing this volume from Cluster B to Cluster A, while other clients keep accessing other volumes using
the same DNS name. Client systems might need to refresh their DNS cache.
c. (Single NAS volume failovers) To force SMB and NFS clients to Cluster A, you must delete the SMB shares and NFS
exports on Cluster B. This forces the SMB and NFS clients to reconnect, at such time they are connected to Cluster A.
After restoring the source volumes configuration on Cluster A, all of the SMB shares and NFS exports will be present on
the target volume (on Cluster A), so no SMB share/NFS export configuration information is lost.
The failed over volume can now be accessed using the exact same DNS name and SMB share/NFS export name as it
was when hosted on Cluster B, except now it is hosted on Cluster A.
d. Join Cluster A to the AD server or LDAP/NIS.
e. From Cluster A, configure replication between the original source volumes (A1, A2,.. , An) and the original target volumes
(B1, B2,.. , Bn) to prepare for the next disaster recovery.
File Access Notification
File access notification occurs when both systemwide file access auditing configuration is enabled and file operation matches
any active (enabled) preconfigured file access notification policy for the volume. Auditing events are generated after
permissions check for the file operation and before the actual execution of the operation.
