Administrator Guide

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 conguration 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 conguration 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, congure replication between the original source volumes (A1, A2,.. , An) and the original target volumes (B1,
B2,.. , B
n) to prepare for the next disaster recovery.
File Access Notication
File access notication occurs when both systemwide le access auditing conguration is enabled and le operation matches any active
(enabled) precongured le access notication policy for the volume. Auditing events are generated after permissions check for the le
operation and before the actual execution of the operation.
