Administrator Guide

NOTE:
• The requirements for NAS container replication are not validated when you create the replication partnership. The
system will not allow you to congure replication for a container if the source and destination clusters do not meet
the conguration requirements.
• Restoring volume conguration on the destination cluster is not supported between major revisions (such as version
3 > version 4).
Before conguring your network for replication, see the Installation and Setup Guide to complete the following tasks:
• Allocate and congure the NAS cluster
• Congure and assign an IP address for all network ports
• Verify that the correct ports are connected and remain operational at all times on the NAS systems
About Replicating to a Partner
Replicating to a partner uses the partnership congured in the failover process to recover data to the source, or primary, container.
After the failover, data on the recovery container is written to the primary container. If you are replicating to a new container, all of
the data on the recovery container is written to the newly congured primary container.
If the original primary container is no longer available and the recovery container is congured to replicate to another container, the
replication process takes longer than it would if you were replicating back to the original primary container. Replicating to the original
source container writes only data written to the recovery container after the failover back to the source container. However,
replicating to a new source container writes all of the data to the new source container, and might aect client access performance.
You can perform these operations manually as part of the replication process or you can perform them as part of the single-step
failback process. Time and bandwidth, as well as the amount of data being written to the source container, aect how much time
the single-step failback process takes.
Manually Replicate a NAS Container
Before you can replicate a container, the container must be congured for replication and must have a replication partner congured.
The amount of time that the replication takes to complete depends on the size of the NAS container and the network connection.
To replicate a NAS container:
1. On the source cluster, click NAS, expand Local Containers, and select the NAS container that you are replicating.
2. Click Replicate.
3. Click Yes.
4. (Optional) Display the Alarms and Operations toolbar and click the Failback Operations tab.
Pause or Resume Replication of a NAS Container
1. In the navigation menu, click NAS, then select the NAS cluster on which the container resides.
2. Expand Local Containers and select the container.
3. In the Activities panel, either:
• Click Pause replication to pause replication.
• Click Resume replication to resume replication.
4. Click OK.
Activate the Destination Cluster
After you promote the destination containers, congure the destination cluster to serve client requests:
• Apply the same cluster settings to the destination cluster that were congured on the source cluster.
• Enable the destination cluster to perform the same function as the failed source cluster.
