5.6 HP StorageWorks X9000 File Serving Software User Guide (TA768-96035, June 2011)

Note the following:
• Several replication tasks can run in parallel.
• Each replication is either a continuous or a run-once task.
• The target subdirectories must not overlap. For example, if source cluster 1 is replicating to
<fs_root>dir1, source cluster 2 can replicate to <fs_root>dir2, but it cannot replicate
to <fs_root>dir1/dir2.
Configuring the target for remote replication
You can configure remote replication on the management console GUI or from the CLI. Use the
following steps to configure a target (a file system or directory) for remote replication. In this
procedure, target file system refers to either a file system or a directory.
NOTE: The steps are not required when configuring intracluster replication.
• Register source and destination clusters. A cluster must be registered before other remote
replication commands can use it as a target.
• Export the target file system. This step identifies the target file system for replication and
associates it with the source cluster. Before replication can take place, you must create a
mapping between the source cluster and the target file system that receives the replicated
data. This mapping ensures that only the specified source cluster can write to the target file
system.
• Identify the preferred hosts for replication storage and a preferred NIC for replication traffic
(optional). Select the hosts and network NIC, or use the default preferences. The default
preferences are as follows:
◦ Use all hosts that have the file system mounted.
◦ Use the cluster NIC on each host.
GUI procedure
This procedure must be run from the target cluster, and is not required for intracluster replication.
Select the file system on the GUI, and then select Remote Replication Exports from the lower
Navigator. On the Remote Replication Exports tab, click Export. The Create Remote Replication
Export dialog box allows you to specify the target file system for the replication.
For Export To (Cluster), select the source cluster of the file system to be replicated. If the source
cluster is not in the list, you will need to register the cluster. Click New to open the Add Remote
Cluster dialog box, and then specify the source cluster name and the IP address of the management
console for that cluster.
