1. Register the source and target clusters with each other using the ibrix_cluster -r

command if needed. To list the known remote clusters, run ibrix_cluster -l on the source

cluster.

2. Create the export on the target cluster. Identify the target export and associate it with the

source cluster using the ibrix_crr_export command.

3. Identify server assignments for the replication export using the ibrix_crr_nic command.

The default assignments are:

• Use all servers that have the file system mounted.

• Use the cluster NIC on each server.

Registering source and target clusters

Run the following command on both the target cluster and the source cluster to register the clusters

with each other. It is necessary to run the command only once per source or target.

ibrix_cluster -r -C CLUSTERNAME -H REMOTE_FM_HOST

CLUSTERNAME is the name of the Fusion Manager for a cluster.

For the -H option, enter the name or IP address of the host where the remote cluster's Fusion

Manager is running. For high availability, use the virtual IP address of the Fusion Manager.

To list clusters registered with the local cluster, use the following command:

ibrix_cluster -l

To unregister a remote replication cluster, use the following command:

ibrix_cluster –d –C CLUSTERNAME

Creating the target export

To create a mapping between the source cluster and the target export that receives the replicated

data, execute the following command on the target cluster:

ibrix_crr_export –f FSNAME [-p DIRECTORY] –C SOURCE_CLUSTER [–P]

FSNAME is the target file system to be exported. The –p option exports a directory located under

the root of the specified file system (the default is the root of the file system). The -C option specifies

the source cluster containing the file system to be replicated.

Include the -P option if you do not want this command to set the server assignments. You will then

need to identify the server assignments manually with ibrix_crr_nic, as described in the next

section.

To list the current remote replication exports, use the following command on the target cluster:

ibrix_crr_export -l

To unexport a file system for remote replication, use the following command:

ibrix_crr_export –U –f TARGET_FSNAME [-p DIRECTORY]

Identifying server assignments for remote replication

To identify the servers that will handle replication requests and, optionally, a NIC for replication

traffic, use the following command:

ibrix_crr_nic -a -f FSNAME [-p directory] —h HOSTLIST [-n IBRIX_NIC]
