Using intercluster replication
Intercluster configurations can be continuous or run-once. The following steps are required when
configuring intercluster replication:
• Register source and destination clusters.
• Create a target export.
• Identify server assignments to use for remote replication.
This section explains how to perform continuous remote replication in different clusters and different
file systems using the StoreAll OS CLI.
• Create two mounted file systems, fs1 and fs2, each containing two segments, using the LUNs
that are exported from the HP 3PAR StoreServ Storage both on source and target clusters.
• Register the source cluster with the target cluster and vice versa using the following command:
# ibrix_cluster -r -C CLUSTERNAME -H REMOTE_FM_HOST
• Export the file system from Target cluster to source cluster using the following command
# ibrix_crr_export –f FS NAME [-p DIRECTORY] –C SOURCE_CLUSTER [–P]
• Start I/O on the source cluster’s file system fs1 until it is 60% full. Check fs1 for usage
percentage using the following command:
# ibrix_fs –i
• Use the following command to start a continuous or run-once intercluster replication task for
the specified file system from the source cluster:
# ibrix_crr -s -f SRC_FS NAME [ -o] [-S SRCDI R] –C TGT _CLUSTERNAME -F TGT_FS
NAME [-X TGT EXPORT] [ -P TGTDI R] [-R]
For example, to start a continuous remote replication from source file system fs1 to target file
system fs2 on the target cluster eos172s3_4, use the following command:
# ibrix_crr -s -f fs1 -o -C eos172s3_4 -F fs2
• After replication from fs1 to fs2 completes successfully, check for fs2 usage percentage, as
shown in the following example:
# ibrix_fs -f fs2 –i
