How to Configure a Remote Mirror Network Data Replication Volume Set between Two Oracle Solaris Clusters
Availability Suite (AS) Introduction
Sun Storage Availability Suite (AS) incorporates two distinct modules :
StoreEdge Network Data Replication (SNDR) also known as Remote Mirror (RM) or Remote Data Copy (RDC)
Instant Image (II) also known as Point-in-Time Copy (PiTC)
StoreEdge Network Data Replication (SNDR) is used to replicate disks, disk slices and logical volumes across a network to a remote server.
Instant Image (II) is used to take local shadow copies (instant images/snapshots) of disks, disk slices and logical volumes.
A logical volume can be under the control of either Solaris Volume Manager (SVM) or Symantec's Veritas Volume Manager.
Outline of this StorEdge Network Data Replication (SNDR) Example: Copy an active filesystem from one cluster to another.
Taking an active mounted filesystem that resides on Master_Cluster
Master Volume MV Mount Point: /<MHost>/MASTER_VOLUME SVM Volume: /dev/md/proddg/dsk/d1
and replicate the above filesystem to Remote_Cluster using host based data replication (SNDR)
Remote Mirror RM Mount Point: /<RHost>/REMOTE_MIRROR SVM Volume: /dev/md/proddgr/dsk/d1
Description of the underlying cluster configuration in this example.
Built upon Solaris 10, Oracle Solaris Cluster 3.3 with latest patches
Two Oracle Solaris Clusters each comprised of two nodes.
Master_Cluster First Node <MHost-1> Second Node <MHost-2>
Remote_Cluster First Node <RHost-1> Second Node <RHost-2>
Replicating from Master_Cluster to Remote_Cluster via a private network using Availability Suite Software Version 4.0 with latest patches
Master_Cluster Logical Host for replication: lh-<MHost>-sndr-pri
Remote_Cluster Logical Host for replication: lh-<RHost>-sndr-sec
Solaris Volume Manager (SVM) volumes and filesystems built upon Shared Storage.
The Master Volume (MV) and its associated filesystem on the primary cluster is configured as a failover cluster resource group.
The secondary cluster volume remote mirror (RM) is configured as a failover resource; however, manual intervention is required to mount the RM filesystem on Remote_Cluster.
