 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 Cluster Boston

             Master Volume MV   Mount Point: /boston/MASTER_VOLUME      SVM Volume: /dev/md/proddg/dsk/d1

        and replicate the above filesystem to Cluster Newton using host based data replication (SNDR)

             Remote Mirror RM    Mount Point: /newton/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.

     Cluster Boston      First Node phys-boston-1   Second Node phys-boston-2  
     Cluster Newton     First Node phys-newton-1  Second Node phys-newton-2  

   Replicating from Cluster Boston to Cluster Newton via a private network using Availability Suite Software Version 4.0 with latest patches

            Cluster Boston Logical Host for replication:  lh-boston-sndr-pri

            Cluster Newton Logical Host for replication: lh-newton-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 Cluster Newton.

Solution
 Prerequisites
 Optional Items
 1.  Create the filesystems and underlying volumes on each cluster according to Appendix 1.
 2.  Create the cluster resources on each cluster and test failover according to Appendix 2.
 3.  Verify that cluster logical hosts used for data replication across the network are up.
 4.  Determine the cluster nodes mastering the resources on each cluster.
 5.  Create a remote mirror replication volume set.
 6.  Enable "autosync" to avoid the need for administrator's routine intervention (optional).
 7.  Start synchronisation of the remote mirror. Copies data from the first Cluster Boston to the second Cluster Newton.
