Creating Replication Resource Groups

This section describes how a replication resource group was created on the primary cluster and on the secondary cluster.

How to Create a Replication Resource Group on the Primary Cluster
  1. Access nodeA as superuser.

  2. Register SUNW.HAStoragePlus as a resource type.

    nodeA# /usr/cluster/bin/scrgadm -a -t SUNW.HAStoragePlus
  3. Create a replication resource group for the disk device group.

    nodeA# /usr/cluster/bin/scrgadm -a -g devicegroup-stor-rg -h nodeA,nodeB

    The name of the disk device group.


    The name of the replication resource group.

    -h nodeA, nodeB

    Specifies the cluster nodes that can master the replication resource group.

  4. Add a SUNW.HAStoragePlus resource to the replication resource group.

    nodeA# /usr/cluster/bin/scrgadm -a -j devicegroup-stor \
    -g devicegroup-stor-rg -t SUNW.HAStoragePlus \
    -x GlobalDevicePaths=devicegroup \
    -x AffinityOn=True

    The HAStoragePlus resource for the replication resource group.

    -x GlobalDevicePaths=

    Specifies the extension property that Sun StorEdge Availability Suite software relies on.

    -x AffinityOn=True

    Specifies that the SUNW.HAStoragePlus resource must perform an affinity switchover for the global devices and cluster file systems defined by -x GlobalDevicePaths=. Therefore, when the replication resource group fails over or is switched over, the associated device group is switched over.

    For more information about these extension properties, see the SUNW.HAStoragePlus(5) man page.

  5. Add a logical hostname resource to the replication resource group.

    nodeA# /usr/cluster/bin/scrgadm -a -L \
    -j lhost-reprg-prim -g devicegroup-stor-rg -l lhost-reprg-prim

    Where lhost-reprg-prim is the logical hostname for the replication resource group on the primary cluster.

  6. Enable the resources, manage the resource group, and bring the resource group online.

    nodeA# /usr/cluster/bin/scswitch -Z -g devicegroup-stor-rg
    nodeA# /usr/cluster/bin/scswitch -z -g devicegroup-stor-rg -h nodeA
  7. Verify that the resource group is online.

    nodeA# /usr/cluster/bin/scstat -g

    Examine the resource group state field to confirm that the replication resource group is online for nodeA and nodeB.

How to Create a Replication Resource Group on the Secondary Cluster

    Repeat the procedure in How to Create a Replication Resource Group on the Primary Cluster, with these exceptions:

    • Replace nodeA with nodeC.

    • Do not use nodeB.

    • Replace references to lhost-reprg-prim with lhost-reprg-sec.
