How to Enable Replication on the Secondary Cluster

Before You Begin

Complete the procedure How to Enable Replication on the Primary Cluster.

  1. Access nodeC as superuser.
  2. Flush all transactions.
    nodeC# lockfs -a -f
  3. Enable remote mirror replication from the primary cluster to the secondary cluster.

    Use the following command for Sun StorageTek Availability Suite software:

    nodeC# /usr/sbin/sndradm -n -e lhost-reprg-prim \
    /dev/vx/rdsk/devgrp/vol01 \
    /dev/vx/rdsk/devgrp/vol04 lhost-reprg-sec \
    /dev/vx/rdsk/devgrp/vol01 \
    /dev/vx/rdsk/devgrp/vol04 ip sync

    The primary cluster detects the presence of the secondary cluster and starts synchronization. Refer to the system log file /var/adm for Sun StorageTek Availability Suite for information about the status of the clusters.

  4. Enable independent point-in-time snapshot.

    Use the following command for Sun StorageTek Availability Suite software:

    nodeC# /usr/sbin/iiadm -e ind \
    /dev/vx/rdsk/devgrp/vol01 \
    /dev/vx/rdsk/devgrp/vol02 \
    /dev/vx/rdsk/devgrp/vol03
    nodeC# /usr/sbin/iiadm -w \
    /dev/vx/rdsk/devgrp/vol02
  5. Attach the point-in-time snapshot to the remote mirror set.

    Use the following command for Sun StorageTek Availability Suite software:

    nodeC# /usr/sbin/sndradm -I a \
    /dev/vx/rdsk/devgrp/vol01 \
    /dev/vx/rdsk/devgrp/vol02 \
    /dev/vx/rdsk/devgrp/vol03
