nodeA# lockfs -a -f
nodeA# clresourcegroup status nodeC# clresourcegroup status
Examine the state field of the resource group.
This step enables replication from the primary cluster to the secondary cluster. This step enables replication from the master volume (d200) on the primary cluster to the master volume (d200) on the secondary cluster. In addition, this step enables replication to the remote mirror bitmap on d203.
If the primary cluster and secondary cluster are unsynchronized, run this command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -n -e lhost-reprg-prim \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d203 lhost-reprg-sec \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d203 ip sync
If the primary cluster and secondary cluster are synchronized, run this command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -n -E lhost-reprg-prim \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d203 lhost-reprg-sec \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d203 ip sync
Run this command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -n -a on lhost-reprg-prim \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d203 lhost-reprg-sec \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d203 ip sync
This step enables autosynchronization. When the active state of autosynchronization is set to on, the volume sets are resynchronized if the system reboots or a failure occurs.
Use the following command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -P
The output should resemble the following:
/dev/md/nfsset/rdsk/d200 -> lhost-reprg-sec:/dev/md/nfsset/rdsk/d200 autosync: off, max q writes:4194304, max q fbas:16384, mode:sync,ctag: devgrp, state: logging
In logging mode, the state is logging, and the active state of autosynchronization is off. When the data volume on the disk is written to, the bitmap file on the same disk is updated.
Use the following command for StorageTek Availability Suite software:
nodeA# /usr/sbin/iiadm -e ind \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d201 \ /dev/md/nfsset/rdsk/d202 nodeA# /usr/sbin/iiadm -w \ /dev/md/nfsset/rdsk/d201
This step enables the master volume on the primary cluster to be copied to the shadow volume on the same cluster. The master volume, shadow volume, and point-in-time bitmap volume must be in the same device group. In this example, the master volume is d200, the shadow volume is d201, and the point-in-time bitmap volume is d203.
Use the following command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -I a \ /dev/md/nfsset/rdsk/d200 \ /dev/md/nfsset/rdsk/d201 \ /dev/md/nfsset/rdsk/d202
This step associates the point-in-time snapshot with the remote mirror volume set. StorageTek Availability Suite software ensures that a point-in-time snapshot is taken before remote mirror replication can occur.
