Before You Begin
Complete the procedure How to Perform a Point-in-Time Snapshot.
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: on, max q writes:4194304, max q fbas:16384, mode:sync,ctag: devgrp, state: replicating
In replicating mode, the state is replicating, and the active state of autosynchronization is on. When the primary volume is written to, the secondary volume is updated by StorageTek Availability Suite software.
Use the following command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -n -u 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
client-machine# umount /dir
nodeA# clresource disable -g nfs-rg + nodeA# clresourcegroup offline nfs-rg
Run the following command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -n -l 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
When the data volume on the disk is written to, the bitmap file on the same disk is updated. No replication occurs.
nodeC# mount | grep /global/etc
nodeC# fsck -y /dev/md/nfsset/rdsk/d200
nodeC# clresourcegroup online -emM nodeC nfs-rg
You see a prompt that resembles the following:
client-machine#
client-machine# mount -o rw lhost-nfsrg-sec:/global/mountpoint /dir
client-machine# ls /dir
nodeC# clresource disable -g nfs-rg + nodeC# clresourcegroup offline nfs-rg
nodeC# umount /global/mountpoint
nodeA# clresourcegroup online -emM nodeA nfs-rg
Run the following command for StorageTek Availability Suite software:
nodeA# /usr/sbin/sndradm -n -u 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
When the primary volume is written to, the secondary volume is updated by StorageTek Availability Suite software.
