Chapter 12: HACMP for AIX Disaster Recovery

2.From one node in the cluster:

a.Determine the save set ID that contains the following configuration directories:

–/etc/objres

–/usr/es/sbin/cluster/etc/objres

–/usr/es/sbin/cluster/etc/vg

Note: The configuration directories in the previous list are valid for the HACMP Extended Scalability (HACMP/ES) version of HACMP. The actual configuration directory path may vary depending on your version of HACMP.

If you do not know the save set ID, use the scanner command to determine its value, as follows:

scanner device_path > /tmp/savefile 2>&1

b.Use the scanner -Scommands to restore the cluster database, as follows:

scanner -S saveset_id device_path -x uasm -i Y -rv /etc/objres

scanner -S saveset_id device_path -x uasm -i Y -rv /usr/es/sbin/cluster/etc/objres

scanner -S saveset_id device_path -x uasm -i Y -rv /usr/es/sbin/cluster/etc/vg

3.From the restored node in the cluster, use the SMIT utility to synchronize

the cluster topology and databases.

Task 3: Start the Cluster

To start the cluster:

1.Use the SMIT utility to bring up all nodes within the cluster.

2.Run the networker.cluster script on each node in the cluster.

3.Start the NetWorker resource group using the SMIT utility.

Task 4: Restore the Data

To restore the data from the primary node:

1.If you do not know the save set ID of the most recent bootstrap, use the scanner -Bcommand to find it, as follows:

scanner -B device_path
