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 -S commands 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 -B command to find it, as follows:
scanner -B device_path
