Adding Managed Nodes
This procedure walks you through adding managed nodes to a new management domain.
Managed node systems must be running a supported version of HP-UX or Linux. Adding
a managed node involves:
• setting the agent configuration password
• verifying the default WBEM and SNMP usernames and passwords
• verifying the default authorizations
• installing the DTF agent and WBEM software
• configuring the managed node
• adding the new node to the management domain
• adding the new node to the Managed Nodes node group
• testing the new node
To add a managed node, you can either:
• automatically add a group of managed nodes using the add_nodes script
• manually add managed nodes
The add_nodes script walks you through adding managed nodes. Using this script will
significantly reduce the time and complexity of adding managed nodes.
NOTE The SCM software must be installed on the central management server (CMS) prior to
adding a managed node, and the CMS must be available on the network. See “Installing
Servicecontrol Manager on HP-UX” on page 30 or “Installing Servicecontrol Manager on
Linux” on page 33 for details.
NOTE The CMS and managed nodes must be time-synchronized to prevent authentication
failures. The communication time limit is 20 minutes, and exceeding this limit causes
authentication failures.
NOTE This procedure assumes that SNMP is configured on each managed node. If you want to
use SNMP tools with SCM, SNMP should be configured prior to adding managed nodes.
By default, SNMP is configured on HP-UX systems.
To automatically add managed nodes:
Step 1. Log on to the CMS as root.
Step 2. Run the add_nodes script.
/opt/mx/lbin/add_nodes node1 node2 node3...
where node1 node2 node3... is the list of hostnames or IP addresses for the nodes you
want to add.
Step 3. Verify the new nodes by testing the configuration:
/opt/mx/bin/mxexec -t df -n node1 node2 node3...
where node1 node2 node3... is the list of hostnames or IP addresses for the nodes you
added.
