CoordPoint agent

Use the Coordination Point (CoordPoint) agent to monitor the registrations on the different coordination points on each node. You use this agent to provide server-based I/O fencing. The CoordPoint agent is a monitor-only agent that runs on each node within the client cluster. When you have configured a CP server as a coordination point, the CoordPoint agent performs the following tasks:

• Confirms that the CP server coordination point can communicate with the client cluster.
• Validates the node registrations in the CP server database using the cpsadm command.

In case the coordination point is a SCSI-3 based disk, the CoordPoint agent uses the vxfenadm command to confirm that the registered keys on the disk are intact. The Monitor agent function contains the monitoring functionality for SCSI-3 disks and CP servers.

If the agent detects an anomaly, the agent reports it to you so you can repair the coordination point. You may have to perform an online coordinator point replacement procedure if the problem is isolated to the keys registered.

Note   The CoordPoint agent that runs on a given client cluster node monitors the keys for coordination points visible to that node alone.
