Removing a cluster monitor

A cluster monitor provides another source of information to allow cluster resource services to determine when a cluster node has failed.


Be cautious when removing a cluster monitor. If you remove a node from a cluster monitor, and that node is the current primary point of access for any CRG, that node could partition when in fact, the node really failed. This means the user must now do manual steps to become highly available again.

PowerHA GUI only supports the Common Informational Model (CIM) server for the cluster monitor. The Remove Cluster Monitor command must be used if you want to use the representational state transfer (REST) server.

To remove a cluster monitor using the PowerHA® graphical interface, follow these steps:

  1. On the Cluster Nodes page, select Properties ... from the context menu of the node to which you want to remove a cluster monitor.
  2. In the Cluster Monitors section of the Properties page, select Remove ...from the context menu of the cluster monitors you want to remove.
  3. Click Yes on the confirmation panel.
