Putting an HA Resource Group into Maintenance Mode

Putting an HA resource group into maintenance mode disables HA resource group monitoring. When an HA resource group is in maintenance mode, stopping and starting the products in that HA resource group do not cause failover.

To put an HA resource group into maintenance mode, on the active cluster node, create the following file:

  • Windows: %NnmDataDir%\hacluster\<resource_group>\maintenance
  • Linux: $NnmDataDir/hacluster/<resource_group>/maintenance

Note The maintenance file contents are as follows:

  • To disable monitoring of the HA resource group, create the maintenance file. The file can be empty or can contain the keyword NORESTART.
  • To prevent NNMi from starting during a configuration procedure, the first line of the maintenance file must contain only the single word:
    NORESTART
