Suppress Events and Alarms for Devices in Maintenance or Hibernation

When a model is in maintenance or hibernation mode, no events are processed for that model. That includes events that would typically clear an alarm on the model, as well as events that would create an alarm. For example:
casp941
When a model is in maintenance or hibernation mode, no events are processed for that model. That includes events that would typically clear an alarm on the model, as well as events that would create an alarm. For example:
If a link_down event generated an alarm on a device model before the model being placed in maintenance mode and a link_up event occurred while the device model is in maintenance mode, the SpectroSERVER does not clear the alarm since the link_up event is not processed.
In this example, the SpectroSERVER would not resume normal management traffic to the maintenance modeled device until you manually disable the maintenance mode option for this device in the Component Detail panel.
If, in this example, the modeled device was placed in hibernation mode instead of maintenance mode, the SpectroSERVER would have to make a set of successful communication attempts to the device before it could resume normal management traffic with the device.
Secondary Alarms and Devices in Maintenance Mode
You can configure CA Spectrum to show or hide secondary alarms when a device is in maintenance mode. The ‘Show Secondary Alarms When Device is in Maintenance’ parameter in the Set Preferences dialog controls this behavior. If this parameter is enabled, secondary alarms are shown when a device is in maintenance mode.
You cannot show or hide secondary alarms for devices in hibernation mode.
The 'Show Secondary Alarms' option is disabled by default. Secondary alarms are hidden when a device is in maintenance mode and are shown later when the device is taken out of maintenance mode. 
: The ‘Show Secondary Alarms' setting only applies when the primary and secondary alarms are enabled in the Alarm Filter settings in the Set Preferences dialog.
Show Brown Alarms for Interfaces and Applications
You can display brown alarms for interfaces and applications that have inherited maintenance or hibernation mode from the device model by using the CA Spectrum Command Line Interface (CLI).
  • To generate brown alarms on interface models that have inherited maintenance mode, set the device model attribute 0x00012a7a (rollMMAlarmToIF) to TRUE.
  • To generate brown alarms on application models that have inherited maintenance mode, set the device model attribute 0x00012a7b (rollMMAlarmToApp) to TRUE.
