The following table lists the states that detectors may report to the base monitor:
State | Description |
|---|---|
Faulted | Error condition encountered. The error may have occurred in the resource, in one of its children, or during script processing. |
Offline | Disabled, not ready for use. The scripts have successfully disabled the resource. |
Online | Enabled, ready for use. All required children are online, and no errors were encountered while scripts were processed. |
Standby | Ready to be quickly brought Online when needed. |
The following table lists additional resource states that may be displayed in the Cluster Admin GUI or by hvdisp:
State | Description |
|---|---|
Deact | Disabled for the purpose of maintenance. |
Inconsistent | Applies to userApplication objects only. The object is Offline or Faulted, but one or more resource objects in its graph have their ClusterExclusive attribute set to 1 and are Online or Faulted. |
OfflineFault | Fault that occurred in the past has not yet been cleared. |
Unknown | No information is available. Reported before object initialization is completed. |
Wait | Under state transition. |
Warning | Some warning threshold has been exceeded. Note that this state is reported only for selected resources. |
Maintenance | Manual, temporary mode of operation in which the state of an application is decoupled from the states of its dependent resources. This allows, for example, a file system to be taken offline for backup without disturbing the state of its parent application. An application in maintenance mode is usually marked with its intended status. The intended status is the status just before the start of maintenance mode.The maintenance mode intended statuses are Maintenance- Online,Maintenance-Offline, and Maintenance- Standby. |
The interpretation of Offline and Faulted may depend on the resource type. For instance, a mount point resource can be either Online (mounted) or Offline (not mounted); in this case, the detector would never report the Faulted state. On the other hand, a detector for a physical disk can report either Online (normal operation) or Faulted (input or output error); it would never report Offline.
