| Term | Definition |
|
|
|
| Peripheral Status | Included with the hardware event monitors, the PSM is a |
| Monitor (PSM) | monitor daemon that acts as a hardware status monitor by |
|
| converting events to changes in hardware resource status. |
|
| This provides compatibility with MC/ServiceGuard, which |
|
| uses changes in status to manage cluster resources. Through |
|
| the EMS GUI, the PSM is also used to create hardware |
|
| status monitoring requests. |
|
|
|
| Polling | The process of connecting to a hardware resource at regular |
|
| intervals to determine its status. Any events that occur |
|
| between polling intervals will not be detected until the next |
|
| poll, unless the monitor supports asynchronous event |
|
| monitoring. |

|
|
|
| Resource instance | A specific hardware device. The resource instance is the last |
|
| element of the resource path and is typically the hardware |
|
| path to the resource (e.g., 10_12_5.0.0), but it may also be a |
|
| product ID as in the case of AutoRAID disk arrays. There |
|
| may be multiple instances for a monitor, each one |
|
| representing a unique hardware device for which the |
|
| monitor is responsible. |
|
|
|
| Resource path | Hardware event monitors are organized into classes (and |
|
| subclasses) for creating monitoring requests. These classes |
|
| identify the unique path to each hardware resource |
|
| supported by the monitor. Two similar resource paths exist |
|
| for each hardware |
|
| event monitoring requests, and a status path used for |
|
| creating PSM monitoring requests. |
