Measures reported by SANRAIDPSUTest
The sudden failure of the power supply units of a storage device can cause the device to crash, leading to critical loss of data. To avoid this, you need to keep an eye on the state of each power supply unit of the storage system. This can be achieved using the SANRAIDPSUTest test.
This test auto-discovers the power supply units of the storage system and reports the overall health and operational state of each unit.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| healthState |
Indicates how healthy this power supply unit currently is. |
|
The values that this measure can report and their corresponding numeric values are discussed in the table below:
| Numeric Value |
Measure Value |
| 0 |
OK |
| 1 |
Unknown |
| 2 |
Degraded/Warning |
| 3 |
Minor failure |
| 4 |
Major failure |
| 5 |
Critical failure |
| 6 |
Non-recoverable error |
Note:
By default, this measure reports the Measure Values discussed above to indicate the state of a power supply unit. The graph of this measure however, represents the state of the power supplies using the numeric equivalents only. |
| operationalStatus |
Indicates the current operational state of this power supply unit. |

Note:
By default, this measure reports the Measure Values discussed above to indicate the operational state of a power supply unit. In the graph of this measure however, operational states are represented using the numeric equivalents only. |
| detailedStatus |
Describes the current operational state of this power supply unit. |
|
This measure will be reported only if the API provides a detailed operational state.
Typically, the detailed state will describe why the power supply unit is in a particular operational state. For instance, if the Operational status measure reports the value Stopping for a power supply unit, then this measure will explain why the power supply is being stopped.
