Measures reported by IbmDsArrayStsTest
The IbmDsArrayStsTest reports the current state of the target storage subsystem, and proactively alerts administrators to failures and space inadequacies experienced by the subsystem.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Array_status |
Indicates the array status. |

Note:
This measure reports the Measure Values listed in the table above to indicate the current state of this array. However, in the graph of this measure, the state is indicated using only the Numeric Values listed in the above table. The details such as logical drive name and its capacity in GB will be available in the detailed diagnosis. |
| Total_capacity |
Indicates the total array capacity. |
GB |
|
| Used_capacity |
Indicates the used array capacity. |
GB |
|
| Percent_free |
Indicates the percentage of capacity that is unused. |
Percent |
Ideally, the value of this measure should be high. A very low value or a value that decreases consistently could be a cause for concern, as it could indicate a steady erosion of space in the array. The lack of storage space is a serious issue that could render the array unavailable for storing any more critical data. You may want to clear space in the array or increase the array capacity. |
