Measures reported by HBAStatusTest
A host bus adapter (HBA) is a circuit board or integrated circuit adapter that provides input/output (I/O) processing and physical connectivity between a host system, or server, and a storage or network device. Failure of the host bus adapter may abruptly stop the I/O processing between the host system and the storage/network device. It is therefore necessary to keep a vigil on the status of the host bus adapter round the clock. The HBA Status test helps administrators in this regard.
This test auto-discovers the HBAs in the target environment and for each HBA, reports the status and the count of ports connecting to the target file server. Administrators can also figure out the HBAs that are currently inactive. Using this test, administrators can easily identify the HBAs that are error-prone and are frequently inactive.
Ouputs of the test: One set of results for the target server being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Hba_active |
Indicates whether/not this HBA is active. |
|
If the HBA is active, then this measure will return the value Yes. If the HBA is inactive or not available, then this measure will report a value No.
The numeric values that correspond to these measure values are as follows:
| Measure Value |
Numeric Value |
| No |
0 |
| Yes |
1 |
Note:
By default, the test reports the Measure Values listed in the table above to indicate whether/not this HBA is active. In the graph of this measure however, the same is indicated using the corresponding numeric equivalents only. |
| Hba_status |
Indicates the current status of this HBA. |
|
