Measures reported by HpP2kDiskStsTest
If one/more disks in a storage system experience errors or are faulty or have failed, then users will be unable to access the data stored in the disks. Administrators should then be able to rapidly identify which disks are in an abnormal state and determine the reason for the abnormality, so that the problems can be solved quickly. For this purpose, administrators can use the HpP2kDiskStsTest test.
This test reports the current status and health of each disk of the HP P2000 SAN storage system. In addition, this test also reports the LED status of each disk.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| status |
Indicates the current state of this disk. |
|
The values that this measure can report and the their corresponding numeric values are tabulated below:
| Measure Value |
Numeric Value |
Description |
| Error |
0 |
The disk is present but is not detected by the expander. |
| Warning |
1 |
The disk is present but the system is having communication problems with the disk LED processor. For disk and midplane types where this processor also controls power to the disk, power-on failure will result in the Error status. |
| Spun Down |
2 |
The disk is present and has been spun down by the drive spin down feature. |
| Up |
3 |
The disk is present and is properly communicating with the expander. |
| Not Present |
4 |
The disk slot indicates that no disk is present. |
| Unknown |
5 |
Initial status when the disk is first detected or powered on. |
Note:By default, this measure reports the above-mentioned Measure Values while indicating the status of this disk. However, the graph of this measure will be represented using the corresponding numeric equivalents as mentioned in the table above. |
| ledStatus |
Indicates the current state of the LED of this disk. |
|
The values that this measure can report and the their corresponding numeric values are tabulated below:
| Measure Value |
Numeric Value |
Description |
| Fault |
0 |
The disk has a fault. |
| Predictive Failure |
1 |
The disk has a predictive failure. |
| Rebuild |
2 |
The disk's vdisk is being reconstructed. |
| Online |
3 |
The disk is operating normally. |
| Identify the disk |
4 |
The locator LED is illuminated to identify the disk. |
Note:By default, this measure reports the above-mentioned Measure Values while indicating the state of the LED of this disk. However, the graph of this measure will be represented using the corresponding numeric equivalents as mentioned in the table above. |
| health |
Indicates the overall health of this disk. |
|
The values that this measure can report and the their corresponding numeric values are tabulated below:
| Measure Value |
Numeric Value |
| Fault |
0 |
| Degraded |
1 |
| Unknown |
2 |
| OK |
3 |
| Not applicable |
4 |
Note:By default, this measure reports the above-mentioned Measure Values while indicating the health of this disk. However, the graph of this measure will be represented using the corresponding numeric equivalents as mentioned in the table above.
The detailed diagnosis of this measure if enabled, lists the time, name of the disk and the reason for the health of the disk. |
