Measures reported by HPEvaVDiskStsTest
This test reports the current operational state of each LUN on the EVA storage array, and also the current state of the read, write, and mirror caches.
The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Operational_state |
Indicates the current operational mode of this LUN.
|
|
The table below displays the States that can be reported by this measure, and their numeric equivalents:
| State |
Value |
| failed or bad |
0 |
| good, attention, or normal |
1 |
| unknown, not availabe, notinstalled, not_present, unsupported, etc. |
2 |
Note:
By default, this measure reports one of the States listed in the table above. The graph of this measure however will represent the operational state using the numeric equivalents - ‘0’ to ‘2’.
The detailed diagnosis of this measure reports the allocated and requested capacity of each LUN.
|
| Read_cache |
Indicates the current state of the read cache.

Value |
| Disable |
0 |
| Enable |
1 |
| Unknown |
2 |
Note:
By default, this measure reports one of the States listed in the table above. The graph of this measure however will represent the read cache state using the numeric equivalents - ‘0’ to ‘2’.
