Measures reported by VrtxStrCntrlTest
VRTX uses a single or dual (for redundancy) Shared PowerEdge Raid Controller (SPERC). This controller which is managed through the CMC allows RAID groups to be configured and then allows for those RAID groups to be subdivided into individual virtual disks that can be presented out to either single or multiple blades.
If a Raid controller or the hardware supporting it experiences critical or fatal issues, the blade servers in the VRTX will not be able to access the virtual disks. If such an outcome has to be averted, administrators must rapidly detect deviations in the performance of the Raid controller and its hardware, and should remedy the situation before it aggravates and affects storage access for the blade servers. This is exactly what the VrtxStrCntrlTest test helps administrators do!
At configured intervals, this test reports the current state of every Raid controller and its hardware, and in the process, warns administrators of their potential failure.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Health_status |
Indicates how healthy this Raid controller currently is. |
|
The values that this measure can report and their corresponding numeric values are discussed below:
| Measure Value |
Numeric Value |
| Other |
1 |
| Unknown |
2 |
| Normal |
3 |
| NonCritical |
4 |
| Critical |
5 |
| NonRecoverable |
6 |
Note:
By default, this measure reports one of the Measure Values listed above to indicate the current health of a Raid controller. In the graph of this measure however, the same is represented using the numeric equivalents only. |
| RollUp_status |
Indicates the current status of the hardware supporting this Raid controller. |

Note:
By default, this measure reports one of the Measure Values listed above to indicate the current health of the controller hardware. In the graph of this measure however, the same is represented using the numeric equivalents only. |
| Cache_size |
Indicates the current size of the cache memory of this Raid controller. |
