Measures reported by HpP2kVDiskStsTest
A Vdisk is a group of disk drives configured with a RAID level. The HP P2000 G3 system can have a maximum of 16 Vdisks per controller in a dual controller system for a total of 32 virtual disks. In a single controller system, the maximum is 32 virtual disks.
If a user to the storage system is unable to access data in the storage system, it could be because a faulty, degraded, critical, or simply, an offline Vdisk is holding the disk drive that contains the data being accessed. To be able to proactively detect such abnormalities and promptly initiate corrective action, administrators need to periodically check the health of each Vdisk in the HP P2000 storage system. This is where the HpP2kVDiskStsTest test helps.
This test reports the current operational status and the overall health of each Vdisk in the target storage system, so that administrators are instantly intimated of the abnormal state of a Vdisk and are enabled to rapidly initiate remedial action, so that critical data always remains accessible to users.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| status |
Indicates the current status of this Vdisk. |
|
The values that this measure can report and their corresponding numeric values are tabulated below:
| Measure Value |
Numeric Value |
| Offline |
0 |
| Critical |
1 |
| Fault tolerant with down disks |
2 |
| Quarantined critical |
3 |
| Quarantined offline |
4 |
| Quarantined with down disks |
5 |
| The vdisk is stopped |
6 |
| Unknown |
7 |
| Fault tolerant and online |
8 |
| The vdisk is online |
9 |
Note:By default, this measure reports the above-mentioned Measure Values while indicating the status of this Vdisk. 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 Vdisk. |
|
The values that this measure can report and the states they indicate are tabulated below:
| State |
Numeric Value |
| Fault |
0 |
| Degraded |
1 |
| OK |
2 |
| Unknown |
3 |
Note:By default, this measure reports the above-mentioned states while indicating the health of this vdisk. However, the graph of this measure will be represented using the corresponding numeric equivalents of the states as mentioned in the table above.
The detailed diagnosis of this measure if enabled, lists the name of the vdisk and the primary reason why the health state of that vdisk is what it is. |
