Measures reported by EMCPvMeVolumeStTest

A volume is a logical subdivision of a vdisk, and can be mapped to controller host ports for access by hosts. A mapped volume provides the storage for a file system partition you create with your operating system or third-party tools. The storage system presents only volumes, not vdisks, to hosts. A faulty or degraded volume therefore can deny hosts access to critical data stored in the storage system. If this is to be avoided, administrators will have to track changes in the state of the volumes and promptly capture the abnormal state of a volume. To achieve this, administrators can use the EMCPvMeVolumeStTest.

For each volume configured in the EMC PowerVault ME storage system, this test reports the current status of the volume, and thus enables administrators to identify those volumes that are in an abnormal state.

Outputs of the test : One set of results for each volume of the storage system being monitored

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
health Indicates the overall health of this volume.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Fault 0
Degraded 1
OK 2
Unknown 3


Note:

By default, this measure reports the above-mentioned Measure Values while indicating the overall health of a volume. However, in the graph of this measure, volume health will be represented using the corresponding numeric equivalents only.

The detailed diagnosis of this measure if enabled, lists the name of the volume and the reason why a volume is in the state that it is in.
