Properties

IdTypeRangeDescription
Key
InstanceID string
The unique id of the volume statistic. Of the form IBMTSDS:<Volume.DeviceID
Read Only
AbbreviatedID string
The abbreviated ID for the Volume or SE Volume. This ID is NOT globally unique. For example, if the InstanceID of an instance of VolumeStatistics was IBMTSDS:IBM.2107-13ABCDE-100a, then the AbbreviatedID would just be 100a.

This maximum value is valid for BytesRead, BytesWritten, PhysicalStorageBytesRead, and PhysicalStorageBytesWritten.
MaxMS uint64
The maximum value of the IBM extension properties that are in units of Milliseconds. This cannot be declared statically in the mof qualifiers because the value could theoretically vary from device to device.

The cumulative count of all write cache hits (Writes that went directly to Cache). (NormalWriteHits + SequentialWriteHits). The rate at which this counter rolls over cannot be determined, because each of the individual properties being added can roll at different rates. If you need to know the exact point at which which the counters roll, use the specific IBM extension properties and MaxCount.
