Class CIM_MediaAccessStatInfo
extends CIM_DeviceStatisticalInformation

Statistics related to reading and writing at a specific MediaAccessDevice, or for a specific StorageExtent. Although the same class is used to represent this data, at the instance level the object holds information for the MediaAccessDevice (independent of the StorageExtent), OR for the Extent (independent of its AccessDevice). Note that this class models the same properties as MediaAccessStatData. The latter, however, uses the simplified key mechanisms of the StatisticalData class.

ResetCounter (uint32)

Method Qualifiers (ResetCounter)

Name	Data Type	Value
Description	string	Method to reset the statistical counters. The method takes one parameter as input - an integer indicating which counter to reset. For this input parameter, 0 indicates all, 1-2 and 5 reset the 'read operation'-related counters, 3-4 and 6 reset the 'write operation'-related counters, and 7-8 reset the seek-related counters. The method returns 0 if successful, 1 if not supported, and any other value if an error occurred. A method is specified so that the Device's instrumentation can also reset its internal processing and counters. In a subclass, the set of possible return codes should be specified in a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' can be specified as a Values array qualifier.
