CIM_MediaAccessStatInfo Superclass: 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.

Parameters (local in grey)
Counter
uint64 RecoveredReadOperations ;
The number of recovered read operations.
Counter
uint64 WriteOperations ;
The number of attempted write operations.
Counter
uint64 ReadOperations ;
The number of attempted read operations.
Counter
uint64 UnrecoverableSeekOperations ;
The number of unrecoverable seek operations.
Counter
uint64 UnrecoverableWriteOperations ;
The number of unrecoverable write operations.
Counter
uint64 RecoveredWriteOperations ;
The number of recovered write operations.
uint32ResetCounter(
The counter to reset.
Qualifiers:ValueMap { "0" , "1" , "2" , "3" , "4" , "5" , "6" , "7" , "8" } Values { "All" , "Read Operations" , "Unrecoverable Read Operations" , "Write Operations" , "Unrecoverable Write Operations" , "Recovered Read Operations" , "Recovered Write Operations" , "Recovered Seeks" , "Unrecoverable Seeks" } IN
uint16 SelectedCounter
)
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.
Counter
uint64 UnrecoverableReadOperations ;
The number of unrecoverable read operations.
Counter
uint64 RecoveredSeekOperations ;
The number of recovered seek operations.

Propagated ( "CIM_LogicalDevice.DeviceID" )
Key
string DeviceID ;
The scoping Device's ID.
MaxLen ( 256 )
Propagated ( "CIM_LogicalDevice.SystemCreationClassName" )
Key
string SystemCreationClassName ;
The scoping System's CreationClassName.

Key
string DeviceCreationClassName ;
The scoping Device's CreationClassName.

Key
string SystemName ;
The scoping System's Name.
MaxLen ( 256 )
Key
string CreationClassName ;
CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
MaxLen ( 256 )
Key
Override ( "Name" )
string Name ;
The Name property, inherited from StatisticalInformation, serves as part of the object key.
string ElementName ;
A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.
Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties.
MaxLen ( 64 )
string Caption ;
The Caption property is a short textual description (one- line string) of the object.
string Description ;
The Description property provides a textual description of the object.
