MPIO_TIMERS_COUNTERS WMI Class
A WMI client uses the MPIO_TIMERS_COUNTERS WMI class to query MPIO for all global timer values.
class MPIO_TIMERS_COUNTERS
{
[key, read]
string InstanceName;
[read] boolean Active;
//
// Flag indicating if automatic path verification must be performed every
// N seconds (where N depends on the value set in PathVerificationPeriod).
// Type is boolean and must be filled with either 0 (disable) or 1 (enable).
//
[WmiDataId(1),
read, write,
Description("Enable/Disable Auto Path-Verification.") : amended
] uint32 PathVerifyEnabled;
//
// This timer is specified in seconds. The default is 30 seconds
// and its max allowed is MAXULONG. It controls the periodicity
// for path verification.
//
[WmiDataId(2),
read, write,
Description("Path Verification Timer.") : amended
] uint32 PathVerificationPeriod;
//
// This timer is specified in seconds. The default is 20 seconds
// and its max allowed is MAXULONG. It controls the amount of time
// that the pseudo-LUN will continue to be in memory, even after
// loosing all its paths.
//
[WmiDataId(3),
read, write,
Description("PDO Remove Timer.") : amended
] uint32 PDORemovePeriod;
//
// The number of times a failed I/O will be retried if DsmInterpretError
// requests a retry. The default is set to 3.
//
[WmiDataId(4),
read, write,
Description("Request Retry Count (Max 500)") : amended
] uint32 RetryCount;
//
// This value is specified in seconds. The default is 1 second. It
// controls the interval of time after which a failed request is
// retried (after the DSM has decided so).
//
[WmiDataId(5),
read, write,
Description("Retry Interval (seconds) (Max MAXULONG)") : amended
] uint32 RetryInterval;
};
When this class definition is compiled by the WMI tool suite, it produces the MPIO_TIMERS_COUNTERS data structure. There are no methods associated with this WMI class.
