Reset method of the MSFT_PhysicalDisk class

Resets the health and operational status of the physical disk.


UInt32 Reset(
  [out] String ExtendedStatus


ExtendedStatus [out]

A string that contains an embedded MSFT_StorageExtendedStatus object.

This parameter allows the storage provider to return extended (implementation-specific) error information.

Return value

Success (0)
Not Supported (1)
Unspecified Error (2)
Timeout (3)
Failed (4)
Invalid Parameter (5)
Access denied (40001)
There are not enough resources to complete the operation. (40002)
Cannot connect to the storage provider. (46000)
The storage provider cannot connect to the storage subsystem. (46001)
The storage pool could not complete the operation because its health or operational status does not permit it. (48006)
The storage pool could not complete the operation because its configuration is read-only. (48007)


The exact behavior of this method depends on whether this physical disk belongs to a concrete pool.

If it is a member of a concrete pool, the HealthStatus property should be set to Healthy, and the OperationalStatus property should be set to OK. If any additional errors are detected after Reset, the health and operational statuses should reflect these new errors.

If the physical disk is not a member of a concrete pool, then this method should not only reset the health and operational statuses, but it should return the disk into a state where it is usable as storage for a concrete pool. For example, if a physical disk is missing and then reappears (after it has been replaced), this physical disk is expected to be in the primordial pool only with an operational status indicating its data is either split or corrupt. Calling Reset should clear the physical disk of any data, remove any remaining ties to its former concrete pool, and return the disk to a healthy, usable state.
