0x800423f8 error in vshadow commands

    Question

  • l develop two vss hardware provider. When l register one to vss service and execute "vshadow -p e:", the result is normal. However when l register the other and execute "vshadow -p e:", the command is giving the following error :

    Creating the shadow (DoSnapshotSet)...
    (Waiting for the asynchronous operation to finish...)
    ERROR: during the last asynchronous operation.
    - Returned HRESULT = 0x800423f8
    - Error text: <Unknown error code>
    - Please re-run VSHADOW.EXE with the /tracing option to get more details

    In the event viewer, error event 12362 generate when abnormal. 
    EVENTVIEWER 12362:
    A Shadow Copy LUN was not detected in the system and did not arrive.

    Operation:
       Exposing Disks
       Locating shadow-copy LUNs
       PostSnapshot Event
       Executing Asynchronous Operation

    Context:
       Execution Context: Provider
       Current State: DoSnapshotSet

    With vsstrace I found that the snapshot destination disk reported the following error log many times when l failed.

           "We find arrived disk \\?\SCSI#Disk&XXXX has no LUN id and is not a snapshot disk arrival."

    When l was successful, the snapshot destination disk reported the following log.

          "{XXXX} is in state 1 and has LUN id {XXXX} and disk no 2."

    My OS is Windows Server 2016 Standard.All my writers are stable and no error.

    What is the possible cause of 0x800423f8 error? Any help is appreciated.

    Thanks
