3.2.6.4 A Volume Cannot Be Found

  • Artículo

When a client needs to determine the MachineID for a given VolumeID, the client MUST use the FIND_VOLUME message. This message MUST be sent to the server by using a LnkSvrMessage request, as defined in 3.1.4.1. In that request, the client MUST specify a MessageType in the TRKSVR_MESSAGE_UNION of SYNC_VOLUMES, set the Priority value to zero, and set the SyncType field within the TRKSVR_CALL_SYNC_VOLUMES structure to FIND_VOLUME.

For example, this request might be sent if a client is searching for a file and received a TRK_E_REFERRAL error from the LnkSearchMachine call to a DLT Workstation server (as specified in [MS-DLTW]), and where a call to the DLT Central Manager returned TRK_E_NOT_FOUND. The client might then use the VolumeID component of the fileLocationNext parameter of that request in a FIND_VOLUME request as the volume field.

The client MUST also specify the following field in the TRKSVR_SYNC_VOLUME structure:

  •  The volume field MUST be set to the VolumeID whose MachineID is desired.

  •  All other fields of the TRKSVR_SYNC_VOLUME structure MUST be set to all zeros.

See section 3.1.4.4.2 for information about the server processing of this subrequest. See section 3.2.4.4.2 for information about the client's completion of this subrequest.
