[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

At any point in the preceding sequence before the percentage completed value in the async object is100, the server MUST update the percentage completed value if forward progress is made duringthe expand operation.3.4.6 Timer EventsNone.3.4.7 Other Local EventsThe server SHOULD track changes in the storage configuration of the computer. These changes maybe due to hardware failures, the administrator changing the hardware configuration, or theadministrator configuring storage objects by using tools such as disk, volume, pack, partition, driveletter, and file system arrivals, removals, and modifications.Note If the server does not track changes in storage configuration, clients MAY be unable toperform configuration operations such as the ones that are specified in this section.3.4.7.1 Disk Pack Arrival (Dynamic Disks)When the server detects that a new disk pack on the system has dynamic disks, the server MUSTadd a disk pack object for it. For information on how to add the pack object, see section 3.4.5.1.1.3.4.7.2 Disk Pack Removal (Dynamic Disks)When the server detects that a disk pack with dynamic disks was removed from the system, theserver MUST remove the corresponding pack object. For information on how to remove the packobject, see section 3.4.5.1.2.3.4.7.3 Pack ModificationWhen the server detects that a pack was modified, for each callback object that is registered in thelist of callback objects, the server MUST call the callback object's IVdsAdviseSink::OnNotify(section 3.3.4.3.1) method by using a VDS_NOTIFICATION (section 2.2.1.3.9) structure thathas the following attributes:•objectType member is VDS_NTT_PACK.•Pack member is a VDS_PACK_NOTIFICATION (section 2.2.1.3.2) with the followingattributes:•ulEvent is VDS_NF_PACK_MODIFY.•packId is the VDS_OBJECT_ID (section 2.2.1.1.3) of the pack object.3.4.7.4 Disk ArrivalWhen the server detects a new disk connected to the system, the server MUST add a disk object forit. For information on how to add a disk object, see section 3.4.5.1.3.3.4.7.5 Disk RemovalWhen the server detects that a disk was disconnected from the system, the server MUST removethe corresponding disk object. For information on how to remove a disk object, see section3.4.5.1.4.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011276 / 360
