VDS_SUB_SYSTEM_STATUS enumeration (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Defines the set of object status values for a subsystem.

Syntax

typedef enum _VDS_SUB_SYSTEM_STATUS {
  VDS_SSS_UNKNOWN = 0,
  VDS_SSS_ONLINE = 1,
  VDS_SSS_NOT_READY = 2,
  VDS_SSS_OFFLINE = 4,
  VDS_SSS_FAILED = 5,
  VDS_SSS_PARTIALLY_MANAGED = 9
} VDS_SUB_SYSTEM_STATUS, *PVDS_SUB_SYSTEM_STATUS;

Constants

 
VDS_SSS_UNKNOWN
Value: 0
This value is reserved.
VDS_SSS_ONLINE
Value: 1
The subsystem is working properly.
VDS_SSS_NOT_READY
Value: 2
The subsystem is initializing and not yet ready to work.
VDS_SSS_OFFLINE
Value: 4
The subsystem is unavailable. This value indicates either that the subsystem is disconnected or that it has
failed so severely that it appears to be disconnected.
VDS_SSS_FAILED
Value: 5
The subsystem has failed. This value indicates that the subsystem is not merely
disconnected but rather that it has failed.
VDS_SSS_PARTIALLY_MANAGED
Value: 9
The subsystem is operating in a degraded state. This means that one or more of the subsystem's subcomponents, such as disk drives or controllers, are in a failed state.

Windows Server 2008, Windows Vista and Windows Server 2003:  This value is not supported.

Remarks

The IVdsSubSystem::SetStatus method passes a VDS_SUB_SYSTEM_STATUS value as an argument to set the status of a subsystem, and the VDS_SUB_SYSTEM_PROP structure includes a VDS_SUB_SYSTEM_STATUS value as a member to indicate the current status.

Note  Additional constants might be added to the VDS_SUB_SYSTEM_STATUS enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_SUB_SYSTEM_STATUS enumeration constant.
