VDS_SUB_SYSTEM_STATUS enumeration (vds.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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_UNKNOWNValue: 0 This value is reserved. |
VDS_SSS_ONLINEValue: 1 The subsystem is working properly. |
VDS_SSS_NOT_READYValue: 2 The subsystem is initializing and not yet ready to work. |
VDS_SSS_OFFLINEValue: 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_FAILEDValue: 5 The subsystem has failed. This value indicates that the subsystem is not merely disconnected but rather that it has failed. |
VDS_SSS_PARTIALLY_MANAGEDValue: 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.
