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

2.2.2.2 IVdsServiceSAN Data TypesThis section lists data types that are used exclusively by methods in the IVdsServiceSAN interface.2.2.2.2.1 Enumerations2.2.2.2.1.1 VDS_SAN_POLICYThe VDS_SAN_POLICY enumeration defines the set of valid SAN policy values.typedef enum _VDS_SAN_POLICY{VDS_SP_UNKNOWN = 0x0,VDS_SP_ONLINE = 0x1,VDS_SP_OFFLINE_SHARED = 0x2,VDS_SP_OFFLINE = 0x3} VDS_SAN_POLICY;VDS_SP_UNKNOWN: The SAN policy is unknown.VDS_SP_ONLINE: All newly discovered disks are brought online and made WRITABLE. If thedisk is offline, no volume devices are exposed for the disk. If the disk is online, the volumedevices for the disk are exposed. WRITABLE is the normal state for a disk. A disk can also bemade READONLY. If the disk is READONLY, disk data and metadata may be read, but writes tothe disk will fail.VDS_SP_OFFLINE_SHARED: All newly discovered disks not residing on a shared bus arebrought online and made WRITABLE. If the disk is offline, no volume devices are exposed forthe disk. If the disk is online, the volume devices for the disk are exposed. WRITABLE is thenormal state for a disk. A disk can also be made READONLY. If the disk is READONLY, diskdata and metadata may be read, but writes to the disk will fail.VDS_SP_OFFLINE: All newly discovered disks remain offline and READONLY. If the disk isoffline, no volume devices are exposed for the disk. If the disk is online, the volume devicesfor the disk are exposed. WRITABLE is the normal state for a disk. A disk can also be madeREADONLY. If the disk is READONLY, disk data and metadata may be read, but writes to thedisk will fail.2.2.2.3 IVdsServiceIscsi Data TypesThis section lists data types that the IVdsServiceIscsi methods of the IVdsServiceIscsi interfaceuse exclusively.2.2.2.3.1 Structures2.2.2.3.1.1 VDS_ISCSI_SHARED_SECRETThe VDS_ISCSI_SHARED_SECRET structure defines the Challenge-Handshake AuthenticationProtocol (CHAP), as specified in [MS-CHAP], shared secret for an iSCSI initiator.typedef struct _VDS_ISCSI_SHARED_SECRET {[size_is(ulSharedSecretSize)] unsigned char* pSharedSecret;unsigned long ulSharedSecretSize;} VDS_ISCSI_SHARED_SECRET;[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201161 / 360
