Constants

 
VSS_BREAKEX_FLAG_MASK_LUNS
Value: 0x1
The shadow copy LUN will be masked from the host.
VSS_BREAKEX_FLAG_MAKE_READ_WRITE
Value: 0x2
The shadow copy LUN will be exposed to the host as a read-write volume.
VSS_BREAKEX_FLAG_REVERT_IDENTITY_ALL
Value: 0x4
The disk identifiers of all of the shadow copy LUNs will be reverted to that of the original LUNs. However, if any of the original LUNs are present on the system, the operation will fail and none of the identifiers will be reverted.
VSS_BREAKEX_FLAG_REVERT_IDENTITY_NONE
Value: 0x8
None of the disk identifiers of the shadow copy LUNs will be reverted.
VSS_ONLUNSTATECHANGE_NOTIFY_READ_WRITE
Value: 0x100
The shadow copy LUNs will be converted permanently to read-write. This flag is set only as a notification for the provider; no provider action is required. For more information, see the IVssHardwareSnapshotProviderEx::OnLunStateChange method.
VSS_ONLUNSTATECHANGE_NOTIFY_LUN_PRE_RECOVERY
Value: 0x200
The shadow copy LUNs will be converted temporarily to read-write and are about to undergo TxF recovery or VSS auto-recovery. This flag is set only as a notification for the provider; no provider action is required. For more information, see the IVssHardwareSnapshotProviderEx::OnLunStateChange method.
VSS_ONLUNSTATECHANGE_NOTIFY_LUN_POST_RECOVERY
Value: 0x400
The shadow copy LUNs have just undergone TxF recovery or VSS auto-recovery and have been converted back to read-only. This flag is set only as a notification for the provider; no provider action is required. For more information, see the IVssHardwareSnapshotProviderEx::OnLunStateChange method.
VSS_ONLUNSTATECHANGE_DO_MASK_LUNS
Value: 0x800
The provider must mask shadow copy LUNs from this computer. For more information, see the IVssHardwareSnapshotProviderEx::OnLunStateChange method.
