ValueDescription
0 to 23Indicates the hour of day (local cluster time) that the failback window ends.
-1 (0xFFFFFFFF)No failback window exists.

 

Both the FailbackWindowStart and FailbackWindowEnd properties must be specified for a failback window to exist.

  • If a failback window exists, failback will only take place between the hours of FailbackWindowStart and FailbackWindowEnd if the group's preferred node is active or becomes active during that interval.
  • If no failback window exists, failback occurs immediately after the preferred node becomes active.

Examples

The property value portion of a property list entry for FailbackWindowEnd can be set with the following example code:


DWORD FailbackWindowEndData = 12;
CLUSPROP_DWORD FailbackWindowEndValue;

FailbackWindowEndValue.Syntax.dw = CLUSPROP_SYNTAX_LIST_VALUE_DWORD;
FailbackWindowEndValue.cbLength = sizeof(DWORD);
FailbackWindowEndValue.dw = FailbackWindowEndData;
