Provides the latest time that the group can be failed back to the node identified as its preferred owner node. The following table summarizes the attributes of the FailbackWindowEnd property.
| Attribute | Value |
|---|---|
| Data type | DWORD |
| Access | Read/write |
| Structure | CLUSPROP_DWORD |
| Minimum | 0 (specifies midnight) |
| Maximum | 23 (specifies 11:00 P.M.) or -1 (0xFFFFFFFF for no failback window) |
| Default | -1 ( 0xFFFFFFFF) |
Remarks
The value of the FailbackWindowEnd property can be set to the following values:
| Value | Description |
|---|---|
| 0 to 23 | Indicates 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;
