When the abovementioned recovery check function is disabled, failback will not be executed even
though failed paths have recovered from the failures. In such a case, use the -failback option or the
-failbackall option of the spscmd to execute forced failback. (This function is not for Windows Server
2003.)
C:\>spscmd -getlun
*** LogicalUnit #0 ***
X 0: Priority=2, PathNumber=4:0:0:0
> 1: Priority=1, PathNumber=5:0:1:0
C:\>spscmd -failback 4:0:0:0
C:\>spscmd -getlun
*** LogicalUnit #0 ***
> 0: Priority=2, PathNumber=4:0:0:0
1: Priority=1, PathNumber=5:0:1:0

The -failback option executes failback targeting the specified paths. Meanwhile, the -failbackall option
executes failback targeting all failed paths. In both cases, failback will be unsuccessful for the paths yet to
be recovered.
