"One of two modes for I/O paths. A standby path is held in reserve.
Being set to standby does not mean a path will not be used. Rather,it
means that the weight of the path is heavily adjusted to preclude its
use in normal operations. A standby path still can be selected if it is
the best path for a request. Path mode is set with powermt set mode."
If you try to configure a Channel Group, a path may have been set to "standby".
