6 which selects a path with the shortest estimated service time for
10 of in-flight I/Os on a path with the performance value of the path.
11 The performance value is a relative throughput value among all paths
12 in a path-group, and it can be specified as a table argument.
30 other paths having a positive value are available.
36 'A' if the path is active, 'F' if the path is failed.
