Figure 2-8: Path switching

(2) Priority of Switching Destination Paths

Priority of paths varies depending on the architecture of the host machine.

If the architecture of the host is CHRP, the switching destination path is selected based

on four keys. First, the path with the smallest path priority number (first key) is

selected. If there are multiple paths with the smallest path priority number, the order

for selecting a unique path is smallest slot number (second key), smallest CHA port

number (third key), and smallest

PATH_ID value (fourth key).

If the architecture of the host is not CHRP, the switching destination path is selected

based on three keys. First, the path with the smallest path priority number (first key) is

selected. If there are multiple paths with the smallest path priority number, the order

for selecting a unique path is smallest CHA port number (second key) and then

smallest

PATH_ID value (third key).
