/proc/mpp
The MPP driver adds a directory in the proc file system that allows us to verify what paths are
active and which devices and LUNs are discovered. Example 17-18 on page 398 shows the
directory structure of /proc/mpp with targets and LUNs that are handled by the MPP driver.
Example 17-18 /proc/mpp/ directory structure
