[dm-devel] [PATCH v2] multipath-tools: add more info for NetApp RDAC arrays

[Xose Vazquez Perez]

To use ALUA mode:
"Select operating system:" should be changed to "Linux DM-MP (Kernel 3.10 or later)".

To use RDAC mode:
"Select operating system:" should be changed to "Linux DM-MP (Kernel 3.9 or earlier)".

Add it to prio and hardware_handler.
