Is PAV really supported on FBA devices ???
And other than 3390 and 3380(3390 model 2/3 in track-compatibility mode) ECKD types ?
Currently there is no support in the driver for PAV with FBA devices.
But the devices itself are capable of PAV.
If there is no PAV support for FBA devices on Linux, and it looks like it won't be
implemented even in the distant future. The detection code, and the device, could
be deleted from multipath-tools:

Is PAV supported on 9343/9345 (cutype/devtype) ECKD devices?
Thanks.
