I think maybe that number 3 and 4 is swapped, but don't take my word for
it. It should be easy to do some tests and figure it out for yourself
by using the "show config" command inside the "multipathd -k" shell with
a few different configuration files.

I found this in an old thread and want to confirm as it will
influence how/what we include in multipath.conf

Is the following order of preference accurate?


*1) Multipaths section (in /etc/multipath.conf)
2) Device section** (in /etc/multipath.conf)
3) Defaults section (in /etc/multipath.conf)4) Internal default (hwtable.c)
*The last two (3 and 4) are the other way round. If there is an entry in hwtable.c, this will take effect.

Thanks … and good to know that hwtable.c
entries take precedence over defaults.

The hardware table is a "device" array.
This array has no precedence over the array fetched from the config
file.

The logic thus looks like ...

1) Multipaths section (in /etc/multipath.conf)
1bis) N/A
2) Device section (in /etc/multipath.conf)
2bis) Internal default (hwtable.c)
3) Defaults section (in /etc/multipath.conf)
3bis) Internal default (config.h)
