Hi,
Recently I encountered a problem, In certain scenarios that a new local disk was hot plugged, I have no way
to obtain the wwn of the disk in advance, so I can not filter that disk by adding it to blacklists. Actually there
is no need for multipathd to take over local disks in the hot-plugged sceno. And find_multipaths param seems not to be
a perfect way to solve this problem. Is there any way to provide a param in /etc/multipath.conf for mulitpathd to manage
only ISCSI or FC bus disks? In that configuration, path_discovery() will only scan devices which were underline ISCSI bus
or FC bus in sysfs.
Thanks.

Add a rule in the "blacklist section" to exclude ALL,
and then fill the "blacklist_exceptions section" with
the desired devices.
