My local partitions are detected as multipath device

$multipath -l

`-+- policy='round-robin 0' prio=0 status=active

I added the following lines in multipath.conf so that local partitions are not considered as multipath device

blacklist {
   wwid 3600508b1001c02143bc59c6862d97353
}

Executed the following commands after that .

#service multipathd reload

# multipath -F
Oct 22 12:10:42 | mpathb: map in use
Oct 22 12:10:42 | mpatha: map in use

So , tried rebooting the server , but no luck . Any clues to resolve the issue will be highly appreciated .

Thanks
