[Linux-cluster] Local Partitions detected as Multipath Device



My local partitions are detected as multipath device
$multipath -l

mpathb (360014380125d90420000a000003e0000) dm-9 HP,HSV450
size=200G features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=0 status=active
`- 3:0:0:1 sdb 8:16 active undef running
mpatha (3600508b1001c02143bc59c6862d97353) dm-0 HP,LOGICAL VOLUME
size=137G features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=0 status=active
`- 0:0:0:1 sda 8:0  active undef running
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
Zaman
