Unable to create customized multipath device

Hi,
I am testing on iSCSI + multipath, where i have one iSCSI lun assigned to one server.

Code:
mpatha (1IET     00010001) dm-2 IET,VIRTUAL-DISK
size=100M features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=1 status=active
| `- 2:0:0:1 sda 8:0    active ready running
`-+- policy='round-robin 0' prio=1 status=enabled
  `- 3:0:0:1 sdb 8:16   active ready running

and multipath.conf as below ...
Code:
# cat /etc/multipath.conf
defaults {
        user_friendly_names     yes
        udev_dir                /dev
        polling_interval        10
        path_grouping_policy    failover
        getuid_callout          "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
        failback                immediate
        no_path_retry           fail
    verbosity        3
}
multipaths {
       multipath {
              wwid     1IET_____00010001
              alias     qdisk_lun
    }
}


blacklist {
}
