Creating filesystem from HP 3PAR

Hi,

I have a task of creating a few filesystems from external storage (HP 3PAR). The OS is RHEL 5.8.

These are the WWN of the storage devices :

Code:
sht3par02 cli% showvv -host csixdb1 -d

Id Name                  Rd Mstr  Prnt Roch Rwch PPrnt SPrnt PBlkRemain -------------VV_WWN------------- -----CreationTime------ Udid

145 csixdb1-backup_temp.3 RW 0/1/-  ---  ---  ---  ---    --         -- 60002AC000000000000000910001EE00 2019-03-08 10:03:57 +08  145

Attached is the multipath.conf file in the server.

These were the steps I used for the OS to detect the disks :

Code:
modprobe dm-multipath
service multipathd start
multipath -d (this will perform a dry to make sure you are happy with everything, fix anything that appears as a problem)
multipath -v2 (commits the configuration)
multipath -ll
chkconfig multipathd on (make devices are configured after a reboot)
The problem is there is no output for multipath -v2 and multipath -ll :

Code:
[[email protected] ~]# multipath -v2
[[email protected] ~]#
Code:
[[email protected] ~]# multipath -ll
[[email protected] ~]#
Why doesn't the OS detect the multipath device? I need to know the name of the mapped device, then use that device name to create the filesystem using LVM (pvcreate, vgcreate, lvcreate).
