MULTIPATH DEVICE PATH is not showing in another Nodes

Paths to multipath device does not show the newly created partition

++++++++++++++++++++++++++++++++++++++

Hi,

During the RAC build, storage team allocated the LUNS to all servers, we are able to see LUNS.

While create luns into one or more primary partition, its not reflecting in other nodes immediately.

[linux01 root]#multipath -ll

same command issue in  other nodes.

[linux02 root]#multipath -ll

[linux01 root]#ll  /dev/mapper/mpatha

it should show the result

[linux02 root]#ll  /dev/mapper/mpatha

it should show the result

else

[linux02 root]#multipath reload  -wherever disk is not showing

[linux01 root]#fdisk  /dev/mapper/mpatha   --make the primary partition

choose  n,p,1,enter,enter ,w

[linux01 root]#partprobe /dev/mapper/mpathap1

[linux02 root]#partprobe /dev/mapper/mpatha

now check 

[linux01 root]# ll /dev/mapper/mpathap1

[linux02 root]#ll /dev/mapper/mpathap1

Now You can go ahead  with ASM disk creation.
