multipath disk rac

Hello all,

We are build a 2 node cluster(11.2.0.3 on RHEL6) and as part of that i was running the runcluvy.sh script to make sure things are looking good. 
Everything seems to look good, except i am confused on the below part of shared storage.  We had asked for 5 luns of 100GB each and be shared between both node.  I believe we are using EMC SAN and multipath is in use.  The SAN admin asked us to use disk in below format
/dev/mapper/mpathdata1-5 ...but when i run the check i get below output where it says it is happy about the shared storage but the "shareing nodes" on have node2, the san team assured us that those disk are shraed between the noded....

one other thing i noticed the permissions on /dev/mapper/mpathdata1-5 are 777 and is own by root:root, should that be changed to grid:asmadmin ?

 

Am i missing anything here that needs to be configured on SAN end so that  both of the nodes are showing up....

 

## Check was ran from node1
