Multipath for Oracle RAC

Hi Experts,

We are using 2 node RAC with 12.1.0.2 version.

Multipath output in RHEL 7:

PRD-DATA04 (360002ac0000000000000008d0001c9fc) dm-48 3PARdata,VV

size=100G features='1 queue_if_no_path' hwhandler='1 alua' wp=rw

`-+- policy='round-robin 0' prio=50 status=active

 |- 2:0:0:34 sdcg 69:64  active ready running

 |- 1:0:1:34 sdy 65:128 active ready running

 |- 2:0:1:34 sdgv 132:176 active ready running

 `- 1:0:0:34 sdec 128:64 active ready running

I have 2 questions:

1)From above output,Are all these devices physical hard disks or just paths -sdcg,sdy,sdgv,sdec..?

2)Storage admin said,we have 2 HBA cards with dual ports in a host.How many paths can we see if both the HBA cards dual ports are configured..
