How to ged rid of duplicate PV?

I am not able to mount /home of 1 TB on my Centos 7.3 VM. Looks like it is complaining about duplicate PVs or UUID.
It is SAN disk coming from Compellent Storage.
If I compare it with other similar and working server, there should not be any /dev/sdc, but I see it here on broken server and can't get rid of that.
Can someone help to review below output and help me fixing it?
