I can not create a protection group because i don´t see the array pair

Hi

I´m installing the Site Recovery Management 5.1 with vnx5300 EMC -NFS- but i cann´t create the protection group because when i try to create the protection group i can not select array pair because it´s empty.

I configured the sites. status OK.

I configured the mappings.

I configured the array manager in both vCenters.

I enabled the array manager. Status OK  error: 0
