SRM array based Multi site Configuration with array pair recoverpoint sra

Hello,

I need help for configuring my environnement.

I have on my protected site 3 Array unity with 3 recoverpoint appliance, replicated volums on the secondary site with recovepoint and one vnx 5800.

I have already installed on each site one VCenter and SRM VM.

Now, i was able to create "array pair" with one unity and vnx 5800, but i can't  do the same job for the other unity and the vnx 5800

Can someone have an idea?

Components versions:

Vcenter 6.7,

SRM 8.1

Recoverpoint SRA 2.2.3
