Hello I have two 4662-6H2 FS5200 in V9.1.0.1. When trying to create replication policy 2-site, Asynchronous DR

I get the error : CMMVC9805E The command failed because there is insufficient memory available for replication in the specified I/O group on the local system.

Node cansiters memory is 32gb. Can't find requirements.

Anyone can help ?

In this version I can't find Metro/Global MRR , have they been removed ?

Thank you

Sorry, here  https://community.ibm.com/community/user/discussion/policy-based-replication I found the anwers already given by Evelyn Perez.

Somebody knows if it is possible to roll back to V8 (the box is still not in production) ?
