Exchange/Mirror-view/SRM

Is there anything required to allow SRM with Mirrorview(A) to reliably "protect" exchange.  We are having an issue today where about 50% of the time where the exchange VM will boot and all information stores are fine.  The other half, we have an issue with exchange booting, but the information stores not coming online.

Just trying to understand if there is another peice to the puzzle or application I need to be using such as Replication Manager or something else.

VNX 5300 is being used @ each site
