Hi Steve,
The topology looks fine.Since you have IS5022 switches they are "unmanaged" and are not capable of running an SM (subnet manager) so the other step you would need to take is to start opensm on 1 or 2 (if back SM is wanted) of your hosts compute1/2.The SM is responsible for discovering all IB (Infiniband) devices and assisgning a LID to each then setting up all the possible routing paths to each and every deivce and propogating the routes to each swtich in the fabric.Hope this helps.
