Two commands you can use are:

show system redundancy status

show svs connection

If everything looks good you're good to go.  This will ensure the vCenter connection is alive and sync'd up and both VSMs are healthy.

The VSMs do NOT have to be online for VMs to maintain network connectivity.  You can shut down both VSMs and everything will forward as usual.  The only impact to having both VSMs offline is you're not able to create or modify any configuration or create/move virtual ports - including vMotioning a VM from one host to another.  The VEMs will continue to use their last known configuration until at least one VSM comes back online, then it will re-sync up and push any config changes accordingly.
