RHQ storage node issue in cluster - Down state

We are trying to get the storage nodes connected in the cluster with 2 VMs, 1 instance on each VM. We end up seeing 1 up in Normal status, the other in Down. Here is the error in the logs:

10:59:19,324 ERROR [org.rhq.server.metrics.MetricsServer] (StorageClientThreadPool-0) An error occurred while inserting raw data Measuremen tDataNumeric[name=Native.MemoryInfo.actualFree, value=1.2627976192E10, scheduleId=11495, timestamp=1403017146580]: com.datastax.driver.core .exceptions.UnavailableException: Not enough replica available for query at consistency ONE (1 required but only 0 alive)
