1. Check DRVA Status:
   • Log into vCenter, navigate to JetStream DR → Appliances and validate the DRVA status.
   • Log into vCenter and navigate to the DRVA VM.
     • Ensure the DRVA is powered on and running by logging into DRVA console.
     • If the DRVA is unresponsive, try restarting it.
   • Log into the DRVA console and check if the DRVA service is running.
     
2. Verify Network Connectivity:
   • Ensure the required ports are enabled.
   • Check the network status between the MSA and the DRVA.
   • Ensure no firewalls or network security groups are blockin the DRVA management or data network.
   • Ensure there are no problems with the host IO filter to DRVA communications.
