Troubleshooting High Availability Pairs

If the appliances report any failure to enter high-availability mode, the error message will also note the cause. Some issues that can interfere with high-availability mode are:

  • The other appliance is not running.
  • The high availability parameters on the two appliances are not identical.
  • The two appliances are not running the same software release.
  • The two appliances do not have the same model number.
  • Incorrect or incomplete cabling between the appliances does not allow the high availability heartbeat to pass between them.
  • The high availability/Group Mode SSL Certificates on one or both appliances are damaged or missing.
