Problem with Redundancy Mode

Posted By rgk on 06/25/2010 01:57 AM

 

Dear Hamish,

 

 

As per lil knowledge the ConfigSync should not work if the versions are not the same. But the HA should still works. If there might be some tuning required to make the unit 2 force standby but in case of Primary down it should then become active.

 

 

Please check if there is a possibility because I cannot downgrade or upgrade the version due to some licensing issues.

 

 

Thanks

This is pretty much correct - only time it affects redundancy is with network failover when the transport protocol changes like in version 10 - shouldn't be a big deal here, plus we're using voltage cables as well so both would have to fail to trigger a failover. The active unit never actually does anything right? It remains active even though unit2 also becomes active? Can you check your log entries on unit2 to see if you get anything more descriptive than the typical "going active" type of message? Can you also confirm both your voltage and network cables are securely connected? Might be wise to have unit2 ping unit1's network failover address to see if pings drop when it goes active - shouldn't matter since voltage is in play, but can't hurt to try...
