Intelligent way to load balance management IP Addresses

Dear all,

 

Overview: I have a situation that I feel is special but then it may not be all that special, so here it is:

 

We had hardware failure few times in the past, so we figured that we could follow the tire rotation strategy where we activate one unit for 3 months and then activate the other unit, so basically each unit would be the active unit twice a year so that the wear and tear is even.

 

I know it sounds crazy, but that’s how we have it setup, which is all good there.

 

The problem: We had the situation many times where one of the guys would login to the standby unit and make changes and then somebody else working on the online unit, and then one of them would overwrite the changes of the other, so I am thinking we’ll need to load balance the management IP Addresses and then apply an iRule that allows the connection the online active unit only and not the online standby unit.

 

What I need: An iRule that I could use when load balancing the management IP Addresses so that the connection is always with the online active unit.

 

 

 

Any help with this is much appreciated.

 

Thanks

    You can't add an irule to the management address. One way would be to manage the bigip via a self-ip. That way you could use the floating self-ip and it'll always use the active one.

     

    Else, you could add a splash page to ask people to check it's the active device when they login. If I recall this is in the Platform section of the GUI, but I may be wrong.
