Thanks very much for the reply

 

 

The master server isn't actually configured as a node on our F5 yet as it doesn't carry traffic - it just manages the traffic carrying nodes.

 

 

 

So if I understand - we could:

 

-add the master server as a node in a pool on F5

 

-run a health monitor to run an external script to check the master server via SNMP get

 

-modify the iRule to include something like

 

if {[active_members slave_pool] < 1} and {[active_members master_pool]{

 

reject

 

 

Does that sound a good plan?

 

 

by the way my next question will be how to build this health monitor to do an snmpget (;

 

 

cheers, Kas
