NimbostratusIrule for redirect when all pool members down, need one for each pool? and what is the standard practice for sorry server?
This is what I have for an iRule to implement when all members of a pool are not available due to maintenance or unplanned outage
when HTTP_REQUEST { if { [active_members EXAMPLETEST_POOL] == 0 ...

NimbostratusHello Everyone,
I am new to F5. I have got a task to make a Strict failover VIP for my client. Referring to your sample irule
when HTTP_REQUEST { if { [active_members [LB::server pool]] == 0 } { HTTP::redirect "http://209.196.27.42/" } }
Please help me understand the meaning of ---HTTP::redirect "http://209.196.27.42/"--- part. When the members of pool in condition is down it will take the VIP down then how would it resolve the redirection. Per my understanding, which I know is wrong, there is no mention of new Pool.

NimbostratusHi Dushyant,
the above example is when your pool members (i.e all backend servers are down ) are not available then redirect all the request to other destination , destination might be other vip or some other source ip.
I understand your concern i.e when pools are down how does vip will take traffic and process the irule .
When Vip is down mean its doesn't mean that it will not do tcp handshake it will still accept the connections but the decision will be made basing on your config on your vip how to process those request .
Thanks ,
Shiva
