If one pool primary server fails then respective other pools primary server should also fail.

Hi all

 

I am looking for the solution either through Irule or any other feature to solve my issue.

 

I have configured two pools (Pool A and Pool B) and mapped with respective vlan with each pool.

 

Each vlan has 2 server ip address one act as primary server and 2nd as secondary server which i am doing with help of priority.

 

Now customer requirement is if Pool A primary server fails then at same time with help of any technology F5 should bring down Pool B primary server and fall back should be done automatically.

 

Pls someone suggest the solution accordingly.

    You can achieve this by setting ratio to Pool Member(minimum available as per requirement)

     

    Pool

     

    Pool_mem1 : VLAN 1 --> 5 Pool_mem2 : VLAn2 --> 5 POOL_mem3 : VLAN 1 --> 2 POOL_mem4 : VLAn2 -->2

      Hi Samir Pool 1 :- Vlan 1 -- 2 Member configure in Active Passive Pool 1 :- Vlan 2 -- 2 Member configure in Active Passive Requirement :- a) If pool 1 active server fails then traffic should go to passive server:- configure the same with help of priority. b) At the same time pool 2 primary server should also be failed forcefully and traffic should move to secondary server:- Issue open. Need solution for this. Eventually customer is looking for if any pool primary server fails then traffic should move to secondary server in each pool and vice versa. Hope i have cleared your question.

      IanB's suggestion should work - doesn't it ?

    I think you could do this by creating a second monitor for each primary server, configured with an alias address of the other primary server, and then ensure that availability requirement is set to "All" (which is the default value anyway)

     

    Then if pool A's primary goes down, this monitor on pool B's primary would also fail.

     

    I haven't tested this, but I think it would work
