You won't be able to have 2 VIPs with the exact same IP/port combo but since you're doing this manually, you could always have a bogus port specified for the maintenance page VIP and your manual process is simply adjusting the port.

Thank you Buulam    -  there is a part I don't understand -    So 

We have  DNS entry  to sample.com  vip  (config uses nPath) set   to , lets say just to discuss, to  10.0.0.15  with pool of 2 servers that will be down for maintenance.  

So we would create a  New VIP   with  10.0.0.20   and  ???  

how would  we point sample.com  to  new VIP or maint page from new VIP  to respond  to requests to 10.0.0.15  sample.com   ( don't care to much for doing DNS changes since have to deal with  caching - tried that already.) 

 

Many Thanks ...

    During the time when the pools are down, you'd change the 10.0.0.15 to something else and then change 10.0.0.20 in its place

    The new VIP does not need to have a pool attached if you are using a maintenance iRule. It will not show Green "Up" status but it will work.

      Thanks buulam  - we will try that  -  and also will actually help  us , because being that the primary VIP will display the maintenance page  - we can use the temp vip to access the systems  and test before releasing back to users .  

      Thanks again  will let you know ...

        Thank buulam THAT worked !!   Sorry, it took so long our infra F5 team busy on  projects . 

        As far as using the temp  i.p. no test of that yet  BUT  not really not  needed as we can access the servers via IP  to test our  APP. 

        Again thank you  .....  !!!!!!!
