We have two managed servers m1 and m2 in ip1 and ip2 and the admin adm1 is in ip3. We have a scenario where there is a problem with the admin server and it regularly goes down in ip3. All the servers are in individual filesystem. To avoid the loss of control we have already packed and unpacked the admin from ip3 into ip4. When we start the admin in ip4 we dont see the managed servers as running instead we see them as shutdown. Is it possible to control the managed servers from the alternate admin server in ip3 without restarting the managed servers ?.
Managed servers ping the admin URL every 10 seconds until it comes back up. When the admin server's IP has changed
you need a way for the admin URL to allow the managed server to find the restarted admin server on the IP address.
A way to achieve this is by using a DNS name that maps to both IP addresses.
