Update Manager and Isolated ESX Service Console Networks

Sometimes you may be required to run your vCenter server that has two network interfaces. One in the network it can be reached for remote desktop access and the other where it has access to the ESX servers in order to manage the VMware hosts. This is sort of a hybrid model of an isolated management network. Where only one host can reach the management ports. One thing to think about in this model is Update Manager by default will not like it. Everything may look ok, but trying to scan a host will fail. Luckily though it is an easy fix.


In the update manager configuration tab change the ip in the picture to the IP accessible by the ESX servers. Then remember to restart the Update Manager services. Now go back and run the ESX scan/stage/remediation.
