IP Address Changes (Post Deployment)
Is it possible (and if so what are the steps needed) to change the management and iDRAC IP addresses of all the hosts in an already deployed and configured VxRail cluster?
TIA!

Please check in Solve Procedure
Based on the VxRail Code level, SolvE desktop will have procedures.
Normally IP change procedures can be found in "How To Procedure" section.
Here is the web version of solve desktop.

We had the need to change both the ESXi management IP and the VLAN backing that. We went round and round on this topic but eventually found it is not supported and requires a fresh rebuild of the cluster in the proper network. Perhaps it is something they will develop a procedure for but at least a few months ago was not supported. Once of the issues is that the ESXi host is joined to the distributed virtual switch. The ESXi management vmkernel is in a distributed port group that has a VLAN ID assigned to it. Their procedure to change the IP includes removing the ESXi host from vCenter, but it still thinks it is part of the DVS and therefore you cannot change the VLAN ID of the management vmkernel. There is probably a way to move each host to a standard local switch, 1 at a time, and then at the end change the DVS port group for management VLAN ID and then join them back to the DVS. It's all that complexity that makes this difficult and to my knowledge is still not supported.
