MDM management ip failover between primary mdm and second mdm node
Hello experts
When primary mdm shutdown,can the management ip failover to the second mdm node?If the answer is true,how to configure it ?
In my configuration,there is no management ip ,when primary mdm down, the ip of second mdm is needed to login cli or gui.
Thanks in advance.

As far as i know, the management IP will be based on the IP of the MDM, whichever MDM has become primary, it's IP will be the management IP. If you are managing ScaleIO using CLI, you may always put both IP after the "scli" command ( Eg. scli --mdm_ip IPofMDM1,IPofMDM2).

The MDM switches to the secondary only if there’s a failure (or network problems that behave similarly) or through a command (cli)
If the MDM ownership has changed, try to connect to the IP address of the Secondary MDM.
On Windows and Linux, only the MDM needs a management IP address.
On VMware, all ScaleIO VMs need to have a management IP address as well as another address for the data network, the network on which traffic flows between SDSs and SDCs for read/writes, rebuild, and rebalance.
