VxFlex/ScaleIO v2.6.1 or above: How do we add an additional IP to the MDMs for existing 3 node cluster

Currently we have a VxFlex Test cluster like below. In order to do some testing, it’s required to add another IP interface for MDM.

I referred the article 486641, but “scli -- modify_mdm_ip --primary_mdm_ip ” command indicates as invalid command.

[root@SCLIO1 ~]# scli --query_cluster
