When trying to add an MDM to a cluster or update the IP addresses, you receive the following message:
Error: MDM failed command. Status: Illegal number of IP addresses. The Master MDM, the Slave MDM, and the Tie-Breaker must each have the same number of IP addresses.
It is normally expected that the primary MDM, secondary MDM, and tie-breaker have the same number of IP addresses
Use the following option when issuing the command: --allow_asymmetric_ips
So the full command would be:
scli --add_standby_mdm --mdm_role manager --new_mdm_ip <ip1>,<ip2> --allow_asymmetric_ips
