The following error message might be displayed when you attempt to add an IPMP group:
*ipadm: cannot add net0 to ipmp0: Underlying interface has addresses managed by dhcpagent(1M)*
This message is displayed because you cannot add an IP interface with an address that is managed by dhcpagent into an IPMP group. As a workaround, disable the DHCP and/or stateful address configuration on net0 before adding it to the IPMP group.
