Perform this task only if you have a tagged VLAN network configuration having multiple logical network interfaces or a teamed network interface that share the same MAC address.
After you configure the application service group, you must edit the "MACAddress" attribute of the VCS NIC agent and the IP agent.
During the application service group configuration, you are required to select an network adapter for each cluster system and specify the virtual IP address for the virtual server. The application configuration wizard internally retrieves the MAC address of the specified interface and the MAC address of the interface to which the specified IP address is assigned. It then sets these MAC Addresses as the value of the "MACAddress" attribute of the VCS NIC and IP agent respectively.
If the selected interface or the interface to which the specified IP is assigned shares the MAC address with other logical interfaces, then the following issues may occur:
NIC agent may begin to monitor an interface other than the one selected.
The IP agent may assign the specified virtual IP address or the virtual server name to an interface other than the one selected. As a result, the IP agent may monitor an IP address other than the one specified.
As a workaround, use the VCS Java Console to edit the "MACAddress" attribute and specify its value as the interface name instead of the MAC address. You must enter the interface name in double quotes. For example, MACAddress = "InterfaceName"
Notes:
After you specify the interface name as the "MACAddress" attribute value, if you want to use the VCS wizards to modify any settings, then you must first reset the value of the "MACAddress" attribute to the MAC address of the interface. Failing this, the VCS wizard may fail to identify and populate the selected interface. Use the VCS Java Console to edit the attribute values.
If you change the interface name, you must update the "MACAddress" attribute value to specify the new name. Failing this, the NIC resource will go in an UNKNOWN state.
While editing the "MACAddress" attribute to specify the interface name, you must specify the name of only one interface.
