Checklist to ensure the proper operation of MultiNICB
For the MultiNICB agent to function properly, you must satisfy each item in the following list:
-
Each interface must have a unique MAC address.
-
A MultiNICB resource controls all the interfaces on one IP subnet.
-
At boot time, you must configure and connect all the interfaces that are under the MultiNICB resource and give them test IP addresses.
-
All test IP addresses for the MultiNICB resource must belong to the same subnet as the virtual IP address.
-
Reserve the base IP addresses, which the agent uses to test the link status, for use by the agent. These IP addresses do not get failed over.
-
If you specify the NetworkHosts attribute, then that host must be on the same subnet as the other IP addresses for the MultiNICB resource.
