Manual vNIC failover via HMC CLI

We'd like to ability to do manual vNIC failovers via the HMC CLI as this is our preferred means of performing scheduled maintenance on our POWER systems.

    Marking as delivered since the requested feature is already available as per the comments in previous sequence.

    When I opened a case asking this question I was told it was not possible to manually failover via command line. However, that's not the case per the knowledge center page for the chhwres command:

    Make the backing device, with logical port ID 27004001, for the virtual NIC in slot 3 of the partition lp4 active:

    chhwres -m sys1 -r virtualio -o act --rsubtype vnicbkdev -p lp4 -s 3
    --logport 27004001

    So what we've been able to do is generate a spreadsheet of the appropriate failover commands to do this quickly and manually when performing maintenance. This RFE can be closed.

    Hi David,

    We have evaluated this RFE and had some question.

    1. Is the use case here that a SRIOV Physical Adapter is being taken down for maintenance and hence need for vNIC backing device change ?
    2. Is vNIC failover enabled in this setup such that there are 2 backing devices from 2 different physical adapters?
    3. If vNIC failover is not enabled, can vNIC failover be enabled to handle such a scenario ?
