Local fix

  • It's a timing issue so the following may, or may not,
    work.
    
    (1) Stop all applications using InfiniBand adapters.
    (2) "rmdev -l ibX" where X is all of the IB interfaces.
    (3) "rmdev -l ibaX" where X is all of the IB adapters.
    (4) "rmdev -l icm".
    (5) Run "cfgmgr" to put all the devices back into the
        Available state.
    

Problem summary

    contain the following text:
    
    "Infiniband ICM Device: IcmOpen: Port is NOT active"
