  • Closed as program error.

Error description

  • When connecting for the first time to the IPMI interface on the
    MQ Appliance using an ipmi utilility's Serial-Over-LAN (SOL)
    function, the connection works correctly.
    
    Subsequent attempts to connect to the IPMI interface using SOL
    result in the following error message.
    
    "SOL payload already active on another session"
    
    Power cycling the appliance does not release the SOL session.
    
    After a successful ipmi tool connection to the MQ Appliance and
    closing the session per the on-screen instructions, the session
    does not close properly resulting in an unusable IPMI state.
    

Local fix

  • From the MQ Appliance console, enter the following commands:
    1. top;diag
    2. bmc-reset cold
    
    After 5 minutes, the BMC will reset itself and restart, and the
    SOL session released allowing another incoming SOL connection.
