           ipmctl.

       -smbus
           Used to specify SMBUS as the desired transport protocol for the current invocation of
           ipmctl.

           Note

       indicated by the "ManageabilityState" property.

           Note
           Some data is endian swapped for human readability.

       DimmID
           (Default) The PMem module identifier.

               revision or is unresponsive (possibly due to a communication interface failure or
               a firmware/hardware error).

           •   Unknown: Unable to determine the PMem module health state. Refer to
               HealthStateReason for HealthState details.

           •   AIT DRAM disabled

           •   CAP Self-Test failure

           •   Critical internal state failure

           •   Performance degraded

           •   CAP Self-Test communication failure
