Hardware Management Console (HMC) cannot
be used to manage a managed system, or the
connection to the managed system is failing. If the managed system is operating normally
(no error codes or other symptoms), the HMC
might have a problem, or the connection to the
managed system might be damaged or
incorrectly cabled. Do the following:
1. Check the connections (serial cable)
between the HMC and the managed
system. Correct any cabling errors if found.
If another serial cable is available, connect
it in place of the existing cable and refresh
the HMC graphical user interface. You may
have to wait up to 30 seconds for the
managed system to reconnect.
2. Verify that any connected HMC is
connected to the managed system by
checking the Management Environment of
the HMC.
Note: The managed system must have
power connected and the system running,
or waiting for a power-on instruction (the
“OK” prompt is in the operator panel.)If the
managed system does not appear in the
Navigation area of the HMC Management
Environment, then the HMC or the
connection to the managed system might
be failing.
