How to correct a connection problem between HMC and Managed Systems

No Connection, Incomplete, Recovery, Error, or Failed Authentication state, follow the procedures below.

• Correcting a No connection state for a managed system
  The No connection state can occur when the HMC is not connected, or the handshake with the managed system failed.
• Correcting an Incomplete state for a managed system
  The Incomplete state can occur when the HMC failed to get all of the necessary information from the managed system.
• Correcting a Recovery state for a managed system
  The Recovery state can occur when the save area in the service processor assembly is not synchronized with the HMC.
• Correcting an Error state for a managed system
  The Error state automatically generates a call to the service support center if the function is enabled.
• Correcting a Failed Authentication state for a managed system
  The Failed Authentication state can occur when the HMC access password for the managed system is not valid.
• Correcting a new connection problem between the HMC and a managed system
  Use this procedure if you have a new HMC, a new managed system, or have moved your managed system to a different HMC.
