Troubleshooting the HMC
Learn how to correct a No connection, Incomplete, Recovery, or Error state on a system managed by an HMC.
- Correcting a No connection state for a managed system
The No connection state can occur when the HMC is not connected, or the connection 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 database. - Recovering partition data on a managed system
Learn how to recover the partition data on your managed system if the partition becomes corrupted. - Restoring profile data
Learn how to read the profile data from the previously backed-up file on the HMC, and load this data to the managed system. - Correcting an Error state for a managed system
The Error state automatically generates a call to the service support center if the automatic call support 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 connection problem between the HMC and a managed system
