A system dump has been initiated on an LPAR and LED code "0c1" is displayed, indicating an I/O error. Where can the administrator find out more about this error?

The HMC Service Guide covers HMC operational procedures and interfaces but does not contain a reference listing for all Power Systems hardware LED diagnostic codes.

The AIX Commands Reference documents AIX operating system commands and has no relevance to hardware-level LED codes generated by the Power Systems firmware.

The HMC Event Log records software and management events captured by the HMC but does not serve as a reference for decoding hardware LED codes displayed on the system panel.

IBM Power Systems reference/LED codes are documented on IBM's support pages, specifically the Power Systems reference codes section accessible through IBM Fix Central and the Power Systems support portal. These codes are hardware-level diagnostic identifiers that are not covered in HMC operational guides or AIX command references, making IBM's official support pages the correct lookup source.
