Management console error codes (0xxx, Exxx - Hxxx)

Reference codes are diagnostics aids that help you find solutions to system problems.

Reference codes are diagnostic aids that help you determine the source of a hardware or operating system problem. Using a reference code enables you to find the solution to fix the problem. To use reference codes effectively, you must use them in conjunction with other service and support procedures.

Note: System reference codes (SRCs) often indicate failing items. Some failing items are required to be exchanged in groups until the problem is solved. Other failing items are flagged as mandatory exchange and must be exchanged before the service action is complete, even if the problem appears to have been repaired. For more information, see Block replacement of FRUs.

Block replacement of FRUs

Sometimes, multiple field replaceable units (FRUs) or procedures are called out for replacement by an SRC listed in the service action log (SAL). Each FRU or procedure has a priority, and procedures are always in priority order, from highest to lowest priority. Follow the steps below:

  1. Perform all high priority or mandatory FRU replacements or procedures at the same time (as a block).
  2. If the problem persists after performing the high priority FRU replacements or procedures, then perform the medium priority FRU replacements or procedures one at a time, unless a medium grouping priority is associated with the FRUs or procedures that are called out in the SRC. A medium grouping priority, shown with an A, B, or C, means that you need to perform all the FRU replacements or procedures in that group at the same time (as a block).
  3. Finally, if the problem still persists after performing the medium priority FRU replacements or procedures, then perform the low priority FRU replacements or procedures one at a time.
The priorities of performing the FRU replacements or procedures are shown in the following ways, depending on how you view the SAL.SRC:
  • Advanced System Management Interface (ASMI): The ASMI shows a priority with each callout in the log.
  • Control panel: The control panel shows one of the following priorities with each callout:
    • H = High
    • M = Medium
    • MA = Medium group A
    • MB = Medium group B
    • MC = Medium group C
    • L = Low
  • Hardware Management Console (HMC): In the Service Focal Point on the HMC, the view of the problem data for a serviceable event displays the FRU replacement priority as High, Medium, and so on.
  • Service action log: In the SAL, the Part Action for the FRU in the view of the event shows the replacement priority.
