Pinned topic Kernel notifications for RHEL 5 running on 7R2

‏2012-07-20T13:50:08Z |
 Hi everyone,
 
Has anyone had any experience of the following errors whilst running RHEL5 on the new Power Linux platform:
 
we have been receiving errors from the Kernel like the following:

RTAS: event: 2340, Type: Platform Error, Severity: 2
RTAS: event: 2341, Type: Dump Notification Event, Severity: 1

Any pointers to what these codes mean would be helpful.
 
 
Thanks,
Andy

    RHEL 5?   We really generally recommend RHEL 6 for full exploitation of the Power7 servers.
     
    Trolling around for people who might know how to interpret those codes.   Would love to get a pointer documented (saved) here on PowerLinux for future questions on this.

     These are the platform event notifications to OS.
     
    Have you installed IBM Power pack tools ( like ppc64-diag, servicelog packages )? If so, please run "servicelog --dump"  command to get more detail on these events.
     
    Refer below link for IBM Power pack tools.

      Interesting, I tried those commands myself (on a completely different system - just testing the process).
       
      I first "just" installed servicelog, nothing was reported.   Next I installed the ppc64-diag packages, and then servicelog was able to detect and report a number of events (like when we pulled the plug on the power).

      We'll add those packages to the recommended package list when setting up your system.

        Bill,

        >I first "just" installed servicelog, nothing was reported.   Next I installed the ppc64-diag packages, and then servicelog was able to detect and report a number of events (like when we pulled the plug on the power).
         
        Platform errors goes like below :
         
        FW --> kernel --> rtas_errd --> servicelog db <-- servicelog command suite to view/manipulate DB.
         
        rtas_errd daemon --> part of ppc64-diag packages detects FW events / decodes and logs in servicelog db.
         
        servicelog db --> provided by libservicelog package.
         
        servicelog command suite --> set of commands provided by servicelog package to interact with db.
         
         
         > We'll add those packages to the recommended package list when setting up your system.
         
        You may want to include libservicelog (which provides servicelog db and API to interact with DB) as well.

     Hi Andy,
     
    I haven't seen the above error, but I've seen something similar and it was mostly attributed to a 'incomplete' text mode install.
    Did you just do a text mode install?
    If so, some key packages did not get installed, not the least if which is the 'Base' package group. 
     
    Check out Bill's article on how to 'complete' a text mode installation.
    The last step requires you to have the IBM Tool repo enabled. More info on that at the link Vasant posted.

    In tandem with the service log tools that run on Linux , you can also see these RTAS events reflected in the ASM Error/Event logs (ASM->"System Service Aids"->"Error/Event Logs"), and the HMC event logs (Service Management->"Manage Serviceable Events").   Both will give you some additional information that can give some idea of what sort of issue is being reported.   (i.e.  boot failure, configuration issue, hardware failure, power loss detection,...)

     PAPR  says:
     
    'The “Platform Error (224)”, introduced for Version 6, generalizes that the error is identified by the platform and the specific details are encoded in the Platform Event log format itself.
     
    The “Dump notification event (228)” indicates that a dump file is present in the platform and is available for retrieval by the OS. For this type of event notification, the Platform Event Log contains the “Dump Locator” section which contains additional event specific information.'
     
    The dump file should give the actual issue for the platform error. Applicable  As mentioned above, sevicelog or event log in ASM interface should provide the saved dump location.

      You wrote "PAPR says". Could you post a link to and/or a more complete description of the information source? Thanks!

          I'm unable to find a link to it when I search for it online. Do you know where I can get a copy?

            The aforementioned "Power Architecture® Platform Requirements (PAPR)" document is available from http://power.org. One must first join power.org to become a member, and then obtain the document from a members only section of the site. The steps are self-explanatory, beginning here: https://www.power.org/join/joinemp/
