Linux service aid ″diagela″The following is an example of the diagela output that is automatically run by theLinux service aid tool kit that has been applied to the system. See “Service aidsand the Linux system error log” on page 40 for more information about these tools.The Linux service aids for hardware diagnostics are separate from the operatingsystem installation and are available for download from the following Web site:http://techsupport.services.ibm.com/server/lopdiagsThis service aid tool kit provides the key tools required to take advantage of theinherent JS20 hardware reliability, availability, and serviceability (RAS) functions.Use the SRN table to determine the description of the problem and the action planfor the SRN provided by the diagela application. For example:diagela: 02/19/2004 18:10:23diagela: Automatic Error Log Analysis has detected a problem.diagela:diagela: The Service Request Number(s) /Probable Cause(s)diagela: (causes are listed in descending order of probability):diagela:diagela: A01-020: CPU internal cache or cache controller errordiagela: Analysis of /var/log/platform sequence number: 3Using the SRN listThe service request number (SRN) list is in numerical sequence. The SRNs listedin the following tables are for all systems and devices for which this version of thediagnostic programs can produce an SRN. The columns in the table are defined asfollows:Service request numberUsually a six-digit number (9333 uses four digits) representing a specific failure of aspecific function.Source of SRNSRN source codes identify the program or procedure that produced the SRN:A The SRN is from a progress code (i.e., 101-254E)B The SRN is from a MAP callout.C The SRN was due to a missing resource at configuration time.D The SRN is from a diagnostic test after complete isolation testing.E The SRN is from a POST failure.F The SRN is from a diagnostic test after partial isolation testing.G The SRN is from the Error Log Analysis program.H The SRN is from a diagnostic message after an 888 sequence.K The SRN is from off-line diagnostics.Failing Function CodesThese numbers represent functional areas of the system unit. The “Failing FunctionCodes (FFCs)” on page 141 identify the FRU that contains this function for eachspecific system unit.Chapter 10. Symptom-to-FRU index 109
