Description and action This column lists a brief description of the failure that this SRN represents. It also contains instructions as to what to do to continue the problem analysis. Using the SRN list The Service Request Number list is in numerical sequence by SRN. Use the list as follows: 1. Find your SRN in the table. 2. Record the code letter for the Source of SRN (the SRN Firmware error code. column). 3. Record the failing function codes in the order listed. 4. Perform the action shown in the Description and Action column. Notes: 1. If you cannot find SRN information in the Service Request Number list, check for the existence of supplemental material supporting the device for which the SRN was generated. 2. x in an SRN represents any digit or character. 3. If your SRN is not listed, check to see if xxx or xxxx has been used. The -xxx or -xxxx should always be the last SRN identified within a specific prefix. An example would be 950-xxxx. The xxxx is the last digit within the 950 prefix. 4. When replacing a FRU, perform verification of the replacement part using the AIX diagnostics procedure to verify the fix and perform a log-repair action. SRN tables This section lists SRNs 101-711 through 2D02 (AIX) and A00-(x)xxx through A1D-(x)xxx. AIX SRNs 101-711 through 2D02 Replace FRU parts in the order by which the Failing Function Codes are listed. Service request number 101-711 to 101-726 101-888 101-2020 101-2021 Note: Some SRNs in this chapter may have 4 rather than 3 digits after the dash (-). SRN source A A Failing Function Code xxx 210 227 Description and action The system hung while trying to configure an unknown resource. Action: Run standalone diagnostics problem determination procedure. If you still get the same SRN, refer to "Failing Function Codes (FFCs)" on page 141 to find the FFC that matches the last three digits of the SRN. Suspect the device adapter or device itself. Note: xxx corresponds to the last three digits of the SRN. The system does not IPL. Action: System checkout or undetermined problem procedure. The system hung while trying to configure the Infiniband Communication Manager. This problem may be attributed to software. Report this problem to the AIX Support Center. The system hung while trying to configure the Infiniband TCP/IP Interface. This problem may be attributed to software. Report this problem to the AIX Support Center. 110 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
