Service Request Numbers (HMM

Service Request Numbers (HMM - SRNs)

Service Request Numbers (SRNs)

Service request numbers (SRNs) are generated by the system error-log analysis, system configuration code, diagnostics, and customer problem-determination procedures. SRNs help you to identify the cause of a problem, the failing field-replaceable units (FRUs), and the service actions that might be needed to solve the problem.

The SRN Table

The table in this section lists the SRNs and describes the actions you should do. The table columns are:

SRN The service reference number.
FRU list The FRU or FRUs that might be causing the problem, and how likely it is (by percentage) that the FRU is causing the problem.
Problem A description of the problem and the action you must take.

Abbreviations used in the table are:

DMA Direct memory access FRU Field-replaceable unit PAA P = Adapter port number AA = SSA address (see also 'Finding the Device When No Service Aids Are Available') PCI Peripheral Component Interconnect POST Power-On Self-Test

Using the SRN Table

You should have been sent here from either diagnostics or a START MAP. Do not start problem determination from the SRN table; always go to the START MAP for the unit in which the device is installed.

Locate the SRN in the table. If you cannot find the SRN, refer to the documentation for the subsystem or device. If you still cannot find the SRN, you have a problem with the diagnostics, the microcode, or the documentation. Call your support center for assistance.
Read carefully the 'Action' you must do for the problem. Do not exchange adapters unless you are instructed to do so.
Normally exchange only one adapter at a time. Always use instructions provided with the system unit when exchanging adapters. After each adapter is exchanged, go to MAP 2410 'SSA Repair Verification' to verify the repair.
