a. If you are able to correct the problems(s), click Cancel and go to Step 6 on page 45.b. If you are given a service request code (SRC), perform the steps to service the SRC, then return tothis procedure.c. Otherwise, contact the next level of support.8. After the corrective service has been applied successfully, click Cancel to return.Reconfiguration Procedure for SNI AdaptersAfter the system has booted to the AIX login prompt, log in and verify that the SNI adapters are configuredproperly. On the AIX command line, issue the following command:lscfg | grep sniThere should be two sni adapters identified in the output of the command (represented by their logicaldevice names).If two adapters are not present, issue the following commands at the AIX command line, where x is thefirst SNI port (usually sni0) and y is the second SNI port (usually sni1)ifconfig -d snix down detachifconfig -d sniy down detachrmdev -d -l snixrmdev -d -l sniycfgmgr -vAfter issuing the above commands, reboot the system and verify the presence of two SNI ports.Configuring and Deconfiguring Processors or MemoryAll failures that crash the system with a machine check or check stop, even if intermittent, are reported asa diagnostic callout for service repair. To prevent the recurrence of intermittent problems and improve theavailability of the system until a scheduled maintenance window, processors and memory cards with afailure history are marked ″bad″ to prevent their being configured on subsequent boots.A processor or memory card is marked ″bad″ under the following circumstances:v A processor or memory card fails built-in self-test (BIST) or power-on self-test (POST) testing duringboot (as determined by the service processor).v A processor or memory card causes a machine check or check stop during runtime, and the failure canbe isolated specifically to that processor or memory card (as determined by the processor runtimediagnostics in the service processor).v A processor or memory card reaches a threshold of recovered failures that results in a predictive callout(as determined by the processor run-time diagnostics in the service processor).During boot time, the service processor does not configure processors or memory cards that are marked“bad.”If a processor or memory card is deconfigured, the processor or memory card remains offline forsubsequent reboots until it is replaced or repeat gard is disabled. The repeat gard function also providesthe user with the option of manually deconfiguring a processor or memory card, or re-enabling a previouslydeconfigured processor or memory card.For information about configuring or deconfiguring a processor, see the ProcessorConfiguration/Deconfiguration Menu on page 30. For information about configuring or deconfiguring amemory card, see the Memory Configuration/Deconfiguration Menu on page 32. Both of these menus aresubmenus under the System Information Menu. You can enable or disable CPU Repeat Gard or MemoryRepeat Gard using the Processor Configuration/Deconfiguration Menu.46 Eserver pSeries 655 User’s Guide
