Sun Remote System Control (RSC) User's Guide

Scenario: An unreliable SIMM in memory bank 2 is causing continuous reboots

  1. Log in to RSC and check the RSC event log.

    You will see repeated server resets in the log.

  2. Examine console logs.

    You will see many SIMM bank 2 errors in the original run log, and eventually a panic message.

  3. Connect to the server console.

    You may see that the system is up now, but receiving periodic SIMM errors.

  4. Log in to the server as root, and halt the system.

  5. Enter the following OBP command to disable SIMM bank 2:

    ok> asr-disable bank2

  6. Reboot the server.

  7. Order new memory for the server.
