Boot sequence for the POWER3 SMP High Node

The progress of a node's boot may be observed by watching its LCD change, either using the SP Hardware Perspective or via the command line using the command:

/usr/lpp/ssp/bin/hmmon -Gq frame:slot

If a power on or reset has been performed, the first phase of the node boot is the initialization of the node's Service Processor. This phase has completed once an LCD of the form E000 through E0FF is displayed.

If the node boot stops during this phase, do the following:

1. Check the meaning of the final LCD code in "Appendix A, Messages and Codes " of RS/6000 SP: POWER3 SMP High Node Service Guide.
2. Display the Service Processor logs by performing these steps:
   1. Power off the node from the control workstation.
   2. Open a TTY session to the node.
   3. Hit the return key to go to the Service Processor Main Menu.
   4. Select the System Information Menu.
   5. Select Service Processor Error Logs.

The second phase of node boot for a power on or reset is the initialization of node firmware. This begins with an LCD of Exxx, where xxx may be any value. This phase has completed once the LCD value E175 is displayed. If progress stops during this phase, check the meaning of the final LCD code in "Appendix A, Messages and Codes " of RS/6000 SP: POWER3 SMP High Node Service Guide.

The final phase of node boot is the booting of the AIX operating system. This begins with a bootp request, which is denoted by the E175 LCD code. If the AIX boot has difficulties, record the LCD codes and consult "Appendix A, Messages and Codes" of RS/6000 SP: POWER3 SMP High Node Service Guide for their meaning. When the AIX boot completes, review the AIX error log on the node.
