About This Document

This document explains how to boot an SP node via manual node conditioning. The advantage of manual node conditioning as opposed to normal node conditioning (netbooting) is that tty connections can assist in troubleshooting problems that may be occurring with the netboot. The normal node conditioning process uses the serial connection during its process, so the tty is unavailable for monitoring.


Booting an RS/6000 SP Node Via Manual Node Conditioning

  1. Configure the SDR for the appropriate bootp response.

    Valid options are dependent upon the version of Parallel System Support Programs (PSSP) you are using:

  2. Type the following, and fill in the appropriate values in the SMIT screen:
    smitty node_data 
    
    ---------------------------------------------------------- 
       Boot/Install/usr Server Information 
       Start Frame                           []   # 
       Start Slot                            []   # 
       Node Count                            []   # 
       OR 
       Node List                             [] 
       Boot/Install Server Node Identifier   [] 
       Network Install Image Name            [] 
       Destination Hard Disk(s)              [] 
       Response from Server to bootp Request <F4 to LIST>     
       /usr Server's Hostname or IP Address  [] 
       Gateway to /usr Server                [] 
       /usr Client Adapter Name                               
       Run setup_server on the Control Workstation?         yes 
    
    ---------------------------------------------------------------

    Select the correct node either by using the Start Frame/Start Slot/Node Count fields OR the Node List field. Use the F4 key to list and select values for Response from Server to bootp Request. All other fields are optional. Be sure the last field is set to yes so the setup_server script will run.

  3. Verify that the node has the correct bootp setting by using the command splstdata -b on the control workstation.

    Sample output:

    node#  hostname  hdw_enet_addr srvr     response    install_disk 
        last_install_image    last_install_time   next_install_image 
    ----------------------------------------------------------------

    NOTE: In the fifth field of this output, node 1 is set to "customize", and nodes 3, 5, and 7 are set to "disk".

  4. Open the Node Front Panel for the selected node via spmon. Type:
       spmon -g 
       "SP" 
       "Display Layouts" 
       Select appropriate frame number and node number 
       Select "Node Front Panel Layout" 
       "Display Node Layout" 
    
  5. Logically power off the node (if it is powered on) with Node Controls.

    NOTE: If this is a high node (SMP), then go to Appendix A. Once that section is complete, proceed to step 11 (skip steps 6-10).

  6. Put the key in Secure mode.

  7. Power on the node with Node Controls.

  8. Put the key in Service mode when the led gets to 200.

  9. Reset the node with Node Controls.

  10. Select Open TTY when the led reaches 260 or 262.

    You should see the following menu. If the menu is not displayed, press the <Enter> key.

    ------------------------------------------------------------ 
    MAIN MENU 
    1.  Select BOOT (Startup) Device

    to "NORMAL" and press "ENTER" to continue booting. 
    99. Return to Main Menu 
    Type the number for your selection, then press "ENTER" 
    (Use the "Backspace" key to correct errors) 
    -------------------------------------------------------------- 
    
  16. Put the key in Normal mode (via the spmon Node Front Panel) and press <Enter> in the tty screen.

    You should see bootp packets sent and received and then tftp packets sent and received.

    Once tftp completes, the next screen you will see depends on the type of network boot that is being done (maintenance, Sysback, diag, and so on).

    When the node conditioning is complete, you should see a login prompt (for install or customize options) or a maintenance menu for the maintenance option.


Appendix A: Special Procedures for High Nodes (SMP)

NOTE: Do NOT use this procedure for wide and thin nodes.

  1. Put the key for the high node in the Service position.

    Use the spmon GUI or issue the command (for node slot 1):

       spmon -key service node1 
    
  2. Open a tty on the node. Use the GUI or issue the command:
       spmon -open node1 
    
  3. At the > prompt, enter sbb and hit <Enter>.
       sbb 
    
  4. Choose option 1, Set Flags.

  5. Ensure that the following two flags are set correctly:
    • Autoservice IPL should be set to Disable.
    • Fast IPL should be set to Enable.

  6. Exit to the > prompt by typing x and then <ctrl> x to break the tty connection.

  7. Power the node on with the GUI or issue the command:
       spmon -p on node1 
    
  8. Open a tty on the node. Use the GUI or issue the command:
       spmon -open node1 
    

    NOTE: If you see the following prompt, hit <Enter>:

       DO YOU WANT TO UPDATE FLASH FROM LINE S2 [y/n] ? n 
    
  9. Choose option 6, SYSTEM BOOT, on the MAINTENANCE MENU screen.

  10. Choose option 1, BOOT FROM NETWORK, on the SYSTEM BOOT screen.
