Question
Manually Performing a Network Boot of an RS/6000 SP PCI Node
Answer
This document describes the procedure for performing a network boot via manual node conditioning on an RS/6000 SP PCI node. Manual node conditioning is a procedure that may be used when the automatic procedures to network boot a node in Perspectives or the command nodecond has failed. Manual node conditioning allows more effective monitoring and troubleshooting during the network boot.
The procedure detailed in this document applies to AIX 5L and PSSP versions 3.4 and 3.5.
Booting an RS/6000 SP PCI node via manual node conditioning
- Configure the System Data Repository (SDR) for the appropriate
bootp_response using one of the following procedures.
Procedure from the command line
- From the command line on the control workstation, enter:
spbootins -r <bootp_response> -l <node_number> -s yes - Choose one of the the following for <bootp_response>: install, migrate, maintenance, or diag (for diagnostic). <node_number> is the number(s) of the node(s) separated by commas.
If the preceding steps are not used, select one of the following procedures according to the appropriate Parallel System Support Programs (PSSP) level.
Procedure using SMIT
-
From SMIT on the control workstation enter smitty server_dialog. The
following screen will display.
--------------------------------------------------- Boot/Install Server Information Type or select values in entry fields. Press Enter AFTER making all desired changes. Start Frame [] # Start Slot [] # Node Count [] # OR Node List [] Response from Server to bootp Request + Volume Group Name [] Run setup_server? yes + --------------------------------------------------- -
In the preceding screen, fill in the following.
For Node_List, enter the number(s) of the node(s) separated by commas. For Response from Server to bootp Request, enter either install, migrate, maintenance, or diag. At the Run setup_server? prompt, enter yes.
For both of the preceding methods, setup_server should complete with a return code of 0, that is rc = 0. If you do not see rc = 0, this could indicate possible NIM errors, which requires fixing before the network boot will work. Contact customer support if you do not see rc = 0.
NOTE: For the following steps 2-5, you may use either Perspectives or the command line. Examples for both Perspectives and the commmand line are included.
- From the command line on the control workstation, enter:
- Power off the node.
- Command line
If the node is still running, enter the following in the command line:shutdown -F spmon -p off node<#><#> is the number of the node. - Perspectives
From Perspectives on the control workstation:- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Highlight the node you are working with.
- Press the Action Menu on the top menu bar and select the Power
Off, Reset, Shutdown, or Fence Nodes option.
- In the Power Off options, choose Power Off.
- In the Shutdown options, choose Shutdown.
- In the Fence options, choose Fence with autojoin.
- Press Apply.
- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Command line
- Open the SP LED panels
- Command line
From the command line on the control workstation, enter:spled & - Perspectives
From Perspectives on the control workstation:- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Click in the Nodes pane.
- Press the Action Menu on the top menu bar and select the LCD and LED Display option.
- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Command line
- Power on the node.
- Command line
From the command line on the control workstation, enter:spmon -p on node<#> - Perspectives
From Perspectives on the control workstation:- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Highlight the node you are working with.
- Press the Action Menu on the top menu bar and select the Power
On or Cluster Power On Nodes option.
- In the Power On options, choose Power On.
- Press Apply.
- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Command line
- Open an slterm/tty connection to the node.
- Command line
From the command line on the control workstation, enter:slterm -w <frame#> <node_slot#><frame#> is the number of the frame and <nodeslot#> is the number of the slot the node is in within the frame.
- Perspectives
From Perspective on the control workstation:- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Highlight the node you are working with.
- Press the Action Menu on the top menu bar and select the Open
TTY option.
- On the SP Perspectives Launch Pad, choose Hardware Perspective.
- Command line
- As the node is coming up, Exxx-type LEDs will display.
On the console, the screen shown below will appear. When you see the
word scsi, there will be a pause. At this pause, press the 1
(the number one) key once.
