Enter the client address, server address, gateway address (if applicable), andsubnet mask into the Remote Initial Program Load (RIPL). If there is nogateway between the NIM server and the client, set the gateway address to0.0.0.0. To determine if there is a gateway, either ask the system networkadministrator or compare the first 3 octets of the NIM server address and theclient address. If they are the same, (for example, if the NIM server address is9.3.126.16 and the client address is 9.3.126.42, the first 3 octets (9.3.126) arethe same), then set the gateway address in the RIPL field to 0.0.0.0.10. If the NIM server is setup to allow the pinging of the client system, use theping option in the RIPL utility to verify that the client system can ping the NIMserver. Under the Ping utility, choose the network adapter that provides theattachment to the NIM server to do the ping operation. If the ping comes backwith an OK prompt, the client is prepared to boot from the NIM server. If pingreturns with a FAILED prompt, the client does not proceed with the boot.Note: If the ping fails, refer to “Boot problem resolution” on page 153; then,follow the steps for network boot problems.Use the following procedure to temporarily change the system boot list so that thenetwork adapter attached to the NIM server network, is first in the boot list.The system should start loading packets while doing a bootp from the network.Follow the instructions on the screen to select the system console.

If the AIX login prompt displays, standalone diagnostics did not load.Check the following items:v The boot list on the client might be incorrect.v Cstate on the NIM server might be incorrect.v There might be network problems preventing you from connecting to the NIMserver. Verify the settings and the status of the network. If you continue to haveproblems, refer to“Boot problem resolution” on page 153; then, follow the stepsfor network boot problems. After running diagnostics, reboot the system and useBladeCenter management screens to change the boot list sequence back to theoriginal settings.Verify the settings and the status of the network. If you continue to have problems,refer to“Boot problem resolution” on page 153.After running diagnostics from NIM server, change the boot list to the original bootlist.70 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
