Running Diagnostics On The I/O Expansion Module - IBM N6270 Hardware And Service Manual

Running diagnostics on the I/O expansion module

After installing the new or replacement I/O expansion module, you should run
diagnostics on the individual components to ensure that they and the new I/O
expansion module are working properly.
About this task
Before running diagnostics tests on the PCIe cards in your I/O expansion module,
you need to have it cabled according to the following guidelines:
v NIC interfaces must be cabled in a pair-wise manner, with adjacent ports
connected together or connected through a switch. Enter sldiag device show
and then connect the ports to each other, based on the order in which the port
names appear on the console. Do not connect ports e0M and e0P together,
because of the internal switch connection.
Note: On N6200 series systems, the e0M port is the management port (labelled
with a wrench icon) and the e0P port is the private management port (labelled
with a wrench and padlock icon).
v SAS card ports must be connected to storage or connected to the adjacent SAS
ports. If the SAS cards or systems with more than 2 ports are not connected to
storage, connect ports A to B, C to D, and so forth.
v The FC card ports must be connected to storage or the ports terminated with
loopback plugs.
Procedure
1. Reconnect the system to the power source and turn on the power.
2. As the system boots, interrupt the process during the memory test by pressing
Ctrl-C.
The boot process is halted at either the Boot menu or the Loader prompt.
3. Complete the applicable step, depending on where the node halted during the
boot process:
v If the node halted at the Loader prompt, continue with the next step in this
procedure.
v If the node halted at the Boot menu, then perform the following steps to
reach the Loader prompt before continuing with this procedure.
a. Select the Maintenance mode option from the displayed menu.
b. Enter the following command at the prompt: halt
c. Continue with the next step in this procedure.
On the target node, enter the following command at the LOADER prompt:
4.
boot_diags
Important: During the boot_diags process, you must enter y to the following
question before the system will boot to Maintenance mode: WARNING: System
id mismatch. This usually occurs when replacing CF or NVRAM cards!
Override system ID? {y|n} [n] y
Note: You must run this command from the LOADER prompt for
system-level diagnostics to function properly. The boot_diags command starts
special drivers designed specifically for system-level diagnostics.
The Maintenance mode prompt (*>) appears.
5. Enter the following command at the Maintenance mode prompt:
