2.
If you are attempting to boot from the network:
a.
Make sure that the network cabling to the IBM Flex System Enterprise Chassis network switch is
correct.
b.
Check with the network administrator to make sure that the network is up.
c.
Verify that the compute node for your system is running and configured to respond to your
system.
d.
Turn the compute node power off, and then turn it on to retry the boot operation.
e.
If the boot still fails, replace the system-board and chassis assembly.
3.
If you are attempting to boot from a hard disk drive:
a.
Verify that the hard disk drive is installed.
b.
Select the hard disk drive as the boot device.
c.
Reload the operating system onto the hard disk drive if the boot attempts from that disk continue
to fail.
d.
If you are not able to load the operating system, replace the suspected hard disk drice
e.
Replace the system board, and then retry loading the operating system.
Troubleshooting by symptom
Use the troubleshooting tables to find solutions to problems that have identifiable symptoms.
About this task
If these symptoms relate to shared IBM Flex System Enterprise Chassis resources, see “Solving shared
IBM Flex System Enterprise Chassis resource problems” on page 482. If you cannot find the problem in
these tables, see “Running the diagnostics program” on page 444 for information about testing the
compute node.
If you have just added new software or a new optional device and the compute node is not working,
complete the following steps before using the troubleshooting tables:
1.
Remove the software or device that you just added.
2.
Run the diagnostic tests to determine whether the compute node is running correctly.
3.
Reinstall the new software or new device.
Intermittent problems
Identify intermittent problem symptoms and corrective actions.
v
Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v
See Chapter 7, “Parts listing for IBM Flex System p270 Compute Node,” on page 95 to determine which
components are CRUs and which components are FRUs.
v
If an action step is preceded by “Trained service technician only,” that step must be performed only by a
trained service technician.
Symptom
Action
Intermittent connectivity
problems (single compute node)
1.
Make sure that the network cables are correctly connected in the switch
module ports and that the switch module is correctly seated.
2.
Update the network interface card (NIC) device driver or the storage device
controller device driver.
3.
See the documentation for the I/O module for resolving connectivity problems.
