3.  (Trained technician only) Make sure that processor 1 and 2 are seated correctly
4.  (Trained technician only) Remove processor 3 and 4 and restart the compute node.
5.  Replace the following components one at a time, in the order shown, restarting the compute node each

time:
a. (Trained technician only) Processor
b. (Trained technician only) System board

Embedded hypervisor is not in the boot list

Complete the following steps until the problem is solved.

1. If the compute node has been installed, moved, or serviced recently, or if this is the first time the

embedded hypervisor is being used, make sure that the device is connected properly and that there is
no physical damage to the connectors.

2. See the documentation that comes with the optional embedded hypervisor flash device for setup and

configuration information.

3. Check

https://static.lenovo.com/us/en/serverproven/index.shtml

to validate that the embedded hypervisor

device is supported for the compute node.

4. Make sure that the embedded hypervisor device is listed in the list of available boot options. From the

management controller user interface, click

Compute node Configuration

➙

Boot Options

For information about accessing the management controller user interface, see the “Opening and Using
the XClarity Controller Web Interface” section in the XCC documentation version compatible with your
server at

5. Check

http://datacentersupport.lenovo.com

for any tech tips (service bulletins) related to the embedded

hypervisor and the compute node.

6. Make sure that other software works on the compute node to ensure that it is working properly.

Server cannot recognize a hard drive

Complete the following steps until the problem is solved.

1. Verify that the drive is supported for the compute node. See

https://static.lenovo.com/us/en/serverproven/

index.shtml

for a list of supported hard drives.

2. Make sure that the drive is seated in the drive bay properly and that there is no physical damage to the

drive connectors.

3. Run the diagnostics tests for the hard disk drives. When you start a server and press the key according

to the on-screen instructions, the LXPM is displayed by default. (For more information, see the “Startup”
section in the LXPM documentation compatible with your server at

https://sysmgt.lenovofiles.com/help/

topic/lxpm_frontend/lxpm_product_page.html

.) You can perform hard drive diagnostics from this interface.

From the Diagnostic page, click

Run Diagnostic

➙

Disk Drive Test

Based on those tests:
a. If the drive fails the diagnostic test, replace the drive.
b. If the drive passes the diagnostic tests but is still not recognized, complete the following steps:

1) Replace the drive (see

“Install a 2.5-inch hot-swap drive” on page 35

for instructions).

2) Replace the hard drive backplane (see

“Install a 2.5-inch drive backplane” on page 34

for

instructions).

4. There are several types of drive, make sure you install the right type drive which is the same as the

compute node setting:

• SATA drive
• SAS drive
