Running The Dsa Preboot Diagnostic Programs - Lenovo x3650 M5 Installation And Service Manual

• DSA Preboot
DSA Preboot runs outside of the operating system; you must restart the server to run it. It is provided
in the flash memory on the server, or you can create a bootable media such as a CD, DVD, ISO, USB,
or PXE using the ToolsCenter Bootable Media Creator (BoMC). For more details, see the BoMC User
Guide at http://www.ibm.com/support/entry/portal/docdisplay?lndocid=LNVO-BOMC. In addition to
the capabilities of the other editions of DSA, DSA Preboot includes diagnostic routines that would be
disruptive to run within the operating-system environment (such as resetting devices and causing loss of
network connectivity). It has a graphical user interface that you can use to specify which diagnostics to
run and to view the diagnostic and data collection results.
DSA Preboot provides diagnostics for the following system components, if they are installed:
– Emulex network adapter
– Optical devices (CD or DVD)
– Memory
– Microprocessor
– Checkpoint panel
– I2C bus
– SAS and SATA drives
If you are able to restart the server or if you need comprehensive diagnostics, use DSA Preboot.

Running the DSA Preboot diagnostic programs

Use this information to run the DSA Preboot diagnostic programs.
Note: The DSA memory test might take up to 30 minutes to run. If the problem is not a memory problem,
skip the memory test.
To run the DSA Preboot diagnostic programs, complete the following steps:
Step 1. If the server is running, turn off the server and all attached devices.
Step 2. Turn on all attached devices; then, turn on the server.
When the prompt <F2> Diagnostics is displayed, press F2.
Step 3.
Note: The DSA Preboot diagnostic program might appear to be unresponsive for an unusual
length of time when you start the program. This is normal operation while the program loads. The
loading process may take up to 10 minutes.
Step 4. Optionally, select Quit to DSA to exit from the stand-alone memory diagnostic program.
Note: After you exit from the stand-alone memory diagnostic environment, you must restart the
server to access the stand-alone memory diagnostic environment again.
Step 5. Type gui to display the graphical user interface, or type cmd to display the DSA interactive menu.
Step 6. Follow the instructions on the screen to select the diagnostic test to run.
If the diagnostic programs do not detect any hardware errors but the problem remains during normal server
operation, a software error might be the cause. If you suspect a software problem, see the information
that comes with your software.
