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 medium such as a CD or DVD using ToolsCenter
Bootable Media Creator (BoMC). For more details, refer to the BoMC user guide. You can download the user
guide at:

DSA Preboot includes diagnostic routines that would be disruptive to run within the operating-system
environment (such as resetting devices). 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 Ethernet controller
• Optical devices (CD or DVD)
• Tape drives (SCSI, SAS, or SATA)
• 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 DSA Preboot diagnostic program
Note: The DSA memory test might take up to 30 minutes to finish. If the problem is not a memory problem,
skip the memory test.
To run the DSA Preboot diagnostic program, do the following:
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.
Step 3. When the prompt <F2> Diagnostics is displayed, press F2.
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 symptom while the program loads. The
loading process might 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 the stand-alone memory diagnostic environment, you must restart the server
to access the stand-alone memory diagnostic environment again.
Type gui to display the graphical user interface, or type cmd to display the DSA interactive menu.
Step 5.
Step 6. Follow the instructions on the screen to select the diagnostic tests to run.
If the diagnostic program does not detect any hardware errors but the problem remains during normal server
operation, the diagnostic program error might be the cause. If you suspect a diagnostic program error,
see the information that comes with your program.
