For system-specific information about the action that you should take as a result of a message that DSA
generates, see Appendix C "DSA diagnostic test results" on page 1077.
If you cannot find a problem by using DSA, see "Solving undetermined problems" on page 109 for
information about testing the server.
Note: DSA Preboot might appear to be unresponsive when you start the program. This is normal operation
while the program loads.
DSA Preboot
This topic introduces 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 Lenovo XClarity Essentials Bootable Media Creator (BoMC). For more details, see the BoMC User Guide
at . 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.
