DSA edition
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 https://support.lenovo.com/ us/en/documents/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)
• Tape drives (SCSI, SAS, or SATA)
• Memory
• Microprocessor
• Checkpoint panel
• I2C bus
• SAS and SATA drives
• LSI controller
• Broadcom network adapter
• FusionIO adapter
• Intel GPU
• Nvidia GPU
If you are unable to restart the server or if you need comprehensive diagnostics, use DSA Preboot.

Running the DSA Preboot diagnostic programs

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.
