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 Lenovo XClarity Essentials Bootable Media Creator (BoMC). For more details, refer to the BoMC user guide. You can download the user guide at: the Bootable Media Creator (BoMC) for Lenovo x86 servers website

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.
