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 ToolsCenter Bootable Media Creator (BoMC). For more details, see the BoMC User Guide at the Bootable Media Creator (BoMC) for Lenovo x86 servers website. 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.
If you are able to restart the server or if you need comprehensive diagnostics, use DSA Preboot.
For more information and to download the utilities, go to the Lenovo Dynamic System Analysis (DSA) website.
