• 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 IBM ToolsCenter Bootable Media Creator (BoMC). For more details, see the BoMC User Guide

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
If you are unable to restart the server or if you need comprehensive diagnostics, use DSA Preboot.
