DSA editions

This section describes DSA editions.
Two editions of Dynamic System Analysis are available:
• DSA PortableDSA Portable Edition runs within the operating system; you do not have to restart the
server to run it. It is packaged as a self-extracting file that you download from the web. When you run
the file, it self-extracts to a temporary folder and performs a comprehensive collection of hardware and
operating-system information. After it runs, it automatically deletes the temporary files and folder and
leaves the results of the data collection and diagnostics on the server.
If you are able to start the server, use DSA Portable.
• DSA PrebootDSA 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 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:
– ML2 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.
The Lenovo System x3750 M4 Type 8753 server comes with DSA Preboot diagnostics code on the
integrated USB flash memory. Utilities are available to reset and update the diagnostics code on
the integrated USB flash device, if the diagnostic partition becomes damaged and does not start
the DSA Preboot diagnostic programs. For more information and to download the utilities, go to
https://support.lenovo.com/us/ en/documents/LNVO-DSA.
