Make sure that the server has the latest version of the DSA code. To obtain DSA code and the Dynamic

DSA.
DSA editions
Two editions of Dynamic System Analysis are available.
• DSA Portable
DSA 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 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 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 Lenovo ToolsCenter Bootable Media Creator (BoMC). For more details, see the BoMC
Installation and User's 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
If you are unable to restart the server or if you need comprehensive diagnostics, use DSA Preboot.
