If you cannot find a problem by using DSA, see “Solving undetermined problems” on page 116 for
information about testing the server.
Note: DSA Preboot might appear to be unresponsive when you start the program. This is normal operation
while the program loads.
Make sure that the server has the latest version of the DSA code. To obtain DSA code and the
Dynamic System Analysis Installation and User's Guide , go to https://support.lenovo.com/us/

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 IBM 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:
– 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.
