DSA Portable creates a DSA log, which is a chronologically ordered merge of the system-event log (as
the IPMI event log), the integrated management module (IMM) event log (as the ASM event log), and the
operating-system event logs. You can send the DSA log as a file to Lenovo Support (when requested
by Lenovo Support) or view the information as a text file or HTML file.
Note: Use the latest available version of DSA to make sure you are using the most recent configuration
data. For documentation and download information for DSA, see

– Installed hardware, including PCI and USB information
– Light path diagnostics status
– Microprocessor, input/output hub, and UEFI error logs
– Network interfaces and settings
– RAID controller configuration
– Service processor (integrated management module) status and configuration
– System configuration
– Vital product data, firmware, and UEFI configuration
DSA Preboot also provides diagnostics for the following system components (when they are installed):
1. Emulex network adapter
2. IMM I2C bus
3. Light path diagnostics panel
4. Memory modules
5. Microprocessors
6. Optical devices (CD or DVD)
7. SAS or SATA drives
See “Running the DSA Preboot diagnostic programs” on page 166 for more information on running the
DSA Preboot program on your Lenovo server.
