The server comes with the Dynamic System Analysis (DSA) Preboot diagnostic
program stored in the integrated USB memory on the server. DSA collects and
analyzes system information to aid in diagnosing server problems, as well as
offering a rich set of diagnostic tests of the major components of the server. DSA
creates a DSA log, which is a chronologically ordered merge of the system-event
log (as the IPMI event log), the Integrated Management Module II (IMM2) 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 or view the information as a text file or
HTML file.
