Use this information to run DSA Preboot.
About this task
To run the DSA Preboot diagnostic programs, complete
the following steps:
- If the compute node is running, turn off the compute node and
all attached devices.
- Turn on all attached devices; then, turn on the compute node.
- When the prompt <F2> Diagnostics is displayed,
press F2.
Note: DSA Preboot might appear to be unresponsive for an
unusual length of time when you start the program. This is normal
operation while the program loads.
- Select Quit to DSA to
exit from the stand-alone memory diagnostic program.
Note: After you
exit from the stand-alone memory diagnostic environment, you must
restart the compute node to access the stand-alone memory diagnostic
environment again.
- Enter gui to start the DSA graphical user
interface, or select cmd to display the DSA
interactive menu.
- From the diagnostic programs screen, select the test that you
want to run, and follow the instructions on the screen. For additional
information, see the Dynamic System Analysis Installation and
User's Guide, which is available at the IBM Dynamic System Analysis (DSA) website.
Help for DSA is available. For help about the DSA CLI,

the DSA user interface, press F1. Pressing F1 within a help panel
