A main storage dump is a collection of data from the main
storage in IBM® i.
It can be manually initiated when the system administrator suspects
a system wait or loop, or can be automatically initiated by the server
firmware as the result of a system failure.
Note: Before performing a main storage dump, collect any
reference code information from the control panel or the HMC.
- Verify that no interactive jobs are running.
- On the control panel, select manual mode.
- Use the increment or decrement button to select function
22 (main storage dump).
- Press Enter (the middle button) on the control panel.
- Is 00000000 or FF displayed on the control panel for more
than 30 seconds?
- Yes: The service processor or server firmware is not
responding to a request from the control panel. Contact your next
level of support or your hardware service provider.
- No: An attention SRC A1xx3022 is displayed,
which indicates that function 22 has been selected. Continue with
the next step.
- Perform the following steps:
- Ensure function 22 is shown on the control panel and
press Enter (the middle button) again.
- Switch back to Normal mode and wait for the dump to
complete. If function 22 was selected, the appearance
of an A2D03000 reference code on the console indicates that a successful
user-initiated main storage dump was performed. (A B6xxxxxx reference
code indicates that a successful IBM i initiated main storage
dump was performed.

you have completed a dump, refer to managing dumps.
