Main storage dump status

During a main storage dump, the control panel shows MSD status SRCs.

During a main storage dump, the control panel shows MSD status SRCs (D1xx 3xxx and C6xx 44xx). For more information on these SRCs, see General status SRCs.

The main storage dump ends successfully if the Main Storage Dump Occurred display appears. The main storage dump ends unsuccessfully if a terminating SRC appears at the control panel.

Terminating System Reference Code (SRC)

For information on using the Hardware Management Console (HMC) to collect reference codes, see Collecting reference codes and system information.

A lit System Attention light indicates dump termination. The terminating SRC displays after the main storage dump completes.

In the case of an automatic dump (system stopping, including a main storage dump), the normal terminating SRC is the one associated with the system error that started the dump.
In the case of a manual dump (Function 22), the normal terminating SRC is a service processor completion code (A1xx 300x or B1xx xxxx):

MSD status	Function performed
11 xxxx xxxx	System terminating SRC. See Error recovery for dumps.
11 A1xx 300x 11 A6xx4404	Main storage dump successful completion. See Copying a main storage dump.
11 B1xx 4998 or 11 B1xx4698 or 11 B2xx5117	A valid main storage dump exists. Perform a complete IPL and try the MSD procedure again.
Note: x can be any hexadecimal character (0 through 9, A through F).
