Word 1 - SRC general information

Word 1 is the 8-digit SRC. The SRC includes a 2-byte unit reference code (URC) and variable length configuration and supporting data. The URC is located in the second half of Word 1 of the SRC. This SRC (including the URC) is used during problem analysis. You can identify the type of SRC record by the first digit in Word 1 using Table 38.

Identifying SRCs

The type of SRC can be identified by the first digit in the function 11 data display as follows:

Function display	Description
11 0xxx xxxx to 11 9xxx xxxx	Hardware reported error.
11 Axxx xxxx	Attention or action required. The system is waiting for a
	user action. Example: This type of SRC is displayed on a
	tape IPL if the tape unit is not ready.
11 Bxxx xxxx	Machine check or internal error detected by Licensed
	Internal Code. A Licensed Internal Code component
	detected a system error. The problem could be failing
	hardware or software. Follow the unit reference code tables.
11 Cxxx xxxx	IPL status. Status SRCs are displayed to indicate the
	progression of the IPL. These values can be:
	v C1xx xxxx service processor
	v C2xx xxxx secondary partition
	v C3xx xxxx system processor
	v C5xx xxxx LIC system hardware initialization
	v C6xx xxxx Licensed Internal Code (LIC)
	v	C9xx xxxx OS/400 Operating System
	v	Dxxx xxxx Diagnostic or power down status
11 Dxxx xxxx	General system status. Status SRCs are displayed to indicate
	the status of system functions when the console is not

available. Some of these functions are main storage dump or delayed power off.
