IBM SY44-5902-05 manual Multiple SRC entries, Logical address format

Multiple SRC entries

System Licensed Internal Code entries might appear more than once for a single problem. This occurs when the original system reference code is permanent or temporary and additional data is logged at the same time. The additional data can be informational, temporary, an IOP dump, or any other classification. Errors with the same Log ID are generally associated with the same problem. An exception to this would be when the Log ID counter reaches the maximum value and starts over, possibly resulting in a new error being assigned a Log ID that is also used by an existing older entry. Errors that have the same Log ID, but dates that are months or years apart, are indicative of this situation.

Logical address format

Use the logical address (see Figure 48 on page 110) to identify the resource entry. To sort by logical address, select the Analyze log option on the Product Activity Log display. Then select the F9 key (Sort by...) and sort by logical address. For more information on the address, use the address information function (see “Address information function” on page 106).

The logical address format, A/B/C/D-E/F/G/H/J/K, has the following definitions:

AType of I/O bus (transport)

BSystem bus number

CSystem board number (for busses that connect card enclosures)

DSystem card (bus unit) number

-Separates the bus address from the unit address

EUnit address type

FGHJK

Unit address data

The values of F, G, H, J, and K vary, depending on the unit address type (E). Use the following information to determine the Unit address data (FGHJK) representation.

Table 6. Unit address (E) definitions

Unit Address
Value	Unit Address			Unit Address Data
E	Definition	F	G		H	J	K
0	Reserved	-	-		-	-	-
1	Communications	I/O bus	Adapter		Port	Channel	-
2	Storage	I/O adapter	I/O bus		Controller	Device	-
3	Workstation	I/O bus	Adapter		Port	Device	Session
4	Auxiliary Processor	I/O bus	Auxiliary		Adapter	Port	-
			Processor
5	Library	I/O adapter	I/O bus		Library	Controller	Device
6	Cryptography	I/O bus	Adapter		Device	-	-

The Logical address field contains the bus address and the unit address. The bus address describes the hardware bus, board, and card information. The unit address describes the subsystem and identifying data (see Table 6).
