Hardware system reference code formats

Provides system reference code (SRC) format examples.

Notes:

Other formats exist. If necessary, contact your next level of support.
For more information on formats 60–63, see Problem reference code formats detected by Licensed Internal Code.

Table 2. Description of SRC format examples
SRC format	Description
AAAA	Type of I/O bus (see Logical address format — field A).
aaaa	Unit address.
BBBB	System bus number (see Logical address format — field B).
BBBBCcbb	Bus, bus, bus, bus, card, card, and board, board address (direct select address or DSA). For PCI system buses 0001-0003 and 0018-FFFF, the Cc field is a 1-digit multiadapter bridge number and a 1-digit multiadapter bridge function number. For SPD system buses 0004-0017 the Cc field is a two digit card number.
CCCC	System board number (see Logical address format — field C).
cccc cccc	Component reference code. Format 62 varies by component.
DDDD	System Card Number (see Logical address format — field D).
EEEE	Logical address format — Unit Address type — field E.
FFFF	Logical address format — Unit Address type — field F.
GGGG	Logical address format — Unit Address type — field G.
HHHH	Logical address format — Unit Address type — field H.
JJJJ	Logical address format — Unit Address type — field J.
KKKK	Logical address format — Unit Address type — field K.
LMMM	Level indicator plus 3-digit model number (for example, 0001).
lmmm	Level indicator plus 3-digit model number of failing device.
0MMM	Model number of failing device (that is, MMM=001).
MIGV EP	General system status.
NNNN	Number of disk device facilities that are missing.
PPPP	Cause code.
pppp pppp	Programming reference code.
qqqq qqqq	Programming reference code qualifier.
RRRR	Unit reference code (URC).
rrrr	Outboard failing unit reference code (URC).
SAPP UUFF	Unit address.
SSSSSSSS	System Reference Code. This SRC is used to determine why the primary console failed to respond.
ssss	Serial number of failing unit.
TTTT	Type number or card identification number (hexadecimal).
tttt	Outboard failing unit type number (that is, 6607).
uuuu	Unit-specific data.
ww	SRC type.
ZZZZ	Reserved.
