Introduction

The system reference code (SRC) is a sequence of data words (codes) that:

vIdentify a system status

vDescribe a detected hardware, Licensed Internal Code (LIC), or software failure

vDescribe the unit that is reporting the failure and its location.

SRCs can display on the control panel, appear in a system console message, appear in the Primary partition’s console for secondary partitions, or appear in the product activity log (see Chapter 3, “Product Activity Log” on page 99). For details on how SRC information displays on the control panel, see “SRC formats”.

The system gathers information about an error as the system detects the error. The Product Activity Log (PAL) logs and stores the error information. An SRC encodes information used to evaluate or identify a system-detected hardware or software error, failure, or status. The failure information may include the failing condition or part (or unit) that can be exchanged or replaced and its location. The SRC links to the problem determination procedure when the element detecting the failure cannot isolate the failing condition. The SRC link completes the isolation process.

In summary, the SRC provides the first-failure-data-capture information. The customer or support representative uses SRCs during problem determination, repair actions, and verification. The SRC provides a link to the problem determination procedures (hard or soft copy). Use the SRC and the problem determination procedures to isolate the problem.

SRC formats

Models 150, 170, 250, 4xx, 50x, 51x, 530, 53S, 6xx, 7xx, SB1, S10, S20, S30, and S40

The control panel automatically displays the Function 11 word when it shows the SRC (see “Word 1 - SRC general information” on page 193). You can select other words (Functions 12 through 19) by using the control panel Increment (↑), Decrement (↓), and Enter pushbuttons. Some portions of the SRC record might not contain data. SRC records vary in length (up to 36 bytes) and display as described in the following sections.

SRC records show with a -3next to the function number in the Function/Data display on all stage 3 hardware iSeries System Units (for example,

11-3 xxxx xxxx). The -3indicates that the system uses stage three hardware. For
