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 1.
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, or the system is making the user aware of an event or condition
that does not need any user action. Examples:
|
| 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:
|
| 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. |
| Note: x = any hexadecimal number
