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

tape IPL if the tape unit is not ready.
11 Bxxx xxxx Machine check or internal error detected by Licensed
