A server that stalls during an initial program load (IPL) of the operating system indicates a problem with the operating system code or hardware configuration. In this case, your only service action is to call your next level of support. If the problem is in the operating system code or hardware configuration, exchanging any hardware FRU will not fix the problem.
Below is reference information that gives a quick overview of the IPL progress codes and the function associated with each.
The mode of the IPL (A, B, or D) determines, in part, which status SRCs are displayed. The different types of IPL use different progress codes, so you will not see all of the progress codes in the table below when you perform an IPL.
The table of IPL status progress codes uses the following format:
For more information about using progress codes, see Using progress codes.
Table 1. IPL status progress codes
| Progress Code | Function/Description |
|---|---|
| C3yx xxxx | System Processor or Main Storage Diagnostic in progress |
| C5yx xxxx | Licensed Internal Code system hardware initialization |
| C500 C92B | Waiting for console device - error condition only if console not found |
| C6xx 1800 | Licensed Internal Code SPCN setup |
| C600 39xx | The typical sequence for an A/B/C mode IPL is 3900, 3910, 3911 (warm IPL only), 3912 (warm IPL only), 3913, 3915, 3917, and then other System Licensed Internal Code IPL progress codes. The others are seen when an IOP flash update occurs, usually on a D mode and possibly on a side (source) switch between A and B or C. |
| C600 3900 | SP transfer control of Bus 1 (BCU Switch) to Licensed Internal Code is Complete and Licensed Internal Code Machine Facilities component is initialized. IPL of Bus 1 is in progress. |
| C600 3910 | Licensed Internal Code has initiated PCI Bus Reset to all Bus 1 devices except the SP |
| C600 3911 | Licensed Internal Code has initiated self test of all Bus 1 devices except the SP |
| C600 3912 | Licensed Internal Code is initiating IPL of the Load Source IOP, waiting for the IOP to signal internal reset complete (Immediate Status Acknowledge Bit set to '1') |
| C600 3913 | Licensed Internal Code is initializing the Load Source IOP messaging functions |
| C600 3914 | Licensed Internal Code has detected a Load Source IOP problem and is resetting the IOP, or the IOP has requested a reset after an internal Flash memory Licensed Internal Code update |
| C600 3915 | Licensed Internal Code has initiated the Load Source IOP self-load |
| C600 3916 | During self-load, the Load Source IOP signalled Licensed Internal Code that it is initiating an internal Flash Memory update or other critical function |
| C600 3917 | The Load Source IOP has completed IPL of its operational load, Licensed Internal Code is waiting for the IOP to report its attached IO resources. This is the last progress code normally displayed regarding Load Source IPL |
