PC Server 500 - SCSI error code format
Applicable to: World-Wide
SCSI Error Code Format
This section provides an explanation of the encoded SCSI and non-SCSI Post error codes and detailed information about each code.
Error messages are displayed on the screen as three, four, five, eight, twelve or, thirteen digits. An 'X— in an error message can be any number. The shorter POST errors are highlighted in the Symptom-to-FRU Index. Some digits will represent different information for SCSI errors versus non-SCSI errors. The following figure shows which digits display the shorter POST errors. The figure also defines additional SCSI information.
Notes:
1. Non-IBM device error codes and documentation supersede this list.
2. Duplicate SCSI ID settings will cause misleading error symptoms or messages.
RDDDPLSCB QEET
- Test state
- Error codeExtension
- Qualifier
- Bus (0=internal 1=external)
- Capacity of the device
- Slot number of the device
- LUN (usually 0)
- PUN (SCSI ID #)
- Device Number
- Reserved Digit (usually 0)
As an example, if you have SCSI error code 021050A0 , each digit decodes as follows:
|
Digit |
Information |
|
0 |
Reserved digit(usually 0) |
|
210 |
Device number 210 indicates hard disk |
|

Information |
|
0100 |
0000 |
On systems with NVRAM, SCSI setup data not located, or the checksum did not verify. On systems without NVRAM(Model 50 for example), setup data must be on the 1st hard disk. |
|
0200 |
0000 |
Configuration error. No hard disk found at PUN 6, LUN 0 for 161,162,165 system error path. Might be an unsupported configuration. |
|
0300 |
0000 |
No space available in extended BIOS data area for SCSI data table (possibly too many adapters installed). |
|
0400 |
0000 |
ROM modules not found on adapter (IML based systems only). Running setup might correct it. |
|
0500 |

QEET Errors (other than 0000)
These are specific 'QEET— error codes (preceded by a 'DDD— indicating an adapter).
Note:
A number in slot 'S— indicates an error on the adapter, (or device attached to the adapter) in slot "S." If "S" is 0, suspect the system board.

Q Codes
All error codes with "Q" = 1 are developed using information returned by either an adapter or device. The "Q" value defines the origin of the "EE" code that is reported. Error codes (EE) with "Q" = 4 or 5 may be reported that are not listed here or can actually have a definition other than that given, depending on the device.
