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 |
| 5 | SCSI ID assigned is 5 |
| 0 | Logical Unit Number (not used, usually 0) |
| A | The device capacity is 60MB (A=60MB) |
| 0 | The device is connected to the internal bus |

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.
| Q | Information |
|---|---|
| 2 | Command error field of command complete status block returned by the adapter |
| 3 | SCSI Status field of the command complete status block or command error field values indicating software problems (<20H) |
| 4 | Sense key value returned by a device |
| 5 | Additional sense byte (byte 12) of sense information from device |
| 6 | Device error code field of command complete status block |
| 7 | Device errors not normally considered an error, but considered an error based on when the code was returned (medium corrupted error on device with non removable media) |
