BPV | Bit Pointer Valid |
0The Bit Pointer field is invalid.
1The Bit Pointer field is valid. If the SKSV bit is set then the BPV bit must be set as well.
Bit Pointer | Identifies the bit position of the field in error, whether it is a command descriptor or |
| a command parameter list field. When a |
| the most significant bit of that field. Only valid when the SKSV flag is set. |
|
|
Field Pointer | If SKSV = 1, the interpretation of this field depends on the sense key reported. |
/Drive Error Code | For Sense Key = 5 (ILLEGAL REQUEST), this field represents the Field Pointer, |
| identifying in which byte of the command descriptor or parameter list an error was |
| detected. |
| Note that the drive scans from byte 0 bit 7 of a command or parameter list through |
| to byte n bit 0. The field and bit pointers are set to point to the most significant bit of |
| the field that is in error. See the illegal field check and the parameter list check. |
| For Sense Key = 0 (NO SENSE) or 2 (NOT READY), this field represents the Progress |
| Indication, where the returned value is a numerator that has 65536 (10000h) as its |
| denominator. This reflects the progress being made through the total operation |
| If SKSV = 0, this field represents the Drive Error Code. The top byte of this field will |
| be zero. The bottom byte contains the drive error code associated with the failure of |
| the previous command, or zero in the case of no failure and no appropriate error |
| code. If the drive’s |
| associated with the most recent command, this byte will be set to the error code |
| generated by the failing test. |

| NOTE: Drive error codes are provided for information only; they are intended to |
| assist in product integration and fault diagnosis. The codes should not be relied on |
| by “generic” host drivers, since these are specific to the product. For a list of codes, |
| see Chapter 10 of the Hardware Integration Guide, Volume 1 of the HP |
| Ultrium Technical Reference Manual. |

|
CLN | 0 The drive is OK. |
| 1 The drive requires cleaning. The front panel LEDs will be displaying a “clean |
| me” sequence or message. This bit is cleared to zero after a cleaning |
| cartridge has been used. |
