Field | Description |
|
|
Sense Key | The SCSI equivalent of Sense Key as defined by the SCSI standard. |
|
|
ASC/ASCQ | The SCSI equivalent of Additional Sense Code (ASC) and Additional Sense Code |
| Qualifier (ASCQ) as defined by the SCSI standard. |
|
|
Sense Key | Definition |
|
|
0h | No Sense. This is an indicator that the drive did not have an error but that the host system may have |
| sent an incorrect command or that a field in the changing parameters information was not correct. This |
| is also an indicator that a request to move the tape past an EOD or a read of a filemark may have been |
| attempted. |
|
|
1h | Recovered Error. The drive had a recoverable error. This is one in which the drive detected something |
| that may not be correct, but that the problem would not prevent the drive from functioning correctly. It |
| may be just an indicator of an event that the drive was able to correct. For example, a Cleaning Requested |
| status shows that the drive requires a cleaning tape, but still functions correctly without it. This sense key |
| is only recorded in the logs if it is a Cleaning Requested condition. |
|
|
2h | Not Ready. The drive is not ready for tape functionality. This is not reported in the drive log pages. |
|
|
3h | Medium Error. The drive was not able to read or write successfully to the tape. Look at the Event Logs |
| and correlate the events with media and system logs to determine if this is due to media or the drive. |
| This sense key is recorded in the drive logs. |
|
|
4h | Hardware Error. The drive has detected an error condition related to the hardware. You need to refer |
| to the Sense Key and ASCQ, along with other event logs to best understand the error. Based on the log |
| information, replace the appropriate component. This sense key is logged each time it is reported. |
|
|
5h | Illegal Request. The requested command had an incorrect parameter defined and you need to review |
| the actual command and parameter to determine what was wrong. This is not logged in the drive logs. |
|
|
6h | Unit Attention. A condition exists that impacts the drive's functionality. Examples include a SCSI Bus |
| reset or a transition from Ready to Not Ready. A reset is required because the Mode Page setting may |
| change after a reset and the host needs to know that. This sense key is not logged in the drive logs. |
|
|
7h | Data Protected. The media currently in the drive is |
| write protect. This sense key is not logged in the drive logs. |
|
|
8h | Blank Check. While reading, writing, or doing a search on the media, the drive encountered a EOD mark |
| or a long gap was detected. A long gap may be the result of a drive stopping the write command without |
| doing the correct command termination. This sense key is not reported in the drive logs. |
|
|
Bh | Aborted Command. Command aborted. Generated when the drive aborts a command. |
|
|
Dh | Volume Overflow. The tape drive has reached the physical EOT and can no longer write data to the tape. |
| This sense key is not reported in the drive logs. |
|
|
Eh | Miscompare. During the drive self tests, the drive detected a data miscompare while executing the |
| internal test. This error would be an indicator that the drive should be returned for repair. |
|
|
ASC/ASCQ | Description | Suggested Action |
|
|
|
0C/00 | Write Error. Drive was not able to | Problem may be the tape cartridge or the drive. |
| successfully write the data to the tape. | If the problem continues, contact customer support. |
