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-protected. This can be a hardware or software

 

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.

Suggested Action

 

 

 

0C/00

Write Error. Drive was not able to

Problem may be the tape cartridge or the drive.
