SCSI Commands
Quantum DLT 8000 Tape System
5-193
REQUEST SENSE Command (03h) (continued)
Table 5–88 Supported Sense Keys
Sense Key
Description
0h
NO SENSE. Check the Filemark/EOM/ILI bits and the Additional Sense
Code/Additional Sense Code Qualifier bytes.
1h
RECOVERED ERROR. This can be caused by rounding of Mode Parameters
on a MODE SELECT, or may report that READ/WRITE error rates are
reaching subsystem specification limits for optimal operation. The device
may still be able to continue to function without any unrecovered errors
for a long period of time, however. No CHECK CONDITION is generated
unless the PER bit of Mode Page 01h is set.
2h
NOT READY. The tape medium is not ready for tape operation
commands. Tape medium might not be present in the drive or may be in
the process of loading or calibrating.
3h
MEDIUM ERROR. An unrecoverable WRITE, READ, or positioning error has
occurred. Detailed device-specific information may be available.
4h
HARDWARE ERROR. The Additional Sense Code / Additional Sense Code
Qualifier fields may present more specific information.
5h
ILLEGAL REQUEST. The Command Descriptor Block or supplied parameter
data had an unsupported or illegal operation specified. Check bytes 15,
16, and 17.
6h
UNIT ATTENTION. Unit Attentions are created after a device reset, if the
medium asynchronously becomes ready to the initiator, if another
initiator changes Mode Parameters, and/or if the firmware is updated.
7h
DATA PROTECTED. The current tape medium is write-protected. This can
be because the Write Protect switch on the cartridge is in its enabled
position or if the tape medium is not the appropriate type (DLTtape I or
DLTtape II), or if a software write protect is issued.
8h
BLANK CHECK. An End of Data or LongGap has been encountered.
Bh
COMMAND ABORTED. This key is generated when a command has been
aborted by the tape drive for some reason. Check the Additional Sense
Code / Additional Sense Code Qualifier bytes.
Dh
VOLUME OVERFLOW. This key indicates that the physical end of tape
medium has been reached during writing. The initiator ignored the End
of Medium condition and continued to write to tape.
Eh
MISCOMPARE. A compare error has occurred during READ by the self-
tests invoked during execution of a SEND DIAGNOSTIC command.
