Figure 8-70 REQUEST SENSE Data Cont’d
Valid
A Valid bit of one indicates that the information bytes contain valid information as
defined in the SCSI specification.
Error-Code
A value of 70h indicates a current error – the report is associated with the most recently
received command.
A value of 71h indicates a deferred error – the report is associated with a previous
command and not as a result of the current command.
No other values will be returned.
Segment Number
This byte is always zero.
Filemark
This bit indicates that the current command has read a Filemark.
EOM
This bit indicates that an End-of Medium condition (End of Partition or Beginning of
Partition) exists. The warning is also given by setting the Sense Key to NO SENSE and
the Additional Sense Code Qualifier to End of Partition or Beginning of Partition.
For write-type operations, the drive returns a CHECK CONDITION on any operation
which occurs after detection of the Early Warning EOP marker. The EOM and
Additional Sense Code fields will be set. For read-type operations, the drive does not
return a CHECK CONDITION until the drive encounters the physical EOP.
ILI
The Incorrect Length Indicator bit indicates that the requested logical block length did
not match the logical block length of the data on the tape. Only Read or Verify may
cause this bit to be set.
