Request Sense
96122 • Revision: F Chapter 6 SCSI Commands 215
Hardware Error, Embedded Software
The library generates a hardware error when an unexpected condition is detected
by the embedded software that controls the SCSI interface. This error is used for
arbitrary limitations of the embedded software.
Hardware Error, Media Load/Eject Failed
The library generates a hardware error when a load or eject fails to complete.
Illegal Request Sense Key
Any illegal parameters in a command descriptor block (CDB) or parameter list for
a particular command generate an Illegal Request sense key (see TABLE 6-88).
In some cases, additional information is available in Byte 15 of the sense data,
which includes the sense-key-specific-value (SKSV) and command/data (C/D)
fields. This information indicates the byte in the command descriptor block or the
parameter list, which is in error.
If available, the SKSV bit in the sense data is set to 1.
See “Request Sense” on page 208 for more information.
