Request Sense
226 SL150 Interface Reference Manual Julyl 2017
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 4-125).
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 218 for more information.
