DESCRIPTION

The meaning of the sense-key specific field depends on which sense key is returned and

 

 

 

 

1

whether the Sense-Key Specific Valid (SKSV) bit is a one. If the sense key field is set to

 

 

 

 

 

ILLEGAL REQUEST and the SKSV bit is one, the sense-key specific field is defined as

 

 

 

 

 

shown in bytes 15 through 17.

 

 

 

 

 

0

If the SKSV bit is a zero, the field is not defined.

 

 

 

 

 

 

 

 

 

16-17

 

 

The field pointer field indicates which byte of the CDB or of the parameter data was in

 

 

 

 

 

error. Bytes are numbered starting from zero as shown in the tables describing the com-

 

 

 

 

 

mands and parameters. When a multiple-byte field is in error, the pointer points to the

 

 

 

 

 

most significant byte of the field.

The format byte defines the format of bytes 20 - 43. See Table 8-15 on page 8-15 to iden-

 

 

 

 

 

tify the format of additional sense.

Byte 19 identifies the error recovery procedure action (ERPA) code. The codes are

 

 

 

 

 

described in Appendix C.

 

 

 

 

 

 

 

 

 

20-43

 

 

The format of sense bytes 20-43 varies depending on whether the sense information is

 

 

 

 

 

from the SIC, FMT, drive, or hardware registers. See Table 8-15 on page 8-15 to identify

 

 

 

 

 

the format of its additional sense.
