REQUEST and the additional sense code will be set to
INVALID FIELD IN CDB. If the PCR bit is set to 0, the log
parameters will not be reset.

The

save parameters (SP) bit determines whether the drive

will save to nonvolatile memory all parameters indentified
as savable in the

disable save (DS) bit of the log page after

a Log Select operation completes. If the bit is set to 1, the
parameters are saved. If the bit is set to 0, the parameters
are not saved.

If the drive does not implement saved parameters for any
log parameter and the SP bit is set to 1, the command is
terminated and a CHECK CONDITION status is issued. The
sense key is set to ILLEGAL REQUEST and the additional
sense code is set to INVALID FIELD IN CDB. If the PCR bit
is set to 0, the log parameters will not be reset.

It is not an error to set the SP bit to 1 and the DS bit to 1. In
this case the parameter values are not saved.

Byte 2

The page control (PC) field defines the type of parameter
values to be selected.

The page control values for the Log Select command are:

Type

Parameter values

00

B

Threshold value

01

B

Cumulative value

10

B

Default threshold value

11

B

Default cumulative value

Bytes 7–8 The

parameter list length field specifies the length in bytes

of the parameter list. If the parameter length is zero, no
pages are transferred.

This is not an error condition.

If the initiator sends page codes or parameter codes within
the parameter list not reserved or not implemented, the
drive terminates the Log Select command and returns a
CHECK CONDITION status. The sense key is set to ILLE-
GAL REQUEST and the additional sense code is set to
INVALID FIELD IN PARAMETER LIST.

If a parameter list length field specifies the length in the
truncation of any log parameter, the drive terminates the
command and returns a CHECK CONDITION status. The
sense key will be set to ILLEGAL REQUEST and the
additional sense code will be set to INVALID FIELD IN CDB.
