8.4.7.1 Operation of LOG SELECT
The purpose of the LOG SELECT command is to allow the initiator to modify and
initialize parameters within the logs supported by the device.
There are two ways to initialize the log parameters. First, set the PCR bit in the LOG
SELECT CDB; this clears all parameters. Secondly, individual pages can be cleared
by specifying the log page and the parameter value as the log parameters. The
following pages can be cleared in this manner.

Clearable Log Pages
If multiple pages are sent during this DATA OUT phase, they must be sent in
ascending order according to page code. Otherwise the command will terminate with a
CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and an
additional sense code of INVALID FIELD IN PARAMETER LIST. The same status
will be returned if an unsupported Page Code appears in any header, or if the specified
page cannot be cleared.
