Control
The LOG SELECT command causes log data on the drive to be reset to its default
value or to be set to an initiator-specific value.
If the Parameter Code Reset (PCR) flag is set, the Parameter List Length is 0, and
the Page Control (PC) field is 01b or 11b, then all the logs on the drive that can be
reset are reset to their default values.
If the Parameter Code Reset (PCR) flag is set, the Parameter List Length is 0, and
the Page Control (PC) field is 00b or 10b, then no action is taken and Good status
is returned.
If the Parameter Code Reset (PCR) flag is clear, the Parameter List Length is not 0,
and the Page Control (PC) field is 01b or 11b, then data is sent from the server and
is written to the indicated logs, provided those logs are writable.
If the preceding conditions do not apply, Check Condition status is returned. The
Sense Key is set to Illegal Request and the ASC/ASCQ is set to Invalid Field in
CDB (2400).
The Save Page (SP) flag is not supported and must be set to 0.
