The following new wording added to section 5.10.1 Power conditions overview
is not correct:
If any power condition timer in the Power Condition mode page is enabled,
then that timer shall be stopped on receipt of a command. On completion of
the command, all enabled timers shall be reinitialized based on their Power
Condition mode page values and then started.
That wording conflicts with the following wording in section 6.29 REQUEST
SENSE command:
Upon completion of the REQUEST SENSE command, the logical unit shall return
to the same power condition that was active before the REQUEST SENSE command
was received. A REQUEST SENSE command shall not reset any power condition
timers.
The wording that should have been put into section 5.10.1 Power condition
overview should have been:
If any power condition timer in the Power Condition mode page is enabled,
then that timer shall be stopped on receipt of a command. On completion of
the command, except the REQUEST SENSE command  (see 6.29), all enabled timers
shall be reinitialized based on their Power Condition mode page values and
then started.
Bye for now,
