From: Viswas G <Viswas.G@xxxxxxxxxxxxx>
As a part of drive discovery, driver will initaite the drive spin up.
If all drives do spin up together, it will result in large power
consumption. To reduce the power consumption, driver provide an option
to make a small group of drives (say 3 or 4 drives together) to do the
spin up. The delay between two spin up group and no of drives to
spin up (group) can be programmed by the customer in seeprom and
driver will use it to control the spinup.
