SCSI Motor Spin-Up

When power supply is unable to provide sufficient current to start
all the hard drives and controllers at once, spinning-up hard drives
in a sequence is one of the best ways to solve the problem of low
power-up current.
By default, all hard drives will start spinning up when powered-on.
These hard drives can be configured so that drives will not spin-up
at the same time when the enclosure is powered-on. There are 3
methods for spinning-up the hard drive's motor: "Spin-up at power-
on," "Spin-up serially at random sequence" or "Spin-up by SCSI
command." Please refer to the hard drive's documentation for
instructions on configuring the hard drive using the "Spin-up by
SCSI Command." The procedure for each brand/model of hard
drive may vary.
Configure all hard drives (usually by switching jumpers on hard
disks). Choose "SCSI Motor Spin-Up," then press [ENTER].
Choose Yes in the dialog box that follows to confirm the setting.
