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.
