Installing a device driver

A device driver is software that lets the server communicate with a particular
SCSI device.

Note: If you have set up your server and connected additional devices, but not
yet turned the server on, return to the section “Plugging In the Server” in
Chapter 1 before installing a device driver.

To install a driver:

Start up your server, if necessary, and drag the driver icon to the System Folder icon on

your startup disk.

Any drivers needed for a SCSI device are usually on a floppy disk that comes
with the device. (If no drivers come with the device, then it doesn’t need any.)
You may have to restart your server to activate the driver.

Do you need to initialize a hard disk?

You need to initialize a hard disk only in the following cases:

m You’re using specialized disk array management software, such as RAID

(redundant array of independent disks). See the documentation that
accompanied the disk array management software for instructions.

m The disk is new and uninitialized. Your internal hard disk and most external

hard disks are initialized at the factory and do not have to be initialized
again. If you are adding a new non-Apple hard disk to your server, check
your owner’s manual to see if it needs to be initialized.

m You’ve experienced repeated errors using this disk. If problems persist after

you reinitialize the disk, the disk is in need of servicing.

m The disk has been formatted for use with a non-Apple operating system.
