Installing internal drives

If you add different types of drives, your system can read multiple types of media
and store more data. Several types of drives are available, such as:
v Diskette
v Hard disk
v CD-ROM
v Tape, including digital linear tape (DLT), super digital linear tape (SDLT), and
Note: The server supports both internal and external tape drives.
Your server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate your system while a hard disk drive is removed or installed. These drives
are known as hot-swap drives.
Each hot-swap drive has two indicator lights (see the User's Guide on the xSeries
Documentation CD). If the amber hard disk drive status light for a drive is lit
continuously, that individual drive is faulty and requires replacement. When the hard
disk drive status light indicates a drive fault, you can replace a hot-swap drive
without turning off the server.
Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive
tray. The drive must have a single connector attachment (SCA) connector.
Hot-swap-drive trays come with hot-swap drives.
