14. Install additional internal hot-swap hard disk drives in the 3-Pack Ultra320
Hot-Swap Expansion option (see “Installing a hot-swap hard disk drive” on
page 39).
Note: The 3-Pack SCSI backplane sets the SCSI IDs for these hot-swap hard
disk drives. See “SCSI IDs” on page 74 for additional information.
15. If you have other options to install or remove, do so now; otherwise, go to
“Installing the server bezel and left-side cover (tower model)” on page 62 or
“Installing the server bezel and top cover (rack configuration)” on page 65.
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
DVD-ROM
v
Tape, including digital linear tape (DLT), super digital linear tape (SDLT), and
linear tape-open (LTO)
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 LEDs (see the User’s Guide on the IBM
xSeries Documentation CD). If the amber hard disk status LED for a drive is lit
continuously, that individual drive is faulty and requires replacement. When the hard
disk drive status LED 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.
