6.
Check the hard disk drive status indicators to verify that the hard disk drives are
operating properly. (See “Server controls and indicators” on page 6 for the
location of the status indicators.)
• When the green light flashes rapidly (three flashes per second), the controller is identifying the drive.
Replacing a hard disk drive is done in the same manner as installing a new hard disk drive.
If the server has a Redundant Array of Independent Disks (ServeRAID) adapter installed, you can hot-swap drives. For more information about hot-swapping drives
refer to the documentation provided with the ServeRAID adapter, “Hot-swap disk
drives”, and to the notes under “Hard disk drives” on page 48.
Hot-swap disk drives
Your server can be configured with hardware to let you continue to operate your system while removing or installing hard disk drives (or hot-swapping). To do this you need a ServeRAID adapter, hard disk drive, and the hard disk drive tray.
• Each hard disk drive that you plan to install must have an accompanying hard disk drive tray.
• The drive must be a low-voltage differential drive (LVD), and have a single connector attached (SCA) connector.
• The hard disk drive bays connect to a SCSI backplane. This backplane is the printed circuit board behind the bay and is connected to the ServeRAID adapter.
• The backplane controls the SCSI IDs for the hard disk drives.
Preinstallation steps
Before you install a hard disk drive, review the following.
• Inspect the drive tray for any signs of damage.
• Ensure that the drive is installed properly in the tray.
• To maintain proper system cooling, do not operate the server for more than two minutes without either a drive or a filler panel installed in each bay.
• If your server has a ServeRAID adapter installed; refer to the documentation provided with the ServeRAID adapter for information about adding a drive.
•
• Check the instructions that come with the drive to see if you need to set any switches or jumpers on the drive.

Complete the following steps to install a hot-swap drive in a hot-swap drive bay:
Attention:
• To maintain proper system cooling, do not operate the server for more than two minutes without either a drive or a filler panel installed for each bay.
• When you handle electrostatic discharge sensitive devices (ESD), take precautions to avoid damage from static electricity. For details on handling these devices,
refer to “Handling electrostatic discharge-sensitive devices” on page 110.
1.
Remove the filler panel from one of the empty hot-swap bays by inserting your finger into the depression at the left side of the filler panel and pulling it away from the server.
2.
Install the hard disk drive in the hot-swap bay: a.
Ensure the tray handle is open (that is, perpendicular to the drive).
b. Align the rails on the drive assembly with the guide rails in the drive bay.
c.
Gently push the drive assembly into the bay until the drive connects to the backplane.
d. Push the tray handle toward the closed position until it locks the drive in place.
3.
Check the hard disk drive status indicators to verify that the hard disk drives are
operating properly. See “Server controls and indicators” on page 6 for the
location of the status indicators.)
• When a ServeRAID adapter is installed and:
— The amber light is on continuously, the drive had failed.
— The green light flashes slowly (one flash per second), the drive is being rebuilt.
— The green light flashes rapidly (three flashes per second), the controller is identifying the drive.
Replacing a drive in a hot-swap bay
You do not have to turn off the server to remove or install the hot-swap drives.
1.
Before you remove a hot-swap hard disk drive that is not defective, back up all important data.
Chapter 5. Installing options

2.
To avoid damage to a hard disk drive, do not remove the drive from the hot-swap bay until it has had time to spin down (approximately 30 seconds). Handle the drive carefully.
3.
Before you replace a hot-swap drive, make sure it is defective. If you partially or completely remove a good drive instead of a defective one, the server might lose valuable data.
This situation is especially relevant if the server has a ServeRAID adapter installed and you assigned ServeRAID level 0 or 1 to the logical drives in your disk array. The ServeRAID adapter can rebuild the data that you need, provided that certain conditions are met. Refer to the information provided with the
ServeRAID adapter for further details.
Refer to the following illustration while you perform the steps in this procedure.

Complete the following steps to replace a drive in a hot-swap bay:
1.
Before you begin, read the documentation that comes with your drive.
2.
Locate the defective drive (look for an amber Hard Disk Status light on the front of the drive).
3.
Remove the defective hard disk drive: a.
Move the handle on the drive to the open position (perpendicular to the drive) b. Pull the hot-swap drive assembly from the bay.
4.
Install the hard disk drive in the hot-swap bay: a.
Ensure the tray handle is open (that is, perpendicular to the drive).
b. Align the rails on the drive assembly with the guide rails in the drive bay.
c.
Gently push the drive assembly into the bay until the drive connects to the backplane.
d. Push the tray handle toward the closed position until it locks the drive in place.
5.
Check the hard disk drive status indicators to verify that the hard disk drive is
installed properly (see “Server controls and indicators” on page 6 for the location
of the status indicators).
• When a ServeRAID adapter is installed and:
— The amber light is on continuously, the drive has failed.
