8-10 System Upgrade
Replacing 3.5-inch Hard Disk Drive
Follow the procedure below to remove the failed hard disk. If the hard disk fails, it should be
replaced with new device with the server powered-on.
IMPORTANT: Make sure to read "Anti-static Measures" and "Preparing Your System for
Upgrade" before starting installing or removing options. You can replace disks during
continuous operation.
Replacing the Hard Disk Drive
1. Locate the failed hard disk.
When a hard disk fails, the DISK LED on the hard disk drive’s handle illuminates green,
while the DISK LED of the other mirrored disk illuminates amber.
The DISK Access LED of the disk whose DISK LED is amber also illuminates amber.
TIPS: Even if a hard disk fails, the DISK LEDs may not illuminate as described
above. See “How to Locate Failed Disks” in Chapter 3 to identify failed disks.
2. Referring to steps 1 and 2 in “Restoring Redundant Configuration Manually” (page 3-6),
disconnect the failed hard disk from RAID and then remove it.
No need to shutdown the OS.
3. Refer to the steps in "Installing the hard disk" to install a new hard disk.
TIPS: The hard disk to be installed for replacement must have the same specifications
as its mirroring hard disk.
4. Restore the redundant configuration (see Chapter 3).
