All data from the array is lost, regardless of the
RAID levels assigned to the logical drives.
To replace a faulty drive:
1. Before you remove or replace a drive that you
suspect to be defective, verify that the drive is
defective. To do this:
a. Check the drive for damage.
b. Verify that the drive is positioned correctly. If the
drive is not installed correctly, reposition the
drive.
c. Check the lights on the drive tray. (See the
following information for a description of the
lights.) Verify that you can remove the drive
safely.
The lights on the hot-swap drive tray provide
drive status information, as follows:
Ÿ
Hard Disk Activity Light: When this green
light is flashing, it indicates that the server
is accessing the drive.
Ÿ
Hard Disk Status Light: When this amber
light is lit continuously, it indicates that the
drive has failed. When the light flashes
slowly (one flash per second), it indicates
that the hard disk drive is part of a disk
array and is being rebuilt. When the light
flashes rapidly (three flashes per second), it
indicates that the controller is identifying the
drive. The drive
should not be replaced if
this light is blinking; the drive has just been
replaced and the disk array is being rebuilt.
2. Physically replace the defective drive or use an
existing RDY drive that has a capacity equal to or
greater than the drive that you are replacing as a
hot-spare replacement drive.
Attention
Removing the wrong hard disk drive might cause
loss of all data in the array.
.
a. To physically replace the defective hard disk
drive, follow the instructions in “Internal drive
installation” on page 197 and “Installing a drive
in a hot-swap bay” on page 203; then, follow the
instructions in “Understanding the drive rebuild
process” on page 131.
b. To rebuild the defunct drive to an existing RDY
drive, follow the instructions in “Understanding
the drive rebuild process” on page 131.
