Note
Because the server has a RAID controller, you
must reconfigure the disk arrays after installing
hard disk drives. Record the configuration
information.
Replacing a drive in a hot-swap bay
Note
You do not have to turn off the server to remove a
drive from the hot-swap bays.
Attention
Before you remove from a hot-swap bay a hard disk
drive that is not defective, back up all important data.
Before you attempt to remove a defective drive,
thoroughly review the information that appears on the
server screen to determine the location of the failed
drive. “ServeRAID menus, screens, and drive states”
on page 83 explains the status codes that the server
uses to indicate a defective drive. Also, if the amber
Hard Disk Status light for a drive is lit continuously,
that individual drive is faulty and needs to be replaced.
If you remove a hard disk drive that is not defective
from an array that already has a defective hard disk
drive, all data in the array will be lost. This situation is
especially relevant if you assigned RAID level 1 or 5
to the logical drives in the disk array. However, the
RAID controller can rebuild the data that you need,
provided that certain conditions are met. See
“Replacing a faulty drive” on page 129 for further
details.
Before you begin:
Ÿ
Read “Safety information” on page 308.
Ÿ
Read the documentation that comes with the
drive.
Ÿ
Reviewed “ServeRAID Configuration program” on
page 74. for information about the ServeRAID
controller and disk-array configuration.
Ÿ
Prepare the drive for installation (see
“Preinstallation steps (all bays)” on page 200).
Refer to the following illustrations while you perform the
steps in this procedure.
