Removal and Replacement Procedures

Drive Failure Scenarios

IMPORTANT: This section applies only to ATA models of the ProLiant ML310 server.
When a drive fails:
•
Insight Manager notifies you of the drive failure.
•
If applicable to the operating system, the RAID status icon changes from green to red to
indicate that there is a problem. The icon is represented as a round figure wearing
sunglasses and is located in the tray bar at the lower right of the screen.
•
Some operating systems will also write to the console and/or a log file.
IMPORTANT: Some operating systems do not display the RAID status icon or the icon may be
displayed differently.
The following sections provide instructions for rebuilding an array when a drive fails.

RAID 0 Configurations

A drive failure in a RAID 0 configuration causes data loss across the entire array. To recover
from a drive failure, the array must be rebuilt from scratch. To rebuild the array:
1. Determine the failed drive by viewing the information provided at Power-On Self Test
(POST) and in the Integrated ATA RAID Configuration Utility by pressing the F8 key.
2. Power down the server, and then replace the failed drive.
3. Reboot the server and configure the array using the menu options in the Integrated ATA
RAID Configuration Utility by pressing the F8 key.
Refer to "Integrated ATA RAID Configuration Utility" in this chapter for information on the
utility menu options.

RAID 1 Configurations

NOTE: This configuration is the only one where a spare pool configuration will have any value. A spare
will provide a means by which a failed drive in a RAID 1 configuration may be rebuilt online.
In a RAID 1 configuration, there are two possible scenarios if a hard drive fails:
•
If an online spare is configured:
— The auto-rebuild process occurs without user intervention, removing the failed drive
— Reconfigure the online spare by doing the following:
a. Power down the server, and then replace the failed drive.
b. Run the Integrated ATA RAID Configuration Utility by pressing the F8 key, and
2-20
from the array and adding the spare to the array.
then configure the drive as a spare.
