HARDWARE INSTALLATION

2.3.1 Hot-plug Drive Replacement

The RAID controller supports the ability of performing a hot-swap

drive replacement without powering down the system. A disk can

be disconnected, removed, or replaced with a different disk with-

out taking the system off-line. The RAID rebuilding will be pro-

cessed automatically in the background. When a disk is hot swap,

the RAID controller may no longer be fault tolerant. Fault toler-

ance will be lost until the hot swap drive is subsequently replaced

and the rebuild operation is completed.

2.3.2 Recognizing a Drive Failure

A drive failure can be identied in one of the following ways:

1. An error status message lists failed drives in the event log.

2. A fault LED illuminates on the front of RAID subsystem if failed

drives are inside.

2.3.3 Replacing a Failed Drive

With RAID subsystem drive tray, you can replace a defective

physical drive while your computer is still operating. When a new

drive has been installed, data reconstruction will be automatically

started to rebuild the contents of the disk drive.

Note:

The capacity of the replacement drives must be at least

as large as the capacity of the other drives in the raid set.

Drives of insufcient capacity will be failed immediately by

the RAID adapter without starting the Automatic Data Re-

build.
