8.2.1 Setup overview
The RAID controller installed in this equipment lets the equipment recognize the two HDDs
as one HDD. The RAID controller performs RAID1 processing. Therefore, the BIOS to
control the RAID controller from the equipment or a device controller to control the RAID
controller from the OS is not necessary. Since the equipment recognizes the HDDs as
normal SATA HDDs, you don't need any special software to set up RAID1.
8.2.2 Building a RAID1 system newly
When a RAID1 system is newly built, the RAID1 configuration information is
recorded on the HDDs. An HDD with configuration information recorded cannot
be used in any other equipment. If you are using more than one HDD, be
careful in handing and storing them so that you do not mistake one from
another. If HDDs are mixed up, a RAID1 configuration information mismatch
occurs. The equipment may not operate properly, and the data on the HDDs
may be lost.
When you build a RAID1 system from scratch, prepare two new HDDs selected
from the models specified and tested by HITACHI. Otherwise, the data stored
on the HDDs may be lost.
To build a RAID1 system, follow the procedure below.
Note that, when the product is shipped, a RAID1system has been already built, and the
following procedure is not necessary.
 Prepare two new HDDs.
 Shut down the OS. Turn off the main power to the equipment, and wait for at least one
minute. And then mount the HDDs on drive bays 1 and 2. (See" 5.3.5 Installing and
removing an HDD".)
 Plug the power cable to the outlet to turn the equipment on. The RAID controller
automatically recognizes that HDDs are installed and writes RAID1 configuration
information to both HDDs.
 Install the OS using a recovery DVD (refer to the HF-BX1000/1200 SETUP GUIDE).
