10.2 Setup
10.2.1 Overview of Setup
The RAID controller of this equipment lets a device recognize two HDDs as one HDD.
In addition, the handling of RAID1 reaches only with an RAID controller.
Therefore, BIOS, the OS, the device driver to control an RAID controller are unnecessary.
Because it is recognized as normal SATA HDD, as for the equipment,
the installation of software for RAID controller is unnecessary at the time of setup.
10.2.2 Newly setting up RAID1
When RAID 1 is newly configured, RAID 1 configuration information
corresponding to only one equipment being used is recorded on the HDD.
The HDD with configuration information recorded can not be used with other
equipment, so users who use multiple equipment, should be careful to handle
and store HDDs to not to mix.
If HDDs are mixed, the RAID 1 configuration information may be inconsistent,
the equipment may not operate normally, or the data in the HDD 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 new RAID1 system on the Equipment, follow the procedure below.
This procedure is not necessary when you initially use the Equipment because a RAID1
system is factory-set.
1. Prepare two new HDDs.
2. Shut down the OS, disconnect the power cord plug from the outlet, and wait at least
one minute. Then, mount new HDDs in drive bay 1 and drive bay 2, referring to
Subsection 6.3.6, "Installing and removing an HDD" for details.
3. Turn on the Equipment by connecting the power cord plug to the outlet and pressing
the Power switch. The RAID controller automatically detects mounting of the new
HDDs and writes the RAID1 configuration information to both of these HDDs.
4. Install the OS using the Recovery DVD. (Refer to "CHAPTER7 RESTORING THE
FACTORY-SHIPPED CONDITION USING A RECOVERY DVD".)
