1.1 Disk Array
A disk array or Redundant Array of Independent Disks (RAID) is a system that can improve
reliability compared to a single hard disk, by using a disk controller and multiple hard disks. Access
to each hard disk is controlled by the disk controller, but different control methods are used
depending on the RAID level settings. It is also possible to give the disk redundancy so that the
system can be operated continuously without losing data even when one hard disk fails.
1.2 RAID Level
Although there are several types of RAID level, the onboard SCSI array controller for this server only
supports RAID1. The number of available hard disks, available capacity and applicability of
redundancy are shown in the table below.
Regardless of the applicability of redundancy, data backup should be performed as
frequently as possible just in case.
For more details of RAID levels, refer to "A RAID Level" (pg.54).
RAID level Number of hard disks Available capacity Redundancy
RAID1 2 Capacity of 1 hard disk Applied

Chapter 1 Features (Product Overview/Note) 9
1.3 Logical Drive
Logical Drive
A logical drive is a logical hard disk space consisting of multiple hard disk drives. It is recognized in
the same manner as a single hard disk by the OS.
In the following figure, a RAID1 disk array is created using 2 hard disks.
It is recognized by the OS as if a single hard disk is connected.
In case of RAID1, the same data is written redundantly to 2 hard disks.
Use hard disks of the same capacity and speed for Disks 1 and 2.
Logical drive has 3 types of status as follows:
• Online
Indicates that the logical drive is operating properly.
• Critical
Indicates that the logical drive is operating without redundancy due to a failure of 1 hard disk. In
this case, replace the failed hard disk as immediately as possible and perform the procedure to
recover the status to "Online" (rebuild). For more details, refer to "1.4 Rebuilding/Initializing a
Logical Drive" (pg.10).
• Offline
Indicates that the logical drive is not operating. This status occurs when 2 hard disks that compose
the logical drive fail. In this case, data in the logical drive will be lost.
In the case shown in the figure above, if Disk 1 fails for instance, the logical drive status becomes
"Critical".
For the onboard SCSI array controller for this server, only one logical drive is created.
Multiple logical drives cannot be created.
Logical drive 0
Disk 1 Disk 2

10
1.4 Rebuilding/Initializing a Logical Drive
In case of RAID1 logical drives, the same data is always written to 2 hard disks. When 1 hard disk
fails, the logical drive continues to operate in "Critical" status (status without redundancy) with the
other hard disk. Rebuild is the operation to recover data redundancy by copying data from a hard disk
that is running normally after replacing a failed hard disk with a new disk. The logical drive in
"Critical" status is recovered to "Online" status by performing the rebuild.
If the status of the logical drive becomes "Critical," perform a rebuild immediately to recover the
status to "Online." If the other hard disk also fails while the logical drive is in "Critical" status, it
becomes "Offline" and data in the drive will be lost.
For how to replace hard disks, refer to "5.1 Replacing a Hard Disk" (pg.50).
Initializing a Logical Drive
Immediately after creating a logical drive, data in 2 hard disks may not be the same. It is therefore
necessary to initialize the logical drive so that the data in 2 hard disks becomes identical.
The onboard SCSI array controller for this server performs a rebuild process automatically after
creating a logical drive to initialize it.
If the server is reset or turned off before completion of a rebuild process, the process is
stopped. At the next restart, the rebuild process resumes from the block where the process
stopped.
During rebuild operations, the access LED of the hard disks that compose the target logical
drive will light up. Also, the Fault LEDs of the hard disks will blink.
Time Required to Complete Rebuild
Without normal I/O access, the time required for initialization is about 6.5 hours for 73GB, about 13
hours for 147GB, and about 26 hours for 300GB, excluding power-off time.
It may take more time if initialization is executed simultaneously with normal I/O access. The time
required may differ depending on the configuration and hard disk type.
If the initialization is not completed within the specified time (about 13 hours for 73GB, about 26
hours for 147GB, about 52 hours for 300GB), please contact the maintenance person or system
administrator.
Rebuild is performed in parallel with normal I/O access operations as a background
task. Before completion of the rebuild process, I/O processing performance may be
less sufficient compared to the logical drives that have been rebuilt.
In normal operations, RAID1 logical drives maintain redundancy. Immediately after
creating the array or replacing a failed hard disk, however, they remain without
redundancy until the completion of the rebuild process.

Chapter 1 Features (Product Overview/Note) 11
1.5 Media Verification
Media Verification is a function to detect/correct media errors of hard disks in advance. For the
onboard SCSI controller for this server, media verification is always performed when the logical
drive is Online.
If the hard disk other than the failed disk has a media error at the time of rebuild, data cannot be
restored by performing the rebuild. Media verification reduces the possibility of data loss during a
rebuild by correcting media errors in advance.

2.2 Other Points to Note
When connecting a hard disk that was previously used in the disk array configuration
to a general SCSI adapter, perform a low level format on the hard disk connected to
the SCSI adapter in advance.
While the server is turned on, do not remove any hard disks except for when
replacing a failed hard disk. (Only the hard disks in "Dead" state can be removed
while the server is on.)
When turning on the server shortly after turning off, leave for 10 seconds or more
before turning back on.
When creating a disk array using the onboard SCSI array controller for this server, do
not use hard disks of different capacity or speed.
Because hard disks previously used in another system may include unnecessary
partition information or array configuration information, unexpected problems may
occur in the data when reused. If connecting such hard disks to this server, perform a
low level format of the disks on the other system prior to connection.
