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

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.
