CHAPTER 10 RAID1
10.1 What is the RAID1
This chapter describes how to manage the RAID1 feature.
Note that the HDD or SSD used by this equipment are hereinafter referred to as "drive".
Note that the RAID1 feature can be used only if it is configured with drive bay 1 and drive
bay 2.
The screen images used in this chapter are the ones for Windows® 10, but the displayed
content is basically the same for other OSs.
● Although this Equipment featuring RAID1 is more reliable than general systems, it is
still prone to the loss of data in the drives. Not only a machine failure but also an
unexpected power failure or an operation error may cause data to be lost for good.
To prevent such loss of data, implement scheduled data backup in daily operation.
Also, protect the power source from undesirable interruptions by such means as
UPS.
● This Equipment is evaluated based on the specific drive models authorized by the
Manufacturer. Replace only with specific drive models authorized by the
Manufacturer. Otherwise, the existing data in the drive may be lost. Also, always
observe the recommended replacement interval for drives (Refer to "APPENDIX
HANDLING REPLACEABLE COMPONENTS").
● Since each Equipment has its own RAID1 configuration information (e.g., serial
number), you cannot swap drives even between two units of this Equipment. Failure
to heed this instruction might result in unexpected operation because of a problem
such as inconsistent configuration information. If you own multiple units of this
Equipment, manage use and inventory of drives so that they are not inadvertently
mixed.
● Do not use a used drive as a replacement drive, regardless of the model. Failure to
heed this instruction might result in the equipment not operating normally or data in
the drive being lost due to inconsistent configuration information.
● Use a new drive (unused drive) or an initialized drive as a replacement drive .
● Maintenance of a RAID1 system requires a high level of expertise. Should any
mistakes be made during the work, the data stored on the drives may be lost.
● The drives in drive bay 1 and drive bay 2 must have the same capacity. Do not
install drives with different capacities.
