Backing up data
Always create backup copies of important data on a hard disk to auxiliary storage. If the hard
disk fails, all data stored on the disk will be lost.
Refer to [Chapter 1: Handling the System Equipment and Peripheral Equipment].
Disk array

You must not change a disk array during system operations. If you do, all data will be lost
from those disks due to change in the disk array.
Refer to [Chapter 5: Building Disk Arrays].

When enabling the write cache of the disk array, connect the system equipment to UPS.
When you use the equipment without connecting to the UPS, data can disappear and be
corrupted.
Refer to [Chapter 5: Virtual Drives; Building Disk Arrays for RAID 0, 1, 5, and 6; Building
Disk Arrays for RAID 10; Changing the Write Policy for Disk Arrays].

When a disk array is deleted, all data in those hard disks including the disk array
information will be lost. Backup your required data before deleting a disk array.
Refer to [Chapter 5: Deleting Disk Arrays].
