●Notes on Operations in RAID1 Configuration
When disks of the server are used in RAID1 redundancy configuration, the disk data is protected even if
a single hard disk unit has failed. However, if both hard disks have failed, the disk data will be
permanently lost. Also, if the user repeatedly powers on/off or repeatedly reboots while a single disk unit
has failed, data reliability may be lost.
If a disk failure is detected, replace the failed disk unit as soon as possible to safeguard customer data.
