and settings.
Create manually: It is to create RAID manually. Please select RAID type first and then follow the
prompts to set HDD amount. Click Create Manually button, system pops up dialogue box to warning
you it is going to clear all data. Click OK button to complete the operation.
Create RAID: Click it to automatically create RAID5.
For create RAID function, you can select the physical HDD that does not included in the RAID group or
the created disk array to create a RAID5. You can refer to the following situations:
There is no RAID, no hotspare disk: System directly creates the RAID5 and creates one hotspare
disk at the same time.
There is no RAID, but there is a hotspare disk: System creates the RAID5 only. It uses previous
hotspare disk.
There is RAID: System cancel the previous RAID setup and then create the new RAID5. System
creates the hotspare disk if there is no one. System uses previous hotspare disk if there is hotspare
disk available.
The background will format the virtual disk.
