6.5 Disk Roaming
Physical disks can be re-sequenced in the same system or move all physical disks from
system-1 to system-2. This is called disk roaming. System can execute disk roaming
online. Please follow these steps:
1. Select “/ Volume configuration / RAID group”.
2. Check the gray button next to the RG number; click “Deactivate”.
3. Move all PDs related to the RG to another system.
4. In the web GUI of the other system, check the gray button next to the RG
number; click “Activate”.
5. Done.
Disk roaming has some constraints as described in the following:
1. Check the firmware of two systems first. It is better that both systems have
the same firmware version or newer.
2. All physical disks of related RG should be moved from system-1 to system-2
together. The configuration of both RG and VD will be kept but LUN
configuration will be cleared in order to avoid conflict with system-2.
6.6 VD Clone
The user can use VD clone function to backup data from source VD to target VD, set up
backup schedule, and deploy the clone rules.
The procedures of VD clone are on the following:
1. Copy all data from source VD to target VD at the beginning (full copy).
2. Use Snapshot technology to perform the incremental copy afterwards. Please be fully
aware that the incremental copy needs to use snapshot to compare the data
difference. Therefore, the enough snapshot space for VD clone is very important.
The following contents will take an example of a RAID 5 virtual disk (SourceVD_Raid5)
clone to RAID 6 virtual disk (TargetVD_Raid6).
 Start VD clone
1. Create a RAID group (RG) in advance.
