The target name of virtual disk.
The clone schedule of virtual disk:
The health of virtual disk:
"Optimal"  the virtual disk is working well and there is

no failed disk in the RG.
"Degraded"  At least one disk from the RG of the Virtual

disk is failed or plugged out.
"Failed"  the RAID group disk of the VD has single or

multiple failed disks than its RAID level can recover from
data loss.
"Partially optimal"  the virtual disk has experienced

recoverable read errors. After passing parity check, the
health will become "Optimal".
Ratio (%) of initializing or rebuilding.
RAID level.
Number of LUN(s) that virtual disk is attached to.
The virtual disk size that is used for snapshot. The number
means "Used snapshot space" / "Total snapshot space".
The unit can be displayed in GB or MB.
Number of snapshot(s) that have been taken.
The RG name of the virtual disk
Create a virtual disk.
Extend the virtual disk capacity.
Execute parity check for the virtual disk. It supports RAID 3 / 5 /
6 / 30 / 50 / 60.
Regenerate parity:
"Yes"  Regenerate RAID parity and write.

"No"  Execute parity check only and find mismatches. It

will stop checking when mismatches count to 1 / 10 / 20
