2.3.3 Expand RAID Set
This function allows the user to directly expand the capacity of a RAID set currently in use without having
to delete the current RAID set before rebuilding.
Notes : 1. The newly added capacity must have a volume set up before it can be used. This can be performed
through “Volume Set Functions”.
2. Once a capacity expansion is in progress the process can’t be paused.
3.Duringacapacityexpansion,ifoneoftheHDDisdamagedandthereisaHotSparedened,oncethe
capacity expansion is complete the system will automatically rebuild the data.
4. If the original storage already contains data, please backup the data to another machine’s storage space
before proceeding with the expansion to avoid losing your data.

2.3.8 Rescue RAID Set
The “RESCUE” function can recover the missing RAID set information.
2.4 Volume Setup
Once a RAID set has been set up, all of the storage capacity on the physical disks will be treated as one
single storage space. This is not normally recognized by operating systems so the storage space must be
