Expanding a Static Volume by Adding Disks to a RAID Group
The total storage capacity of a static volume can be expanded by adding one or more additional disks to a
RAID group in the static volume. This extra capacity can be added online, without any interruption to data
access.
Important
• Adding disks to a RAID 1 group changes the RAID type of the group to RAID 5.
• To expand a RAID 50 or RAID 60 group, every sub-group must be expanded with the
same number of disks.
1. Verify the following:
• The storage pool you want to expand contains at least one RAID group of type: RAID 1, RAID 5,
RAID 6, RAID 50 or RAID 60.
• The NAS contains one or more free disks. Each free disk must be the same type as the other disks
in the RAID group (either HDD or SSD), and have a capacity that is equal to or greater than the
smallest disk in the group.
• The status of the RAID group that you want to expand is Ready .
