Whether OceanStor T Series RAID groups can be expanded

1. On OceanStor T Series V100R005 storage systems, you can add disks to the original RAID group online.
2. The traditional capacity expansion is implemented by creating more RAID groups. In this case, the complexity of managing storage resources increases when capacity expansion becomes frequent.
The dynamic RAID group expansion is to add new disks to the target RAID group, and instruct the storage device to incorporate the capacity of those disks arranged in a unified stripe depth with the LUNs in the RAID group. This method can increase the storage capacity without changing the number and configuration of RAID groups.
