Hi,

You can expand the RAID group, but it needs to be ADAPT disk groups. Only ADAPT disk groups can be expanded in virtual pool mode. RAID 5 and RAID 6 disk groups cannot be expanded in virtual pool mode. 

- To expand the capacity of a virtual pool that contains existing RAID 5 or RAID 6 disk groups, the administrator must add sufficient disks to create a new disk group.
- Navigate to "RAID Groups" > "Storage" > "Storage Configuration" > "Storage Pools" > "RAID Groups" Tab.
- Right-click the desired RAID Group LUN to be expanded.
- Select "Expand."
- Select the desired LUN Expansion Type: Striping or Concatenation.
- Select the desired Component LUN(s) you want to add to the Base LUN.
- Select the desired LUN User Capacity.
- Select the desired LUN settings, such as MetaLUN Name.
- Follow the on-screen instructions to complete the expansion process.

Hello Joey,

is it possible to convert to an ADAPT disk group without downtime and data loss?

Hi,

As I know no, I say this inference because ADAPT disk groups use a different data layout compared to traditional RAID types. This means the data needs to be rewritten to the new format, which is a process that requires the disk group to be offline. White Paper: Dell PowerVault ME5 ADAPT Software (https://dell.to/3vWkK4K)
