Sorry, you are right, I only read the Post above.
Notice this:
- The Performance Auto Tiering License is not required in Linear Storage configurations not utilizing Virtual Storage Disk-Groups and Pools.
- Creating an SSD virtual disk group for both read and write capabilities requires a Performance Auto Tiering License.
Your existing Disks is a Type Linear Pool, I think you try to create a Virtual DG/Pool.
Maybe the new GUI doesn't offer Linear anymore.
Try to use CLI: add disk-group type linear disks 1.17-24 level r6 dg02
