In Pool B it looks like there are two Virtual DIsk Group. Out of them one is used as Read Cache so that one created with SSD drive. What about other VDG ?
Now in Pool A what type of drive you want to use to create new Virtual Disk Group ? is it SAS drives or SSD ?
Can you please provide me the below output,
# show disks
# show pools
# show disk-groups
You cannot create virtual disk groups that contain SSDs without the Performance tier license. You can have SSDs in a fault tolerant Disk Group as a Performance Tier or as a non-fault tolerant (up to 2 disks) Disk Group as Read Cache. But neither pool can have both a Performance Tier and a Read Cache. For example, pool A can have a Performance Tier and pool B can have a Read Cache.
Note any license required for the System level and it's not specific to any Pool.
You must have tried to create VDG and got error because there is bydefault two Pools exist. If you are unable to see another Pool that's because there is no VDG exist for that Pool.
Hope this helps!
