HP 2040 expand pool with new disk group

I had a MSA 2040 with 7 disks. 6 disks for data and 1 disk for Global Spares. I created a pool A with 6-disks group, type was virtual pool and raid 0+1 .
Now, i buy 5 new disks, same information, same type, same size ...
I want to expand this 5 new disks to pool A(virtual pool).
It is work ? How can do this?
Thank you
