VNX 5800 - expanding storage pool issue.

Hi

I am trying to expand a Storage Pool on a EMC VNX 5800 array. The existing Pool has 99 disks with a mixture of Flash, SAS and NL-SAS.

When I try to expand it (using Unisphere) it will not allow me to expand by adding the disk below:
•      5 Flash   (RAID 4+1)
•      15 SAS (RAID 4+1)
•      NL –SAS  (RAID 6+2)

Is there any limitations on expanding Storage Pools with this version of VNX?

Many Thanks

•      5 Flash   (RAID 4+1)  - RAID-5
•      15 SAS (RAID 4+1)     - RAID-5
•      NL –SAS  (RAID 6+2)  - RAID-6

Not sure what EMC best-practice is but RAID-5 is not normally recommended for Business use anymore due to the extended rebuild times and the subsequent risk of a second disk failing before the rebuild completes - if this happens data is toast.
