LUN Unbind Error "Contained Within a Storage Group"

This is a NS20 device, but not in production, ok to erase raid. Current Configuration is

Disk Group ID: 0 r5 Disks: 0_0_0,0_0_1,0_0_2,0_0_3,0_0_4
Disk Group ID: 8 r5 Disks: 0_0_6,0_0_7,0_0_8,0_0_9,0_0_10
Disk Group ID: 201 Unbound Disks: 0_0_11
Disk Group ID: 202 Unbound Disks: 0_0_12
Disk Group ID: 203 Unbound Disks: 0_0_13
Disk Group ID: 204 Unbound Disks: 0_0_14

My objective is to remove the raid group 8 and recreate the RAID as ATA_RAID5_4+1_HS_8+1

I am trying to unbind the LUN using Navisphere Manager.
Local Domain->CX310->Storage Groups->Celerra_emcnas_i0->LUNS->Right Click on LUN 19->Unbind LUN
I get the following error:
"Contained Within a Storage Group"

What are the steps that I need to follow?

Thanks
