I'm getting no where trying to get this server up and running because I can't find a way to allocate the RAID groups to the locally installed SSD disks.
The server has the following disks in the following order:
| Disk | Size (GB) |
| 1 | 960 |
| 2 | 960 |
| 3 | 960 |
| 4 | 960 |
| 5 | 960 |
| 6 | 960 |
| 7 | 960 |
| 8 | 960 |
| 9 | 300 |
| 10 | 300 |
| 11 | 240 |
| 12 | 240 |
| 13 | 240 |
| 14 | 240 |
| 15 | 960 |
| 16 | 960 |
| 17 | 960 |
| 18 | 960 |
I'd like to configure the disks in the following fashion:
| Disk | Size (GB) | Desired RAID Group |
| 1 | 960 | RAID10- DDB |
| 2 | 960 | RAID10- DDB |
| 3 | 960 | RAID10- DDB |
| 4 | 960 | RAID10- DDB |
| 5 | 960 | RAID10- DDB |
| 6 | 960 | RAID10- DDB |
| 7 | 960 | RAID5- Index |
| 8 | 960 | RAID5- Index |
| 9 | 300 | RAID1- Boot |
| 10 | 300 | RAID1- Boot |
| 11 | 240 | NA |
| 12 | 240 | NA |
| 13 | 240 | NA |
| 14 | 240 | NA |
| 15 | 960 | RAID5- Index |
| 16 | 960 | RAID5- Index |
| 17 | 960 | SPARE |
| 18 | 960 | SPARE |
When I apply my Service Profile (SP) to the physical server, I get this error:
Failure Reason: There are not enough resources overall
Insufficient disks for the specified raid level
LUN Resource Selection Logs for Service Profile ecmsp09, LUN RAID5-INDX:
Order Description

I don't get it. The disk groups should only use up 12 disks while there are 18 disks in the server.
I then removed the RAID5 disk group from the storage profile, and tried again, and get this error:
Failure Reason: There are not enough resources overall
Insufficient disks for the specified raid level
LUN Resource Selection Logs for Service Profile ecmsp09, LUN RAID10-DDB:

| 3 | Cannot carve out of the existing disk groups. Trying to create a new disk group |

My disk groups look like this:
<lstorageDiskGroupConfigPolicy

dn="org-root/disk-group-config-STR-OS-2D-R1"

I won't post the RAID5 config unless it's required, but it's a 4x SSD disk RAID5 setup.
I then re-applied the Service Profile using just the "BOOT-R1" & "RAID10-DDB" disk groups and it looks like it would be successful, however it's using the wrong disks for the BOOT LUN:
Service Profile ecmsp09 (org-root/org-Dedicated/org-MedAgt/ls-ecmsp09) [Server: sys/rack-unit-8]

| 8 | Select normal disk in slot: 4 |

| 10 | Select normal disk in slot: 6 |
Is there a way to achieve the required result?
My last hope will be to go to the datacenter and re-arrange the disk order then modify the disk groups by setting them to "Disck Group Configuration (Manual)" and manually selecting the disk slots to use for each RAID group.
