I have read in the DOT 8.0 7-Mode admin guide that the root volume is installed/created at the factory before shipping.
This is somewhat confusing for me as how does the factory know how I want my disk space utilised?
I size a FAS2050 with 17 x 450GB SAS disks and I intend the configuration to look as follows to ensure I get the required usable capacity:
1 x Spare
1 x Default raid group size of 14 x data and 2 x parity
As this is a small system I would want the root volume to be created within a single aggregate which will be used for all volumes.
Will the factory create a 3 disk aggregate for the root vol and leave me with only 13 disk on which to create my single aggregate (11 data disk) or will they create a single aggregate with all disks and place the root vol here..??.!!?? – Also, how do they know I only want 1 spare disk..?
Am I missing something here, this can’t be correct? – Maybe I could understand this with larger systems and many disks but not small configurations..
Solved! SEE THE SOLUTION

Also, bear in mind that the aggregate containing the root volume must be a 32 bit aggregate. If you want a 64 bit aggregate, you'll have to create a new aggregate in addition to the one that contains the root volume.

So if you buy a 2xxx with only a few disks in or you buy a 31xx with lots of disk the factory will create a 3 disk 32-bit aggregate for the root volume – On the 2xxx I can add disks to the aggregate containing the root volume so I end up with one large 32-bit aggregate – With the 31xx and 2040 I can extend the aggregate containing the root volume for a larger 32-bit aggregate or leave the 32-bit 3 disk aggregate for the root volume and create a new 64-bit aggregate with remaining disks???

Yes, this is how it looks currently.
Common sense tells me at some point in a future root volume will become 64-bit, so the need for 32-bit 'root aggregate' will disappear (hopefully).
