Scenario:
1. Windows Server 2012 R2 blueprint configured with 60GB Disk 0, 50GB Disk 1.
2. Creating new request from said blueprint, modifying 50GB Disk 1 Storage in request to blueprint storage maximum (200GB)
3. Finished VM does not have a 200 GB Disk 1, rather it still has a 50 GB Disk 1 (as in the blueprint).
Testing:
1. Removed disk 1 from blueprint and re-added disk during request, works with manually specified size, etc.
2. Changed label for Disk 1 in request, label changes in resulting VM. (So blueprint label can be overriden in the request)
3. Capacity does not appear to be overridden despite being overridden in request.
4. No custom properties in storage specified.
5. Additional disks i.e. Disk 2, Disk 3 can be added in request and properly provisioned in final VM. Changing Disk 1 capacity in request still has no effect.
Conclusion: The capacity for Disks specified in the blueprint cannot be overridden, although their labels can be overridden. Any ideas?
