We have a bunch of different blueprints for use by different business groups. All of them are basically the same as far as the template used, initial storage size, etc. Today I was going to provision a VM with a different disk size, so I went into a particular blueprint, selected the "Storage" tab and clicked the Edit icon to change the size from the initial 8GB to 20GB, but it was greyed-out (it did allow me to change the storage type, though). I went into another blueprint and it would allow me change the size. I then went through all of the blueprints and most would not allow me to change the initial size to provision, but some would. I've gone over all the blueprints, reservations, etc., and cannot see any property or check mark anywhere that would turn this feature on or off, so I'm stumped at the moment. Anyone have an idea how this feature is turned on/off? Thanks.
Here is a screen shot of how it looks for the blueprints that DO allow me to change the initial storage size when provisioning:
... and here is one for a blueprint that does NOT allow me to change the initial storage size when provisioning:
