P2000 G3 iSCSI MSA Question

Hey All,

I need to perform a volume copy. I think what I need to do is to expand the existing Vdisk, then create a new volume using the expanded space.

Here is my problem: The current Vdisk is using 600 GB HHDs and the volume I need to copy is 4195.5 GB (4.2TB). 

I have two 600 GB HDDs (1.2TB) remaining. I also have four spare 300 GB HDDs and ten 1.8TB HDDs. Can I add these to the existing Vdisk for expansion or does the Vdisk need to be homogenous?

Is there a firmware issue to be concerned with?

Thanks,

Vint
