Creating VV "Direct from PDs"

[nocode]

My company has an old E200 and upon looking at the capacity, we should have about 3-4 TB of raw data left however, all current CPG's are maxed out with Virtual Volumes and when I try to create a new CPG, it's not allocating any space to the CPG.

I fumbled around the VV section and was able to create about 1.3 TB VV from "Direct from PDs". I've been searching around my PDF's and the net, but nothing is telling me what exactly PDs (i'm guessing physical disks) and what the purpose of PDs are. Could someone elaborate? I don't want to use this space if it's needed for something. I'm just curious why I can't assign this to a CPG

Thanks,

It's exactly what it says:

Create Virtual Volumes from Physical Disks

It's not assignable to a CPG because of the policies defined in CPG's, there's always a little bit of overhead in a 3Par which is not assignable.

are you trying to create a new CPG or add space to an existing one?
the overhead is pretty low on 3PAR, mainly the admin volume and SA space

What error are you getting when you try to create a new CPG? What options are you using to create the CPGs?

CPGs aren't like traditional disk arrays that you commit freespace to first, then use it for volumes. CPGs start at a minimum size (32g on my system) and will grow as needed to accommodate the volumes within, assuming you have freespace on the PDs to accommodate the growth.
