Re: Need to "Back Out" installed drives
If they are not included in the RGs then you will not be able to use them in the array. You can NOT treat them as normal JBOD disks.
What exactly were you hoping to accomplish with these drives?

No choice of removing the disk from RG, once it is added.

Re: Need to "Back Out" installed drives
With the VA7400 the disks in the odd-numbered slots are all in RG 1 and the disks in the even numbered slots are in RG 2.
So no matter how you add the drives, in order for them to be usable in the VA they must be included, whether automatically or manually doesn't matter, and they will then be part of the RG appropriate for the slot they are plugged into.

Re: Need to "Back Out" installed drives
No you are NOT limited to only 2 LUNs, far from it. But you are limited in how you create the LUNs. A LUN can be created in either RG1 or RG2. Not both. An you can not specify a granularity smaller than the RG.

Re: Need to "Back Out" installed drives
Despite my original instructions, they set me up with 3 x 36 GB and 1 x 18 GB drives per RG. From discussions with other HP engineers, I should not have gotten the (3*33.37+16.68)/2 = 58.39GB that would normally have been expected from a RAID 1+0 configuratiion. The mismatch of the one 18 GB drive should have given me something less. Apparently my vendor was able to "force" the VA to give me all expected space. Well they didn't tell me.
So when I added my 73 GB drives on each RG, I expected similar behavior, and of course I was disappointed. I only got an additional 16 GB instead of the expected 33. Removing the 18 GB and replacing it with a 36 GB in each RG helped get me the additional disk space I was missing.
My original request was just asking for the feasibility of immediately removing the 73 GB drives to get back to my original configuration so I can re-analyze me situation.
Thanks for all of your attempts to try to understand what I needed.
