Since when is adding DASD so difficult?

[pam@xxxxxxxxxxxxx]

I could use some advice on the following conundrum:

We have a Model 720 on V4R4. All the bays in both the system unit and the
expansion unit are filled with 8 GB drives, giving us a total capacity of
about 300 GB. We need to add about 100 GB. I had thought the obvious solution
would be to add another expansion unit and add in some 17 GB drives.  Simple,
right?

I am told that the current technology for expansion, a PCI tower, requires
V4R5.
The next option is swapping 8 GB for 17 GB drives in place. This means a lot
of planning to cover the risks.
Another possibility would be to get a used SPD tower, which may need to be
discarded when we finally do upgrade our OS.

What's your feeling on these options? Do you have any other suggestions?
