Re: How do I shrink NWS Storage Space?

So, exactly how do I do this? Do I have to wipe out the v7r1 partition and the NWSD and spaces and build a new hosted partition with v7r1 (with much smaller storage spaces allocated)?

I'd create an image catalog with an empty optical image, large enough to hold an entire backup of the machine. Maybe a bit larger. Then, RTVCLSRC of QMNSAVE (gets called with a save 21), and modify it so the image created before does not backup into itself. Compile and do a Save 21 into this image.

Shut down the LPAR. Do RMVNWSSTGL and DLTNWSSTG in the hosting LPAR. Create new, smaller *STG and attach with ADDNWSSTGL.

Any *IMGCLG I attach to a virtual optical drive on the hosting LPAR is available as OPT02 on secondary LPARs, while the hardware drive is OPT01. Do a D-Mode IPL from the image created earlier (can take up to 10 minutes until firmware decides to give up on OPT01 and checks OPT02), and do a full restore.

Clean up. Done.

I did *not* test that procedure! I strongly recommend to do a complete save with disconnected NWS (for also saving the client LPAR disk files), before beginning. I also strongly recommend to have copy of iVirtualization PDF at hand, because the descriptions about what to configure where for new LPARs (or, as here, new storage) is documented there for easy reading.
