There is only one way to expand a CMS minidisk: 1. Create new minidisk that is larger than the old one 2. CMS FORMAT the new disk (without the RECOMP option!) 3. Copy the CMS files from the old disk to the new disk 4 . Delete the old minidisk 5. Rename the new minidisk to the old one. How you do those things can vary, but they all must be done. You cannot just add cylinders to an existing minidisk. DEDICATED dasd volumes can be dynamically resized via the storage controller admin functions, but CMS won't recognize or use the additional space.
