If you have installed DFSMS, you can enlarge a minidisk with extra space added at the end of the minidisk: - verify you have DFSMS COPY: look for DFSMS MODULE on DGTOWNER 195 (DFSMS is a free feature of z/VM, but it is not pre-installed) - update the size of the minidisk in the CP directory - run DIRMAP to check you didn't create overlaps - LINK * 191 1191 MW - DFSMS COPY A 1191 - ACCESS 1191 Z - FORMAT 1191 Z (RECOMP - CP DETACH 191 - CP DEFINE 1191 191 - ACCESS 191 A It seems scary as it involves a MW LINK , but we tested this and used it several times when we where short of disk space and large minidisks had to be expanded. Note: DFSMS COPY is much faster than a FORMAT plus COPYFILE * * fm1 = = fm2 (OLDDATA; DATAMOVE will use DFMS COPY when it is available.
