That's an indication of the space required for DFSMS's CONTROL file if you install in into SFS (the other choice is minidisks, which you appear to be using from prior posts).
In short, that says that the DFSMS CONTROL file would need 300 4k disk blocks of SFS space, and would be placed in the VMSYS "filepool", and the "DFSMS.CONTROL" filespace. If you're note familiar with SFS, it's easier to manage products in SFS when they run out of disk space (just increase their block "limit") compared to increasing a minidisk size. But SFS is (IMHO) very, **VERY** complicated to administer the first time something doesn't work. For example, the first time a filepool needs more disk space added, or when you're trying to perform backups or restores, or even what would seem to be a simple task like GRANTing someone access to files. >From a die-hard VM'er since 1978, my advice would be to stick with minidisks until you have a chance to experiment with SFS. It's a steep learning curve to get to reach the shining light at the top.
