This is the additional message DFSMShsm writes when an LSPACE is done for track-managed space for the Extended Addressable Volume (EAV) volser. Unallocated space is percent of all the allocatable track-managed space on the volume. The amount of unallocated space remaining is tracks and cylinders. The fragmentation index fragx calculated by DFSMShsm for this volume is for information only. The storage administrator might want to reorganize volumes whose fragmentation index values are 0.6 or higher. This message describes the space available of the largest extents on the volume. The number of full cylinders in largest extent is specified as cylinders. The number of full additional tracks in largest extent is specified as tracks.
