TSM server V5.1.6.2 on z/OS. Can someone explain why these numbers from a Q DB F=D don't "add up" (at least they don't make sense to me ?):
Available Space (MB): 35,160 Assigned Capacity (MB): 35,160 Maximum Extension (MB): 0 Maximum Reduction (MB): 5,372 Page Size (bytes): 4,096 Total Usable Pages: 9,000,960 Used Pages: 4,968,239 Pct Util: 55.2 Max. Pct Util: 55.2 Physical Volumes: 15 In summary, it says that of the roughly 35GB DB, only 55% is used. In round numbers, 20GB is in use. This means that 15GB is not. However, the "Maximum Reduction" value is 5GB. Where is the other 10GB ? Even if TSM kept the "reduction" values based on the volume sizes (roughly 2.3GB per 3390-3 volume is what it is reporting), I should still be able to reduce the size by 6-volumes, or roughly 13GB !
