The percentage of DASD used for the total blocks in use (1-UP listing only). This field indicates how effectively the DASD space is used to store members.
Utilization percentages of 10-20% indicate that large areas of DASD blocks used to store members are being wasted.
Many small members in the library or creating the library with too small a RECORDS=nn parameter can cause the poor use of space.
The greater the utilization percentage, the more effective the use of library space. For more information, see %UTIL in PRINT Command.
