By excluding all of the tape mount management exceptions (large, DFSMShsm, and special data sets), the remaining list has the data sets that are good tape mount management candidates. For the previous example, you would specify the following keywords:

PGM(EXC(ADRDSSU,ARCCTL))
EXPDT(EXC(98000))
DSN(EXC(*.DR.**))
JOB(EXC(VRJOB))

After you identify your tape data sets, develop a set of characteristics for them and:

• Determine the management classes
• Determine the space values for data classes
• Quantify® tape mount management benefits and costs
• Determine free space requirements
• Determine tape and cartridge configuration changes
