8464axStats.fm Draft Document for Review February 7, 2020 3:15 pm GLYPH<SM590000> Data Class (DC) definitions: Definition and relation to logical volume size; in this example,  800 MB and 6000 MB. GLYPH<SM590000> Storage Group (SG) definitions: Pointing the SG to the composite library definition. GLYPH<SM590000> Automatic Class Selection (ACS) routines and library definitions must also be defined, but  they are not described here. The naming convention in this case defines that all TEST volser definitions are prefixes with  TS  and PROD with  PR . ACS constructs and definitions for TEST are listed in Table I-3. Ensure that the construct  names match the names that you define on the Management Interface (MI). Table I-3 ACS construct names and important values  ACS constructs ACS construct name for TEST/PROD Important value SC for Preference Group 0 TSSCPG0/PRSCPG0 N/A SC for Preference Group 1 TSSCPG1/PRSCPG1 N/A MC for one copy in cluster0 TSMCCL0/PRMCCL0 N/A MC for one copy in cluster1 TSMCCL1/PRMCCL1 N/A DC for 800 MB volume  TSDC800M/PRDC800M Media recording must be  MEDIA2. Recording tech must be  36TRACKS. DC for 6000 MB volume  TSDC6GB/PRDC6GB Media recording must be  MEDIA2. Recording tech must be  36TRACKS. SG to relate to composite  library TSCOMP1/PRCOMP1 a Library name must match the  SMS-defined name for  composite library. a. Nomenclature derives from TEST and PROD plus composite library number.
