Storage Class Synchronization Service


The Storage Class Synchronization Service identifies data sets whose existing storage class is different from the storage class that would be assigned by the current ACS routines or SMSACSxx rule lists.

See the following sections in this topic for more information:

What you can do with the service

The Storage Class Synchronization Service synchronizes data sets to new or changed storage class assignment rules.

To change the storage class of a data set, generate control cards for the IDCAMS ALTER command.

Organization of the service

The Storage Class Synchronization Service does not produce a report.

The control card generation facility is used with the service to build control cards to change the storage class of the selected data sets.

Usage notes for creating the service

Consider the following information when using the Storage Class Synchronization Service:

  • The BMC AMI Storage subsystem must be executing to run the Storage Class Synchronization Service.
  • All selected data sets are processed by the SMS storage class ACS exit and the SMSACSSC function. If the returned storage class differs from the storage class that the data set already has, control cards are generated; if the returned storage class is the same as the data set’s current storage class, control cards are not produced.

    Warning

    Important

    Even though the data set has been reprocessed by the ACS exit and SMSACSSC function, its storage class is not changed by the synchronization service. To make a change, set up the generated control cards to alter the storage class.

  • Regardless of whether the SMSACSSC function is running in active, simulated, or inactive mode, the function still processes the data sets that are specified in the reporting INC statements. However, if the function is deactivated in the SMFUNCxx member by ACTIVE=NO, the function does not process any data sets. The SMSMANAGED parameter of the SMSACSTE function has no effect on the report.

    Success

    Tip

    Many BMC AMI Storage selection parameters are not available to the SMSACSxx functions filter and rule lists during the synchronization service. For more information, see Management-Class-Synchronization-Service.

  • During the implementation period, the AP master data sets have been assigned the STANDARD storage class.

    Now, the SMSACSSC rule list has been modified to assign production storage classes to AP data sets.

    The following SCS specification will generate the indicated cards:

    EXCLUDE MIGRATED DS = YES
    REPORT TYPE=SCS
    INCLUDE DSN=AP*.MSTR*./
    GENERATE CARDS DD=CARDOUT
    ALTER &DSN -
       STORAGECLASS(&SCNAME)

    cards:

    ALTER AP00M5.MSTRDLY.UPDTRN -
        STORAGECLASS(DBCRIT)
    ALTER APYTD.MSTRANNL.VNDRS -
        STORAGECLASS(FASTREAD)
