7.2.1 VTS Component Environmental Considerations

In preparation for defining VTS component complex and unit
level parameters, do the following:

o Review database unit specifications to determine which unit
  or units should process data from virtual tape subsystems.

o Review the SYSID parameter to ensure that it correlates to
  the systems where you plan to collect SMF data for your
  virtual tape systems.  Your site's SYSID definition is
  located in the prefix.MICS.PARMS data set associated with
  each database unit.

  Reference: Section 6.2.1.2 for IBM VTS
             Section 6.2.2.2 for StorageTek VSM

  NOTE:  If the VTSUTIL job report, described in section
  6.2.1.2, shows the presence of IBM peer-to-peer VTSs, make
  sure you review Section 7.2.3.3 - VTS Peer-to-peer
  Libraries (VTSCMPID) in this chapter to familiarize
  yourself with the required prefix.MICS.PARMS(VTSCMPID)
  member update.

o Review the default options for the parameters to determine
  their applicability to your site.

o Before running the component generation job,
  sharedprefix.MICS.CNTL(VTSCGEN), edit
  sharedprefix.MICS.GENLIB(VTSGENIN) and update the following
  statements to reflect the virtual tape system(s) providing
  input to the component:

  OPTION <keywords>
  INPUTSOURCE SMF <SMF record types>

  Failure to update these statements will result in
  inefficient daily update processing.
