5.2.4 VTS Component HVT Information Area Files

 
This section identifies each file in the IBM TS7700 Hydra
 Virtual Tape Servers (HVT) information Area and defines its
 levels of summarization and data sequencing.  The active data
 elements for each file are also listed.
 
 IMPORTANT NOTES:
 
 o The performance statistics for the TS7700 are not written
   to SMF.  They are stored in a database on the TS7700 itself
   and are retrieved using the Bulk Volume Information
   Retrieval (BVIR) facility.  See the IBM Virtualization
   Engine TS7700 Series Bulk Volume Information Retrieval
   Function Users Guide for information on extracting the
   Historical Performance records.
 
 o There is no host identification in the Historical
   Performance records.  The statistics pertain to the
   activity of the TS7700 Virtual Tape System itself.  CA MICS
   components require a SYSID value.  The SYSID value used is
   specified with the VTSSYSID statement in
   prefix.MICS.PARMS(VTSOPS).  If it is not specified, a
   default value of 'SYS1' is assigned to the SYSID data
   element.  See section 7.2.3.1.3 for more information.
