6.2.4 IBM Hydra Bulk Volume Information Retrieval (BVIR)

 With the new generation of IBM virtual tape servers--the
 TS77xx series--the statistics are no longer sent to the
 attached hosts as SMF records. They are written to an
 internal database within the TS77xx itself.  Both
 point-in-time and historical records are stored.
 Point-in-time records contain the operations activity over
 the last 15 seconds for real-time dashboard reporting at the
 device itself.  Historical records contain the operational
 statistics at 15-minute intervals and are stored for 90 days.
 
 The CA MICS Tape Analyzer Option processes the historical
 records.  The historical data is obtained by a BVIR request
 to the server to extract the data.
 
 The following sections describe the historical record and
 strategies for collecting the data.
