The StorageTek VTSS Summary File is a combination of several files dividing the data into 15 minute intervals. It provides a central repository for the most common system summary reporting needs. It is derived by a merge of the following detail level work files:
  • SVTVMR - Virtual Tape Volume Mount Activity
  • SVTVDR - Virtual Tape Volume Dismount Activity
  • SVTVGR - Virtual Tape Volume Migrate Activity
  • SVTVRR - Virtual Tape Volume Recall Activity
  • SVTRMR - Real Tape Drive Mount Activity
During this merge of event and interval driven data, the observations are placed or summarized into one of the following intervals based on the value of their end timestamp (ENDTS): 00:00 - 14:59, 15:00 - 29.59, 30:00 - 44.59, 45:00 - 59.59.

File Organization

The following table identifies data elements by which the file is sequenced and summarized in each timespan. N/A indicates that the file is not supported in a timespan. At the DETAIL level, data is sequenced but not summarized.
The timespans in which a file is supported are defined by each installation when
MICS
is installed. Therefore, this table has been generated as part of the installation process to accurately reflect the
MICS
system at your installation.

Usage Considerations

This section identifies any special considerations or techniques related to using the SVTSVS file.
The SVTSVS file is generated from a mix of files representing both interval level statistics and event data. For data elements associated with events, missing values will result if no events occurred during the interval.
If the values for particular metrics are always missing, it might be that the source SMF record subtypes are not being recorded. Consult with the VSM Storage Administrator and review the SMF parameters for VTCS in SYS1.PARMLIB to verify which records are recorded.
In addition, data element SVSMASK, in the DETAIL timespan indicates the SVTfff records that contributed to the observation. Each byte of SVSMASK represents whether a particular SVTfff file contributed to the SVS file observation. See the data dictionary description for SVSMASK for the mapping of SVTfff file pertains to each SVSMASK byte.

Retrieval Examples

In the examples, a SAS macro variable is used to specify the DDname part of the
MICS
file name. These macro variables are a standard part of
MICS
and are available for all files. The macro variable name has the form &diiit, where d is the database identifier, iii is the information area name, and t is the timespan. For the examples, a database identifier of P is used. The identifier is installation-dependent, so you should find out what the identifiers are at your installation.
  • Generate a report displaying virtual cache mount statistics and recall statistics, by hour, from the DAYS timespan. This report shows the total virtual mounts, number of scratch, cache hit, cache miss mounts, percentage relationships and minimum, maximum, and average mount times. It also shows specific metrics on the time to mount a recalled volume.
