SVTRPR - Real Tape Drive Performance Request File

At the DETAIL timespan, the Real Tape Drive Performance Request File contains performance information for real tape drives.
micsrm140
The Real Tape Drive Performance Request File is derived from the StorageTek user SMF record, subtype 20 interval record, 'RTD Performance Request'. This record is produced at 15 minute intervals and contains utilization statistics for each real tape drive, including the volume of data read and written.

File Organization

The table below 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.

This file was generated with ESSENTIAL=ALL option in effect. All data elements that are defined in the file are generated.
This file was generated with DERIVED=DEFault option in effect. The complex definition of the DERIVED option controls whether the data elements are kept on the file on auxiliary storage.

Usage Considerations

The SVTRPR file can be used to monitor trends for the real tape drives assigned to the VTSS. An interesting analysis is to determine if the I/O is balanced across all the assigned tape drives.

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.
