SMF Type 94 Record - Subtype 1

This table shows the record layout for type 94 SMF records
(IBM Tape Library Dataserver Statistics).

List of other SMF record layouts available.
List of sample SMF reports.

Purpose: The system-managed tape library accumulates statistics over the period of one hour. These statistics represent the activity of the IBM Tape Library Dataserver that results from all hosts attached to the library.

At the end of the hour, the system calculates composite statistics about the activity of all devices in the library and writes an SMF type 94 record.

The information in the SMF type 94 record represents:

Current Information Represents: the value of the statistic at the point the record is written.
Summary of the Last Hour Information: Represents statistics over the most recent hour for which composite statistics have been calculated.

For a VTS library, when microcode level F/C 4001 is installed and Outboard Policy Management is enabled, a new SMF94 record will be recorded. The new record is an SMF94 subtype=2, and will be recorded in addition to the existing SMF94 subtype=1. The SMF94 subtype=2 record is used to record Volume Pool Statistics.

The existing subtype=1 is also changed. When F/C 4001 is installed and Outboard Policy Management is enabled, some existing statistics will not be reported. The unreported fields will contain binary zero. Existing field SMF94HSF in subtype=1 records will contain the value 2 when F/C 4001 is installed and Outboard Policy Management is enabled.

It's easy to report on SMF 94 data! (Jump to sample reports)

We have a low-cost 4GL report writer especially for SMF files. It's called Spectrum SMF Writer.

Spectrum SMF Writer handles the difficult SMF record parsing for you automatically. You just specify which fields you want to see.

Spectrum SMF Writer also converts the arcane date and time fields and reformats them into an attractive report.

Plus, Spectrum SMF Writer can export SMF data as comma delimited files to use on your PC.

For a 3494 Model B18 without EHPO, this amount is 20 GB for the 3590-B1A tape drives and 40 GB for the 3590-E1A tape drives which is obtained by assuming a 2:1 compression ratio. For a 3494 Model B16, this amount is 20 GB for the 3590-B1A tape drives. The 3494 Model B18 VTS with enhanced ESCON host attachments provides compression into the Tape Volume Cache(TVC); therefore, further compression when writing to the stacked volume is unlikely, and the estimated amount of data copied from the TVC to a stacked volume is 10 GB for 3590-B1A tape drives and 20 GB for 3590-E1A tape drives. See Note 1 on page 13-514.

Sample Report from SMF 94 Records (IFCID=1)
Showing Tape Library System Statistics

The sample SMF report below was created with Spectrum SMF Writer, the low-cost 4GL SMF report writer. It reads as input the SMF file and selects just the type 94 subtype 1 tape library ststem records. (See SMF 94 record layout.) It selects the record for the hourly statistics for 11AM and prints various statistics for that hour.

All of this with just a few simple 4GL statements!
