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)

The obsolete versions will become inactive during the next reconciliation process. See Note 1 on page 13-514.
764CSMF94VLA4binary
The total number of active logical volumes which are on VTS stacked volumes at the end of the reported hour. This number may include multiple versions of logical volumes; therefore, the number may exceed the number of defined logical volumes.

8050SMF94VEC4binary
The total estimated storage capacity of the empty 3590 cartridges managed by the VTS in an integral multiple of 1,048,576 bytes (1MByte) at the end of the reported hour. Partially filled stacked volumes are not included in this calculation. The number of empty stacked volumes is multiplied by the estimated amount of data that can be stored on one of these volumes. 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.

VVIC
4binary
Virtual volumes in cache. This four byte field contains a count, that is a snapshot taken when statistics are calculated at the end of the hour, of the number of volume assigned to the preference level that are still cache resident. For volumes that are currently mounted and do not have a preference level established (that is done when a volume is unloaded), they are credited to the count for preference level 1.

DRIC
4binary
Data resident in cache. This four byte field contains a count, that is a snapshot taken when statistics are calculated at the end of the hour, of the amount of cache space used by the volumes assigned to the preference level that are still cache resident. For volumes that are currently mounted and do not have a preference level established (that is done when a volume is unloaded), their size is credited to the count for preference level 1. The cache space is accumulated in bytes and reported in an integral multiple of 1,048,576 bytes (1 MByte).

4 Hour Rolling average tape volume cache age. This four byte field contains a rolling average cache age, in minutes, of the logical volumes that were assigned to the preference level when the volume was migrated from the cache. The rolling average is calculated based on the cache age of the volumes that have been migrated from the cache over the last 4 hours. Cache age is measured from when a volume is first closed after being created or recalled into cache until it has been migrated from cache. Each volume’s cache age is rounded up to the nearest minute. The value is calculated at the end of the hour. 16 10 2 binary

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!
Why not install a Spectrum SMF Writer trial right now and start making your own SMF reports!
