zPulse · Tape · Formerly EATM
zPulse Tape counts virtual tape mounts per LPAR, follows the response time of virtual tape, reads your TS7700 VEHSTATS files and your tape catalogue to show volumes and capacity by tape type. It replaces EATM, with scheduling and a daily mail.
A tape analysis on z/OS has two halves. One is activity: mounts, response time and cache behaviour of virtual tape. The other is content: how many volumes are active or scratch, and how much capacity your cartridges use. zPulse Tape covers both, from your tape management catalogue, your RMF and CMF reports and your TS7700 statistics.
zPulse Tape is the module for tape and virtual tape. It reads your tape management catalogues, TS7700 statistics and the tape activity in RMF and CMF reports, and keeps the catalogue between scheduled runs.
What it analyses
Virtual tape mounts per LPAR over time, with a device type filter, and the virtual and physical mounts of each TS7700 cluster from VEHSTATS.
Tape I/O stacked by LPAR with response, connect, disconnect, IOSQ and pending time, from RMF or CMF tape device activity.
Cluster CPU use, cache throughput and throttling, read and write volume, physical mounts and virtual drive use, from VEHSTATS files.
Active and scratch volumes, single and multi-volume files, used and available capacity, with one set of columns per tape type and a DFHSM column.
Filter by dataset name, volser (with * wildcards) and last change date. Capacity Config sets the volser ranges, tape types, compression and capacity.
The catalogue accumulates between runs. The scheduled tape study writes a capacity workbook that the Tape Management Xlsx tool charts over time.

Data
zPulse works from the reports and files you already produce. Nothing is installed on z/OS.
| Record or file | Report | What zPulse uses it for |
|---|---|---|
| DFSMSrmm, CONTROL-T/M, CA-1 | Printed tape management catalogue | Active and scratch volumes, files, used and available capacity, by tape type. |
| VEHSTATS | TS7700 HOURxxxx files | Cluster utilisation, cache throughput and throttling, virtual and physical mounts, read and write volume, virtual drives. |
| RMF and CMF | Magnetic Tape Device Activity (RMF), Tape Activity (CMF) | Virtual tape mounts per LPAR, response time components and I/O rate. |

Tools
Tools open a report or a folder and show charts and tables on one subject. Each card of the catalogue says which file the tool reads.
Automatic studies
A scheduled tape study can send a standard report with volumes and capacity by tape type, a tape performance mail with response time charts, and a VEHSTATS mail with the cluster charts. The period covered is in each subject. These mails do not chart a 60-day history: that is for the DASD and CPU mails.
EATM followed your tape management system, robotics and virtualisation, and published fill rates as reports. zPulse Tape keeps the catalogue analysis and adds virtual tape mounts, response time and TS7700 statistics.

Period: 7 Oct 2026 · Charts are in the body of the mail, with no attachment.
FAQ
Tape management catalogues in text form (DFSMSrmm, CONTROL-T/M and CA-1), TS7700 VEHSTATS files, and the tape device activity in your RMF or CMF reports.
Yes. VEHSTATS Report shows the virtual and physical mounts, cache total and cache throttling, and virtual drive use for the TS7700 clusters.
The catalogue study works on your tape management catalogue, with one set of columns per tape type. The mounts and response time views cover virtual tape, and VEHSTATS covers the TS7700.
zPulse reads DFSMSrmm, CONTROL-T/M and CA-1 catalogues. If you use another tape management product, ask us before assuming it works.
No. zPulse reads the report and catalogue files you already produce. It runs on its own server.
