STK VSM RTD Usage Summary (TAPLSE)
The
MICS
STK VSM RTD Usage Summary report is created from measurements in the Real Tape Drive Mount Activity (SVTRMR) AND Real Tape Drive Dismount Activity (SVTRDR) files. The report displays the usage patterns of the real tape drives by hour. Important information in this report is the maximum number of concurrent tape drives in use at any point in the hour.micsrm140
The
MICS
STK VSM RTD Usage Summary report is created from measurements in the Real Tape Drive Mount Activity (SVTRMR) AND Real Tape Drive Dismount Activity (SVTRDR) files. The report displays the usage patterns of the real tape drives by hour. Important information in this report is the maximum number of concurrent tape drives in use at any point in the hour.The report body displays the following measurements derived by combining the RTD Mount file (SVTRMR) and RTD Dismount file (SVTRDR).
- Minimum real tape drives allocated concurrently
- Average real tape drives allocated concurrently
- Maximum real tape drives allocated concurrently
- Number of unique real tape drive addresses used
- Number of real tape volumes mounted during the reporting period
- Average duration a real tape drive was allocated
- Maximum duration in time a real tape drive was allocated
- Graphic of maximum concurrent RTD usage
Usage Considerations:
Number of tape drives is a fixed resource and must be monitored and tracked. During production batch cycles, tape drives need to be available for recalling needed virtual tape volumes back to the disk buffer. Multivolume tape maintenance can be scheduled during off-peak production batch cycles.
To produce the report:
- Enter theMICS Workstation Facility(MWF)
- Choose option 2,MICS Information Center Facility(MICF)
- Choose option 2, Database Inquiries
- Select TAPLSE, whose Catalog Group is PERFORM
- Complete the MICF Execution panel
- Complete the specification panel. For information about modifiable panel fields, see StorageTek VSM MICF Inquiry Specification Panels.
The following report sample shows the usage of the real tape drives by hour by day for each host system using the VTSS resource.
