Issue/Introduction

I did not find any specific information about these 2 datasets maintenance.
These are multi-volume dataset and reached 123 extends on the volumes they are currently allocated.
 
As far as I understand they are used for Tape device usage statistics:
MPMDEVDA  - MEDIA PERFORMANCE MONITOR - DAILY 
MPMDEVDH  - MEDIA PERFORMANCE MONITOR - HOURLY

Is there any parameter or any JOB that should be running to delete the OLD tape device information for each of them?

Both data sets (actually all MPM data sets) are VSAM KSDS. The key for all of them starts with the year. So, they can do it for example like this: 
1) Allocate new set of MPM data sets (or just those 2 they mentioned). They can use job J07MEDIA in CCTUSAMP library, step MPMALLOC 
2) Copy only some records to the new data set(s). FROMKEY(2015*) parameter defines that only records from year 2015 to 2018 will be copied. The job can look like this: 
//******************************************************* 
//* REPRO MPM CLUSTERS 
//******************************************************* 
//REPRO EXEC PGM=IDCAMS,REGION=1024K 
//SYSPRINT DD SYSOUT=* 
//SYSIN DD * 
REPRO INDATASET(oldvsam.MPMDEVDA) - 
OUTDATASET(newvsam.MPMDEVDA) - 
FROMKEY(2015*) 

REPRO INDATASET(oldvsam.MPMDEVDH) - 
OUTDATASET(newvsam.MPMDEVDH) - 
FROMKEY(2015*) 

3) Change Vantage parameter(s) MPMDEVDA, MPMDEVDH, MPMDEVDS, MPMVOLDS to point to the new smaller data sets and restart Vantage host. 

Or they can rename the original VSAM data sets, create the new one with the original name etc.
