Creating a BVIR dataset

The TS7700 series VTS controllers write statistical data to virtual tape volumes in response to a request written first on the same volume. This is referred to a Bulk Volume Information Retrieval (BVIR).

OMEGAMON® for Storage writes a BVIR request and collects and analyzes the response data at every VTS collection interval. If you are experiencing a problem with VTS reporting on TS7700 series devices and the matrix says you must submit a BVIR dataset, you can submit JCL similar to this:

//STEP1 EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN   DD DUMMY
//SYSUT2  DD DSN=bvir_virtual_tape,
//  DISP=(NEW,CATLG,DELETE),UNIT=ts7700_unit,
//  DCB=(RECFM=F,LRECL=80,BLKSIZE=80,TRTCH=NOCOMP)
//SYSUT1 DD *
VTS BULK VOLUME DATA REQUEST
HISTORICAL STATISTICS FOR 297
/*
//STEP2 EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN   DD DUMMY
//SYSUT1  DD DISP=bvir_virtual_tape,
//  VOLUME=(,,REF=*.STEP1.SYSUT2),
//  DCB=(RECFM=U,BLKSIZE=24000)
//SYSUT2 DD DSN=bvir_dataset_to_support,
//  DISP=(,CATLG,DELETE),SPACE=(CYL,(5,5)),
//  UNIT=SYSDA,DCB=(RECFM=U,BLKSIZE=24000)

The first step writes the request to a virtual tape. Name the tape appropriately and specify a UNIT parameter which assures the data will be written to the TS7700 device. The controller will immediately write the response data and it will be read in STEP2 and written back out to a dataset on disk that you can TERSE and submit to IBM® Software Support.
