Use the UPD command to update volume data in the Volume Master File.
This command has the following format:
UPD volser keyword=value [,keyword=value]...
Specifies the volume serial number.
Each value in the Volume Master File has a keyword associated with it. To change the value, code the keyword followed by an equal sign and the new value.
Note: For information on keywords and their values, see the section VMF Keywords.
You can code multiple keywords on the same command, ending before position 72. Separate keywords with a comma or a space after the value.
To delete a value, code the keyword followed by a comma or a space; for example CJOB=, or CJOB= .
To change dates, specify the date in either Julian or preferred date format. For EXPDT, use TLMS keywords. If the preferred date format contains blanks or commas, enclose it in single quotes or parentheses.
When you issue this command, you get a printout of the new dataset information, which you can verify.
If you are updating values for a data set that is contained on multiple volumes, you must specify the UPD command for each volume that contains the dataset.
If there is more than one dataset on the volume, use the FILESEQ keyword to give the relative file number of the dataset.
Example: JCL for the UPD Command
//TLMSINQR JOB //TLMSINQR EXEC CATINQR //CAIIPT DD * UPD 001511 BLKSIZE=4800 //
This example changes the block size for the dataset on volume 001511 to 4800.
This JCL produces this display:
VSN=001511 VOLSEQ=001 VOLCNT=001 OWNER= SERVICE=IN SCRATCH=YES CDS=00000 FILECNT=00001 * DSNAME=SVTS.TGRP51.P0106.DAT22 VER= USER=121400000 FERRO15 BLKSIZE=004800 LRECL=00080 RECFM=FB MGMTCLAS= BLKCNT =000000003 FILESEQ=00001 CPU=XE90 BESKEY=00000 KEEPDT =09/25/2008 EXPDT=09/18/2008 BASEVOL=001511 CDATE =09/18/2008 CUNIT=078A CJOB=GENDAT20 CSTEP=STEP02 CTIME =15.45.26 ABEND= CPGM=IEBDG CDDN=OUTPUT LDATE =09/18/2008 LUNIT= 078B LJOB=GENDAT20 PERCENT 001 00
