DN Command—Display Volume Status and Data Set Charactersitics

Use the DN command to display information about a volume by specifying the name of a data set. (The data set must be in the CA TLMS VMF Index file.) This information includes:

• Volume status (scratch status, CDS number and so on)
• Data set characteristics (BLKSIZE and so on)

This is the same display you will see if you use the DV command, except you do not have to know the volume serial number.

This command has the following format:

DN DSN=dsn [VER=n]

DSN=dsn

Specifies the name of the data set. You will see the most current version of the data set, unless you specify VER=v.

VER=n

(Optional) Specifies the relative version number if you want to see a specific version of the data set. The most current version of the data set is version 1, the one created before that is version 2, and so on.

Note: When an optional parameter is specified, it must be separated from the data set name by a space; a comma is not valid.

Example: JCL for the Current Version

//TLMSINQR  JOB
//TLMSINQR  EXEC CATINQR,MODE=BATCH
//CAIIPT    DD   *
DN DSN=SVTS.TGRP51.P0106.DAT22

This JCL produces this display:
