Volume List screen (I)
The following figure displays information such as space usage for single or multiple volumes. It does not show lists of data sets; the data set lists are displayed by entering the S or M line commands as described in Line Commands.
The Volume List screen is displayed by selecting option I on the VTOC Utility screen. A search dataset name mask can be specified. However, the volumes are displayed on the list whether or not they contain any data sets that match the mask. Only by selecting the volume for display (line commands S or M) will the data sets be shown and counted.
The top line of the Volume List screen shows the volume selection parameter values that were specified in the VTOC Utility screen, and the number of volumes in the displayed list. The volume information is displayed in columns.
Line Commands
Two line commands are valid on this display screen:
S
Displays a data set list for the selected volume in dataset name sequence (see Utility VTOC List Screen - Dataset Name Sequence).
M
Displays a data set list for the selected volume in volume-location sequence (see Utility VTOC List Screen - Volume-Location Sequence).

Utility VTOC List Screen — Dataset Name Sequence
The Utility VTOC List screen, shown in the following figures for EAV, lists the volumes in dataset name sequence. The screen is scrollable. If no dataset name matches the specified name, File-AID displays the message: NO DATASET FOUND in the upper-right corner of the Utility VTOC List screen.
The Utility VTOC List screen — Dataset Name Sequence is displayed by entering the S line command to the left of a volume on the Volume List screen. Entering the M line command on the Volume List screen displays the VTOC List screen — volume-location sequence (see Utility VTOC List Screen - Volume-Location Sequence).

The top line of the Utility VTOC List screen displays the disk pack name with the type (in parentheses), and the number of data sets in the list.
When Display Volume Summary is set to Y, the volume summary information is displayed in the following lines, beginning with the headings: VTOC, VOL, and FREE. A fourth volume information line is displayed if a generic search is specified.
The next four lines only display for EAV DASD (see Utility VTOC List Screen - Dataset Name Sequence for EAV DASD) and show track- and cylinder-managed free space information.
Data set information is organized in columns below the volume summary information.
If required, scroll down the data set list to the desired data set. VTOC Utility Line Commands lists the line commands that you can enter on a list of dataset names.
Press END (PF3) to return to the VTOC Utility screen.
