The function performed is based on the Option Code specified.

• I – List volume information is displayed for each of the selected volumes.
• E – A list of DSNs within the selected volumes that match the specified wildcarded DSN appears. For any data set in the list, you can access various CA File Master Plus functions.

You can use the Volume Selection Information section of the screen to specify the volumes to be involved in the processing based on a list of Volume serials or wildcarded Volume serials and a list of Unit names or wildcarded Unit names. Any volume that matches the specification in either the Volume serial list or the Unit name list is selected for processing.

When the option is 'I', List volume information, a screen appears which has the following information for each selected volume:

• Volume Serial Number
• Volume Device Type (such as 3380, 3390, and so forth)
• Percent of Volume Used
• Mount Status (STG=storage volume, PUB=public volume, PRV=private volume)
• Total Free Cylinders
• Max Free Cylinders - largest available contiguous free cylinders
• Total Free Tracks
• Max Free Tracks - largest available contiguous free tracks
• Num Extents – number of free extents
• SMS – indicates if the volume is SMS managed. 'SMS' indicates that the volume is SMS managed.
• EAV – indicates if the volume is an Extended Address Volume, 'EAV' indicates that the volume is an Extended Address Volume.

The displayed information is helpful to summarize the status and free space for each volume within the selected group of volumes. You can select a volume to receive a VTOC Utility Data Set List that displays all of the data sets within that volume, from the Volume Summary screen.

When the option is E to request the VTOC Utility Data Set List, a screen appears that has a line item for each of the data sets within the selected volumes that match the wildcarded DSN (if specified). Each line item presents the following information about each data set:

• Data Set Organization (such as PS for seq, PO for PDS, and VS for VSAM)
• Number of Tracks Allocated
• Percent of Tracks Used
• Volume Serial Number

Page RIGHT to view the following fields relating to each data set:

• Record Format (such as FB, VBA, U, and so forth)
• Logical Record Length
• Block Size
• Number of Extents Allocated
• Created Date
• Last Referenced Date

From the VTOC Utility Data Set List that was accessed using an option of E, you can access the following facilities:

From the VTOC Utility Data Set List, you can print the list of data sets and all of the fields on each line item with a primary command of P.
