Convert Data Sets from Multiple to Single Volume

Use this procedure to identify multiple volume data sets and then convert them to single volume data sets.

Follow these steps:

  1. Log in to CA Chorus.
  2. Add the Investigator module to your dashboard from the Module Library, and click Start New Investigation.

    The Investigator opens.

  3. Select Storage from the discipline drop-down list.
  4. Expand the Diagnostics & Investigations, Data Set Management, Multi Volume Data Sets, Summaries directory in the Storage object tree, and open the Summary of Multvol Data Sets object.
  5. Review the content of the object display for potential candidates to convert from a multiple volume data set to a single volume data set.

    You have identified multiple volume data set candidates for conversion to single volume data sets.

    Note: Before you convert the data set, confirm that sufficient space exists on the Target Volume. The A-Trks field indicates the total number of tracks that are needed on the target volume. Record the value for the next step.

  6. Identify a volume candidate with enough space. To find a candidate volume object with the needed target space available, follow these steps:
    1. Expand the Volumes & Utilization, Volumes(DASD), Online, Space and Other Attributes directory in the Storage object tree, and open the Volume Space Usage object.

      The volumes available are displayed in the object table.

    2. Click the FrCyls and FrTrks fields column headings to find volumes with the largest space available.
    3. Record the volume name that contains the needed target space available which you want to move the multiple volume data sets to in step 10.
  7. Expand the Diagnostics & Investigations, Data Set Management, Multi Volume Data Sets, Summaries directory in the Storage object tree, and open the object Summary of Multvol Data Sets object.

    The Summary of Multvol Data Sets object opens.

  8. Select the row of the data set that you want to convert to single volume data set.

    The row of the data set that you want to convert is selected.

  9. Select Move in the Administrative Actions section of the Actions pane.

    Note: The Move action moves a data set from one volume to another, catalogs it on the new volume, and deletes the original data set. For VSAM, the cluster is copied, not just the component.

    The Move action displays the Action dialog which provides the following options:

    New data set name (optional)

    Specify a new name to give to the data set.

    For VSAM, specify the new cluster name, not a component name.

    To Volume

    Specify the new target volume for the data set. (The volume name that you recorded in step 7.)

    Catalog (Y/N)

    Select this check box for Y. This indicates that you want the moved data set to be cataloged.

    Replace (Y/N)

    Clear this check box for N. This indicates that you do not want to replace the data set if it exists on the target volume.

  10. Click Submit.

    The specified action is performed.

  11. Repeat steps 6 through 10 for each data set that you want to convert to single volume.

    Multiple volume data sets are converted to a single volume. You have simplified management of these data sets and reduced the likelihood of confusion.
