zFS Candidate Volumes

You can use a zFS candidate volume when your environmental setup dictates that zFS container data sets are directed to the specified volume.

When your environmental setup dictates that zFS container data sets are directed to specified zFS candidate volumes, use one or more of the candidate volumes. CA CSM uses the candidate volumes in the IDCAMS statement to create the zFS container VSAM data set.

The zFS candidate volumes are only required if the following statements are true:

• Your deployment has USS parts.
• You are doing a container copy.
• You selected zFS as the container type.
• The remote system requires it.

  Note: Remote system requirement is customer defined.

To allocate and maintain your disk, the following products are recommended:

CA Allocate

CA Allocate is a powerful and flexible allocation management system that lets the Storage Administrator control the allocation of all z/OS data sets.

CA Disk Backup and Restore

CA Disk is a flexible, full-featured hierarchal storage management system.

You can also use the following standard IBM techniques:

• Allocation exits
• ACS routines

If you do not implement any of these options, z/OS needs a candidate list of volumes for placing the zFS archive.
