    VCS will not automatically recognize and monitor the new volume.
    You will need to add another resource for the new volume.

    Each volume in the DG needs own Volume resource. 
    Same as each mount point needs a separate Mount resource.

    The DiskGroup agent does not monitor volumes.
    There is a separate Volume agent for volumes.

    You can set the DiskGroup attribute StartVolumes and StopVolumes to 1. 
    This means that the DiskGroup agent brings the volumes online and takes them offline during the import and
    deport operations of the disk group, but it will not monitor volumes.
    Add Volume type resources for each volume in the DiskGroup and a Mount resource for each volume (if you want VCS to mount and monitor the filesystem).

    When you create a new DG, you need to add a new DiskGroup resource in the relevant Service Group.
    One DiskGroup resource per DG.

    Please see the VCS Bundled Agent Guide for detailed information and attributes of DiskGroup and Volume agents, along with sample resource/dependency trees.

    Hope this helps.

     

    PS:

    I have moved this discussion to Cluster Server forum since your query is about VCS agents.
