    The NetBackup AdvancedDisk storage option lets you use the disk storage that is attached to a NetBackup media server. (Attached means a file system mount on the storage.) NetBackup aggregates the disks into pools of storage you can use for backups. NetBackup manages the storage as logical entities (disk pools).
  • Page 18 Allows user to increase storage unit capacity by adding disks. Only add the capacity required, then update the NetBackup disk pools. Logical units of storage span physical boundaries, so you do not have to create new NetBackup storage units or change the backup policies.

  • Page 19: Licensing Advanceddisk

    You cannot create the disk pools or the storage units that reference AdvancedDisk disk pools. NetBackup jobs that attempt to use the disk pools or the storage units that are based on disk pools fail. The error message indicates that the feature is not licensed.

  • Page 20: Licensing Advanceddisk

    No special installation is required for the NetBackup components of AdvancedDisk. However, you must enter a license key. If you installed the license key when you installed or upgraded NetBackup, you do not need to perform this procedure. Enter the license key on the NetBackup master server. The following procedure describes how to use the NetBackup Administration Console to enter the license key.
