Create and Define a Dynamic Logical Group

A dynamic group uses selection criteria (filters) to automatically determine which drives and media to include in the group.

When drives and media meet the selection criteria for a group, they are automatically added to the group, and when they no longer meet the criteria, they are automatically removed. Dynamic groups update automatically every hour.
  1. In the left navigation, expand Setup & Administration, select Logical Groups.
  2. Click Add Logical Group Add Logical Groups icon.
  3. Complete the Create Logical Groups dialog:

    • Logical Group Name — Enter a unique name for the group using up to 250 alphanumeric characters (for example "LTO5- Drives").

    • Logical Group Type — Select Dynamic.

    • Entity Assignment Rules — Select filter criteria for the group (Dynamic Group Selection Criteria). See Filter Using the Dialog Box on how to define a filter.

      For example, if you wanted all LTO5 drives, you would create this filter:

      Sample Entities Assignment Policies dialog.
  4. Verify that your criteria are correct and click Save.
  5. Initially, the media and drive counts for the group are 0. Click Refresh Table Refresh icon to update the drive and media counts.

    Depending on the size of your tape library system and the complexity of the selection criteria, it may take several minutes to add all drives and media to the group. Leaving the Logical Groups screen does not interrupt this process.
