Use tags to encode information about a datastore. The tags are helpful when your datastore is not represented by a storage provider and does not advertise its services in the VM Storage Polices interface. You can also use the tags to indicate a property that is not communicated through a storage provider, such as a geographical location or administrative group.

You can apply a new tag that contains general storage information to a datastore. For more details about the tags, their categories, and how to manage the tags, see the vCenter Server and Host Management documentation.


Required privileges:
  • vSphere Tagging.Create vSphere Tag on the root vCenter Server instance
  • vSphere Tagging.Create vSphere Tag Category on the root vCenter Server instance
  • vSphere Tagging.Assign or Unassign vSphere Tag on the root vCenter Server instance


  1. In the vSphere Client, create a category for storage tags.
    1. From the Home menu, click Tags & Custom Attributes.
    2. Click the Tags tab and click Categories.
    3. Click the Add Category icon.
    4. Specify the category properties. See the following example.
      Category Property Example
      Category Name Storage Location
      Description Category for tags related to location of storage
      Tags Per Object Many tags
      Associable Object Types Datastore and Datastore Cluster
    5. Click OK.
  2. Create a storage tag.
    1. On the Tags tab, click Tags.
    2. Click the Add Tag icon.
    3. Specify the properties for the tag. See the following example.
      Tag Property Example
      Name Texas
      Description Datastore located in Texas
      Category Storage Location
    4. Click OK.
  3. Apply the tag to the datastore.
    1. Navigate to the datastore.
    2. Right-click the datastore, and select Tags & Custom Attributes > Assign Tag.
    3. From the list of tags, select an appropriate tag, for example, Texas in the Storage Location category, and click Assign.


The new tag is assigned to the datastore and appears on the datastore Summary tab in the Tags pane.

What to do next

When creating a VM storage policy, you can reference the tag to include the tagged datastore in the list of compatible storage resources. See Create a VM Storage Policy for Tag-Based Placement.

Or you can exclude the tagged datastore from the VM storage policy. For example, your VM storage policy can include Virtual Volumes datastores located in Texas and California, but exclude datastores located in Nevada.
