Managing Tags

Tags facilitate DCS instance identification and management.

If tag policies for DCS have been set in your organization, add tags to DCS instances based on these policies. If a tag does not comply with the policies, tag addition may fail. Contact your organization administrator to learn more about tag policies.

You can add tags to an instance when creating it or add, modify, or delete tags on the details page of a created instance. Each instance can have a maximum of 20 tags.

A tag consists of a tag key and a tag value. Table 1 lists the tag key and value requirements.
