The datastore mustsatisfy at least one rule set and all rules within this set.8 Confirm that the policy information is correct and click Finish.The new storage policy appears on the list of available policies.What to do nextApply the policy to a virtual machine home file and its virtual disks.Add Tag-Based RulesWhen you define or edit a storage policy for virtual machines, you can create a rule that references tags thatyou used for particular datastores. The datastores become compatible with that type of storage policy.When you use tags in the policies, follow these guidelines:• If the rule set contains other rules, the datastore with the assigned tag must satisfy all of the rules in therule set.• If you add several tags from the same category within the same rule, the tags are treated as alternativeconstraints. Either of the tags can be satisfied.• If you add the tags in separate rules within the same rule set, all tags must be satisfied.PrerequisitesCreate storage tags and apply them to datastores. See “Assign Tags to Datastores,” on page 196.Procedure1 On the Rule Set page, click the Add Tag-Based Rule button.2 Select a category from the Categories drop-down menu.3 Select a tag or multiple tags from the list of tags.Datastores that use the tags that you selected become compatible with the storage policy.VMware, Inc. 199
