Problem:

The following message is logged in vRO when running the 'Ad Hoc Backup' workflow:

(com.hitachivantara.protector.backup/performAdHocBackupOf) Error in (Dynamic Script Module
        name : performAdHocBackupOf#9) MasterException[failed to associate Tag [name: Protector Ad
        Hoc, Id: urn:vmomi:InventoryServiceTag:...] to VM [vm-...],
 Cause:
        VMwareException[Tagging cardinality violation] ]

Cause:

For the vRO Ad Hoc Backup Workflow to work, it needs to tag the desired VM with the ‘HDID/Protector Ad Hoc’ tag.

The error ‘Tagging cardinality violation’ indicates that the VM already has a tag that belongs to the same tag category as the 'HDID/Protector Ad Hoc' tag. And that this tag category is restricted to “Tags Per Object: One tag”. As such only one tag from the category can be assigned to the desired VM.

Solution:

Move the 'HDID/Protector Ad Hoc' tag into its own category.

If you cannot create a new category, then alter the category tag cardinality such that “Tags Per Object” is “Many tags”. (See screenshot below)
