You can create a bucket via VMS by creating a view and enabling S3 Bucket as a protocol. When creating a bucket this way, you specify a user as a bucket owner.
To create an S3 Bucket view, follow the VAST Web UI or VAST CLI procedure in Creating Views to create a view and make the following settings:
Select S3 Bucket as a protocol.
Set the name of the bucket if you wish. Otherwise, the view's path will be used as the bucket name.
Set the bucket owner to the user name of a user that has an entry on a provider such as Active Directory or the local provider.
Optionally, enable S3 features.
