- Sets the specified attribute of the slice (or sliver, if
- node_id_or_hostname is specified) to the specified value.
+ Sets the specified tag of the slice to the specified value.
+ If nodegroup is specified, this applies to all slivers of that group.
+ If node is specified, this only applies to a sliver.
+
+ Admins have full access, including on nodegroups.
- Attributes may require the caller to have a particular role in
- order to be set or changed. Users may only set attributes of
- slices or slivers of which they are members. PIs may only set
- attributes of slices or slivers at their sites, or of which they
- are members. Admins may set attributes of any slice or sliver.
+ Non-admins need to have at least one of the roles
+ attached to the tagtype. In addition:
+ (*) Users may only set tags of slices or slivers of which they are members.
+ (*) PIs may only set tags of slices in their site
+ (*) techs cannot use this method
Returns the new slice_tag_id (> 0) if successful, faults
otherwise.
