| 383 | A free form string, optionally returned per sliver from several method returns (`Describe`, `Provision`, `Renew`, `Status`, `PerformOperationalAction`, `Delete`). The aggregate manager should set this to a string that could be presented to a researcher to give more detailed information about the state of the sliver if this operation fails for a given sliver. This option is used in particular where an aggregate may successfully perform the operation for some slivers, but not others. See the `geni_best_effort` option above. |
