ONTAP Error Response Codes

Error Code Description

72089705

The NVMe subsystem host already exists for the NVMe subsystem.

72089771

The NQN is invalid. A non-empty qualifier is required after the prefix. An example of a valid NQN is nqn.1992-01.com.example:string.

72089772

The NQN is invalid. Add the prefix 'nqn'. An example of a valid NQN is nqn.1992-01.com.example:string.

72089773

The NQN is invalid. The date field must be formatted yyyy-mm. An example of a valid NQN is nqn.1992-01.com.example:string.

72090002

The POST request of hosts to an NVMe subsystem can only contain an 'nqn' property or 'records' property, but not both.

72090003

The elements in the records array for a POST of hosts to an NVMe subsystem must contain only the nqn property.
