Usage Guidelines
Before performing this operation, ensure that the services on the port have been stopped.
Example

If the burst length of fast write of the Fibre Channel host port mismatches that of the Fibre Channel port on the peer end, this operation interrupts the connection between the host and storage system. Suggestion: Before perform this operation, you are advised to confirm that no host service running on the port. Have you read danger alert message carefully?(y/n)y Are you sure you really want to perform the operation?(y/n)y Command executed successfully.
