Usage Guidelines
Before performing this operation, ensure that the services on the port have been stopped.
Example
Set the fast write I/O size of the Fibre Channel port whose ID is CTE0.A3.P0 to 8192 bytes. The port ID and command output vary with product models.
developer:/>change port fast_write_option fc_port_id=CTE0.A3.P0 burst_len=8192Bytes
DANGER: You are about to change the fast write I/O size of the service port. If the port to be modified has host services, this operation will cause I/O errors on the host services. If the attributes of the Fibre Channel front-end port do not match those of the peer Fibre Channel port, this operation will interrupt the connection between the host and storage system.
Suggestion: Before performing this operation, ensure that no host service is running on the port.
