Follow-up Procedure
In the HyperMetro, if the distance between the local and remote storage devices exceeds 25
km, you can run the following command to enable the fast write function to ensure link
transfer efficiency.
l FC link: By default, this function is disabled. This function is only enabled for 4-port 8
Gbit/s Fibre Channel links. You can run the change port fc fc_port_id=XXX
fast_write_enable=yes command to enable the fast write function. To obtain the value
of fc_port_id, run show port general. The function needs to be enabled on both the
local and remote storage system. Run the show port general port_id=XXX command.
When the status of Fast Write Enable in the output is Yes, this function is successfully
enabled.

You can run the change remote_device link link_type=iSCSI link_id=XXX
fast_write_enable=no command to disable the fast write function. To obtain the value of
link_id, run show remote_device link. The function needs to be enabled only on the
local storage system. You can run the show remote_device link link_type=iSCSI
link_id=XXX command to query the status of this function. When the status of Fast
Write Enable in the output is Yes, this function is successfully enabled.

service continuity.
