Follow-up Procedure
If error code
1073804034
occurs or the connection fails to be created, see the case What Can I
Do If the Remote Connection Fails to Be Created with the TOE Interface Module in FAQ.
After an iSCSI replication link is established, run
change iscsi target
and
change initiator
on
the primary and secondary end (For details about how to use these commands, see the
Command Reference
of the corresponding product model.) to enable CHAP authentication for
the iSCSI replication link. If CHAP authentication is not enabled, spoofing may occur
between primary and secondary storage systems.
In the synchronous remote replication, 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.
l
iSCSI link:
By default, this function is enabled. You are advised to enable this function. You can run
the
change remote_device link link_type=iSCSI link_id=XXX
fast_write_enable=no
command to disabled 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.
