NOTE
l On a Fibre Channel network, clear zone configurations of ports connecting to the storage system
from the switch before adding the remote device. You are advised to allocate two ports in one zone
to prevent excessive remote links because too many ports exist in one zone.
l
A maximum of eight available links can be identified between a controller and the remote device,
and at most eight of these links can be used for replication when you add a remote device.

NOTE
When a large number of remote storage devices exist, you can select desired remote devices through
their WWNs. Click Home on DeviceManager. In the Basic Information area, you can view WWN.
NOTICE
If Running Status of an added link is Invalid, delete and add the link again.
To ensure data transfer security among storage systems, you are advised to use a device
such as a security gateway to encrypt links to prevent information leakage.
If the version of the local device is different from that of the remote device, you need to
add a remote device on the newer version device. Otherwise the operation may fail.
In HyperMetro scenarios, the two storage arrays need redundant links. Therefore, add
two Fibre Channel links or iSCSI links.
Add an iSCSI Link
a. Set Link Type to iSCSI.
b. Set parameters for the iSCSI link.
