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.
