a: The user used for communication authentication between remote devices.
l If remote devices are OceanStor 18000 series V1R1C20, T series V2R2C20, or
OceanStor V3 series V3R1C10 or later, you need to use the machine-machine user. The
default username and password of the machine-machine user are mm_user and
mm_user@storage respectively.
NOTE
You are advised to change your login password periodically in the future by executing the change
mm_user password command. This reduces the password leakage risks. For details on using the
command, see the Command Reference of the corresponding product model.
l If remote devices are OceanStor 18000 series V1R1C10, T series V2R2C10, or
OceanStor V3 series V3R1C00 or earlier, you need to use the super administrator or
administrator account on an earlier version of a remote device. The username and
password of the super administrator or administrator account are consistent with those
on the remote device.
NOTE
l Keep the default values of the parameters that are not mentioned in this table.
l 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.
4.1.3 Configuration Operations
After completing the network and service plans, configure the remote replication feature on
the DeviceManager according to the plans.
