Method used to change the IP address of a cluster
FusionInsight HD allows you to change the service plane IP address, management plane IP address, and OMSServer IP address of a node. After the modification, you do not need to reinstall the cluster or restore the data. However, the dual-plane isolation networking and single-plane networking switchover scenarios are not supported. For details about how to change the IP addresses, see "Administrator Guide > Cluster Management > Changing IP Addresses" in the FusionInsight HD V100R002C80SPC200 Product Documentation.

Method used to configure UltraPath in the cluster environment
You can configure UltraPath in the cluster environment as follows: After you install the UltraPath software in the cluster environment, perform the following configurations: 1. Enable the cluster function. If you are to install UltraPath of the V100R002 version, manually enable the cluster function. If you are to install UltraPath of the V100R003 or V100R005 version, the system automatically enables the cluster function after installing the UltraPath software successfully. Note: The following operations are performed on in the Windows operating system. For details about UltraPath configuration in other operating systems, see the OceanStor UltraPath for XX User Guide. (XX is a specific operating system.) a. On the UltraPath for Windows Manager home page, click the Configuration tab. b. In the Cluster area, select Cluster Enable. c. Click Apply. 2. Set the Persistent Reversed Key (PRKey) of UltraPath to different values. The PRKey value is 00000101 by default. The first six digits from the left 000001 represent a cluster, and the remaining two digits 01 represent a node. Different nodes require different PRKey values. For example, in a dual-node cluster, if the primary node's PRKey value is 00000101 and the secondary node's PRKey value can be 00000102. a. On the UltraPath for Windows Manager main interface, click the Configuration tab. b. In the Persistent Reservation Key area under Cluster, enter different PRKey values. c. Click Apply.

Method used to configure DHCP client on the AR
The AR can function as a DHCP client to dynamically obtain configuration parameters such as an IP address from a DHCP server. This reduces the configuration costs and the errors and facilitates centralized management. Assume that RouterA functions as the DHCP client and RouterB as the DHCP server. The configuration is as follows: 1. Configure RouterA. [HUAWEI] dhcp enable //Enable the DHCP function. [HUAWEI] interface GigabitEthernet0/0/0 [HUAWEI-GigabitEthernet0/0/0] ip address dhcp-alloc //Enable the DHCP client on an interface. [HUAWEI-GigabitEthernet0/0/0] quit 2. Configure RouterB. [HUAWEI] dhcp enable //Enable the DHCP function. [HUAWEI] ip pool p1 [HUAWEI-ip-pool-p1] gateway-list 10.202.1.1 //Configure the gateway IP address. [HUAWEI-ip-pool-p1] network 10.202.1.0 mask 255.255.255.0 //Specify the range of IP addresses that can be dynamically allocated in the global address pool. [HUAWEI-ip-pool-p1] quit [HUAWEI] interface GigabitEthernet0/0/0 [HUAWEI-GigabitEthernet0/0/0] ip address 10.202.1.1 255.255.255.0 [HUAWEI-GigabitEthernet0/0/0] dhcp select global //Configure the global address pool mode. 3. Verify the configuration. Run the display ip interface brief command on RouterA to view the IP address that GE0/0/0 has obtained.
