Method used to change the IP address of a cluster

0

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.

How does an AR reclaim IP addresses
You can manually reclaim IP addresses that cannot be released due to exceptions. The reclaimed IP addresses become idle and can be re-allocated to clients. The command is as follows: reset ip pool { interfacepool-name | nameip-pool-name } { start-ip-address [ end-ip-address ] | all | conflict | expired | used } Conflicting, expired, and used IP addresses can be reclaimed.
To reclaim the allocated IP address of 10.1.1.5 that has been bound to a MAC address, use the following method:
- For the global address pool
<Huawei> reset ip pool name pool1 used //Release the allocated IP address.
<Huawei> system-view   //If IP addresses are not bound to MAC addresses, you do not need to perform the following operations.
[Huawei] ip pool pool1
[Huawei-ip-pool-pool1] undo static-bind ip-address 10.1.1.5 //Remove the static binding.
- For the address pool:
<Huawei> reset ip pool interface vlanif100 used //Release the allocated IP address.
<Huawei> system-view   //If IP addresses are not bound to MAC addresses, you do not need to perform the following operations.
[Huawei] interface vlanif 100  
[Huawei-Vlanif100] undo dhcp server static-bind ip-address 10.1.1.5  //Remove the static binding.
Note: If a used IP address is within the IP address range specified by the command, performing the preceding operations may cause unexpected logout.
