To dynamically change the host’s management IPs, you can use the management-ips resource editing command.
For example: To change the management IPs onhost-id 0, run the following commands:
weka cluster host management-ips 192.168.1.10 192.168.1.20 weka cluster host apply 0
Note: The number of management IPs determines whether the host will use Highly Available Networking mode (HA), causing each IO process to use both hosts NICs. A host with 2 IPs will use HA mode and a host with only 1 IP will not use HA mode. It is also possible to define up to 4 IPs, in case the cluster is using both Infiniband and Ethernet network technologies.
