Configuring network settings for Resiliency Manager
A Resiliency Manager needs to communicate with multiple entities within Veritas Resiliency Platform such as the IMS and another Resiliency Manager in the domain. To facilitate separate communication channels for these communications, Resiliency Platform 10.4 extends support for configuring Resiliency Manager with three Network Interface Cards (NIC).
The Resiliency Manager appliance is shipped with three NICs. You can configure these NICs to be used for the following three communications:
For communication with Infrastructure Management Server (IMS)
For communication with other Resiliency Managers and clouds too
For communication with Product User Interface
If you do not plan to use three separate networks, you do not need to configure three NICs. You can configure one or multiple NICs based on your network layout. So, if you have only one network, you can configure only one NIC and associate all communications to go through the configured NIC.
Since IPv6 network support is provided from Resiliency Platform 3.3.1 version, you can configure the NICs using IPv4 and IPv6 addresses. For more information,See About IPv6 network support in Resiliency Platform.
Note:
The network configuration of the NICs performed during the bootstrap is final and you cannot edit the network configuration of the NICs at a later point of time.
To configure network settings for Resiliency Manager
- In the Host Network Settings section, the bootstrap program first checks for network configuration of all the NICs of the appliance and prints the network details of all the NICs. You are prompted to continue the process of bootstrap. You can see a list of sections that need to be completed as a part of host network settings:
Host Network Settings for communication with Infrastructure Management Server
Host Network Settings for communication to other Resiliency Managers
Host Network Settings for communication with Product User Interface
- For each section listed above, do the following:
Enter the NIC to be used for the communication. The name and MAC address of NIC is displayed.
The Bootstrap process checks if the NIC is already configured.
If the NIC is already configured then the NIC network configuration details are printed and you are prompted to confirm if you want to continue with the printed configuration.
If the NIC is not configured or if you do not want to use the existing NIC configuration, then you can choose to use either DHCP protocol or static protocol. In case of static protocol, you need to provide static network details such as IP address, prefix length.
Note:
Ensure that appropriate subnet or virtual switch is assigned to the network adapter. Confirm this by matching the MAC address shown in the bootstrap with the one assigned to the virtual machine by the virtualization or cloud technology.
Confirm if you want to add a static route. You need to set a static route for the interface only If you want the interface to reach a subnet that is different from all the subnets configured on this appliance and the default gateway is unable to communicate with that subnet. In this case, provide the subnet details (in CIDR format) at the input prompt. You can also set a static route to a host. In this case, provide the IP address of the host at the input prompt.
Confirm if you are in Network Address Translation (NAT) environment and want to configure NAT when the NICs are configured in IPv4 networks only.
Note:
Since NAT is not supported for IPv6 address, hence when you configure the virtual appliance using IPv6 address only and both IPv4 and IPv6 address, you are not asked about the NAT configuration. To know more about NAT support in Resiliency Platform
See About NAT support in Veritas Resiliency Platform. See About IPv6 network support in Resiliency Platform.
You can add NAT gateway for communication between multiple Resiliency Managers, only if all the Resiliency Managers are not deployed in the same data center.
- After successful configuration of the first NIC, confirm if you want to use the same NIC for the other communication channel. If you do not want to use the same NIC, perform step 2 for the other two communication channels.
Note:
You can select one or more NICs for communication with Product User Interface. If you want to use multiple NICs to access product user interface, enter space separated values of the NICs.
- Enter details for default router and then enter the DNS server details.
- The details of Host Network Settings are displayed and you are prompted to confirm. Review the information. If any information is incorrect, choose n to go back to the networking inputs page and correct the details. Upon confirmation, the network is configured.
