Prerequisites for configuring Resiliency Platform components
Before configuring the component through product bootstrap, make sure that following prerequisites are met:
Veritas Resiliency Platform now supports Internet protocol version 6 (IPv6) along with Internet protocol version 4 (IPv4) .
Before you use the hostname and the IP address in the Network settings, you need to register them with the DNS server. Also ensure that the reverse lookup for that IP address works.
Ensure that the host name corresponding to the IP address is less than 64 characters long. In case of NAT, this is required for host names corresponding to both private and public IP addresses.
If you plan to use the DHCP server, the DHCP server should be reachable from the subnet and should be able to respond to the subnet where you plan to deploy the product. This requirement is also applicable to static DHCP.
To use DHCP network, you need to reserve an IPv4 address for the virtual appliance in the DHCP server along with the corresponding MAC address. You cannot configure IPv6 address for the virtual appliance in the DHCP server. See About IPv6 network support in Resiliency Platform.
If you are configuring multiple NICs using DHCP, ensure that same DNS is used to resolve the IP addresses for all NICs.
In case of multiple Resiliency Managers, you need to either use the same NTP server for configuration or ensure that the NTP servers are properly synchronized.
Veritas Resiliency Platform supports Linux NTP server. You can also use a public NTP server If there is internet access to the appliance. It is recommended to use a pool (with odd numbers) of time resources for your NTP server. NTP server takes inputs from the available time sources and uses algorithms to find out the correct time. If there are even number of sources and they do not agree, then the algorithm of NTP server fails to make the right decision. Also, it is a better practice to use diversity of reference clocks. You can now configure NTP server using IPv4 or IPv6 address.
Ensure that the NICs of the virtual appliances have a static MAC address. You can set a static MAC address for the appliance NICs using the virtual machine settings.
While configuring the virtual appliances on the source data center, ensure that the IP and hostname of Resiliency Manager, IMS, and Replication Gateway can be resolved from the target data center and vice versa.
In case of a Replication Gateway, make sure to attach an extra disk of at least 50 GB before configuring the Replication Gateway.
