DNS lookups
For successful failover cluster configuration, Milestone recommends that you run DNS queries in Windows PowerShell:
-
Use forward DNS lookup to obtain an IP address by searching the domain
-
Use reverse DNS lookup to obtain the host name that is related to an IP address
To make sure that the IP addresses and the host names of the nodes are resolved as expected, you must perform the queries on Node 1 and Node 2:
| Query name |
Command |
Perform on |
Expected result |
|---|---|---|---|
| Forward DNS lookup | Resolve-DnsName [Node 2 host name] | Node 1 | The host name of Node 2 corresponds to the first IP address on the list. |
| Forward DNS lookup | Resolve-DnsName [Node 1 host name] | Node 2 | The host name of Node 1 corresponds to the first IP address on the list. |
| Reverse DNS lookup | Resolve-DnsName [Node 2 IP address] | Node 1 | The IP address of Node 2 corresponds to the first host name on the list. |
| Reverse DNS lookup | Resolve-DnsName [Node 1 IP address] | Node 2 | The IP address of Node 1 corresponds to the first host name on the list. |
