DNS Redirection using the Update DNS Tool

Use this tool to change the DNS A record of the master server to resolve to the IP address of the replica. You use this tool after you start or stop the VM using the Start/Stop VM feature. This redirection is applicable when the master and replica are on the same or different subnets. You can use this tool by running the update_dns.exe file in the RHA engine installation folder.

Syntax:
Update_dns.exe -dns -hostname -hostip -ttl -username -password -keyfile

Example: Update the master server address, master.rha.com (199.100.5.1) to that of the DNS server (199.200.2.1).

Update_dns.exe -dns 199.100.5.1 -hostname master.rha.com -hostip 199.200.2.1 -username test -password test

Example: Update the local server address to that of DNS servers 199.100.4.1 and 199.100.6.1.

Update_dns.exe -dns 199.100.4.1,199.100.6.1
