Checking the Integrity of the Link

After you determine that the rdc service is ready, check the integrity of the TCP/IP link. As part of the installation process, you entered the primary and secondary host names and IP addresses of the machines where the software is installed in the /etc/hosts file. Make sure this file contains the same information on the primary and secondary hosts because the software is bidirectional. The software uses these hosts to transfer data.

Simple tests to check link integrity include the following:

■Use the telnet or rlogin commands to connect to the hosts.

■Use the ifconfig command to check your network interfaces.

■Use the ping command to make sure packets are being transmitted.

■Use the snoop or atmsnoop commands to make sure the software is copying data.

Note – The dsstat command displays volume information The sndradm -Hcommand displays link I/O statistics.
