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 -H
command displays link I/O statistics.
