This is using SUSE Linux Enterprise server 11 SP1. After setting the IP on the NIC, I found that there are 127.0.0.2 record created in /etc/hosts. Does this is needed? As pinging from other machine failed. What would be the best way to tackle this issue?

Pinging from different machine. Check the firewall of your system then disable it and also check whether you have configured network settings correctly.

for 127.0.0.2 please follow the URL.

any address withtin 127/8 netblock is a 'localhost' address and is not reachable from outside.  I think you should leave it alone.

127.x.x.x addresses are all local. 127.0.0.2 is a loopback device for second NIC.

This is a work arround i found at Novel where somebody was facing issue due this second loopback address. If you face any issue you can try the same as well.

Anyways there is no harm to remove that second loopback address as well.
