Hi,

The problem got resolved.
 But I am not able to see ib in 'lctl list_nids' output
 My lnet.conf file entry is 'options lnet networks=o2ib(ib0)' This file is not executable.

 Can you help ?

Regards,
Parag

your lnet is probably not configured correctly. Things to check:
- is the ib0 device there (i.e. make sure the infiniband layer works
correctly)?
- does the ib0 haven an ip address? (lustre normally doesn't use ip over
ib but it uses the ip-addresses for identifying the hosts)
- verify that you can ping the ip (with normal network ping to ensure
that the connection is working)
- Is the lnet module loaded?
- if not can you load it manually with modprobe lnet?
- what is written to dmesg / syslog when it fails?
- when the module is loaded, try lctl network up
