5.On GRF 400, check /etc/grifconfig.conf for the following entry (or one similar):

gt020 192.168.13.129 255.255.255.128

gt030 192.168.13.4 255.255.255.128

6.On the CWS of SP2, check if SP Switch Router Adapter cards are configured. See if both SP Switch Router Adapter cards show up green in perspectives or enter SDRGetObjects switch_responds. Use Eunfence if needed.

7.Issue some ping commands to check the connection:

On node 11, node 12 and node 15 of SP2, ping the SP Switch interface of any node in partition 1 in SP2, for example:

root@sp2n11:/ ping 192.168.13.1

PING 192.168.13.1: (192.168.13.1): 56 data bytes

64 bytes from 192.168.13.1: icmp_seq=0 ttl=254 time=0 ms

64 bytes from 192.168.13.1: icmp_seq=1 ttl=254 time=0 ms ^C

----192.168.13.1 PING Statistics----

2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 0/0/0 ms

On any node in partition 1 in SP2, ping the SP Switch interfaces of any node in partition 2 in SP2, for example:
