Matsushima-san Thank you very much for your reply. And sorry for late reply.
>Do you get same result by executing the command manually with different parameters like this? I tried following command but same result (1sec interval) [command used to send unsolicited arp] /usr/libexec/heartbeat/send_arp -i 1500 -r 8 eth0 192.168.12.215 auto not_used not_used [result of tcudump] 04:31:50.475928 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:51.476053 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:52.476146 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:53.476246 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:54.476287 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:55.476406 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:56.476448 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 04:31:57.476572 ARP, Request who-has 192.168.12.215 (Broadcast) tell 192.168.12.215, length 28 >Please also make sure the PID file has been created properly. When I checked manually with send_arp command, I didn't use send_arp command with "-p" option. Even when I did fail-over of IPaddr2resource (not manually execute send_arp command), I couldn't see pid file generated at /var/run/resource-agents/. I used following command to see if pid file generated. watch -n0.1 "ls -la /var/run/resource-agents/" Thank you in advance.
