I have an APC MasterSwitch as my fencing device. I configured my cluster to use "APC" as the fencing device, and have confirmed that it has the correct un, pw, and IP address configured. However, when it tries to reboot a failed node, I get this in /var/log/messages: Jul 20 15:51:28 server1 fenced[32169]: agent "fence_apc" reports: failed: unrecognised menu response Jul 20 15:51:28 server1 fenced[32169]: fence "server2.my.domain.com" failed However, when I run this command from a terminal, it runs fine and the failed node reboots: fence_apc -a 192.168.1.61 -l ***** -p ***** -n 6 -v This is in rhel5 APC Firmware: ======================================================================= Network Management Card AOS v2.6.4 MSP APP v2.6.2 ======================================================================= cluster.conf file: ======================================================================= <?xml version="1.0"?> <cluster alias="cluster1" config_version="20" name="cluster1"> <fence_daemon post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="server1.my.domain.com" nodeid="1" votes="1"> <fence> <method name="1"> <device name="APCMS62" port="7" switch="0"/> </method> </fence> </clusternode> <clusternode name="server2.my.domain.com" nodeid="2" votes="1"> <fence> <method name="1"> <device name="APCMS62" port="6" switch="0"/> </method> </fence> </clusternode> </clusternodes> <cman expected_votes="1" two_node="1"/> <fencedevices> <fencedevice agent="fence_apc" ipaddr="192.168.1.61" login="name" name="APCMS61" passwd="pass"/> <fencedevice agent="fence_apc" ipaddr="192.168.1.62" login="name" name="APCMS62" passwd="pass"/> </fencedevices> <rm> <failoverdomains> <failoverdomain name="main" ordered="0" restricted="0"> <failoverdomainnode name="server1.my.domain.com" priority="1"/> <failoverdomainnode name="server2.my.domain.com" priority="1"/> </failoverdomain> </failoverdomains> <resources> <smb name="smb1" workgroup="WKGRP"/> <ip address="192.168.1.20" monitor_link="1"/> </resources> <service autostart="1" domain="main" name="samba"> <smb ref="smb"/> <ip ref="192.168.1.20"/> </service> </rm> </cluster> ======================================================================= Confidentiality Notice: This message is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
