Gave up on fence_vmware_ng, because it turns out that the fence_vmware supplied with cman-2.0.115-34 does work. That was disguised by what turned out to be a bug in VI Perl Toolkit. Since I got no hits on Google when I looked for this, I'm putting this here for the archive, and anyone else who happens to search... | $sudo fence_vmware -a virtualcenter -l [username] -p [password] -o reboot -n [node] | fence_vmware_helper returned Undefined subroutine &Opts::add_options called at /sbin/fence_vmware_helper line 82. Find VMware/VIRuntime.pm and add this line: | *** 13,18 **** | --- 13,19 ---- | | package VMware::VIRuntime; | | + use VMware::VILib; | use VMware::VIM2Runtime; | use VMware::VIM2Stub; Now it works. -- Cos -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
