[ClusterLabs Developers] [ClusterLabs] Issue in fence_ilo4 with IPv6 ILO IPs

[Denis Medvedev]

I suppose something like this:  https://serverfault.com/questions/548777/how-to-prevent-delays-associated-with-ipv6-aaaa-records  
Probably your ILO prefer ipv4 addresses over ipv6 and trying to resolve name as ipv4 before trying to resolve via ipv6.
Try putting numeric values instead of names in ILOs.
