[Linux-cluster] [Linux-HA] Problems with fence_apc agent and accessing APC AP8965

[Marek Grac]

Hi,

This is a problem of firmware support, APC have completely changed 
text-based interface (and it is better than before). This should be 
solved in release fence-agents-3.1.5-35.el6 (RHEL 6.5). If that (or 
upstream 4.x version) is not working please create a bugzilla report.
