An updated fence-agents package that fixes a bug is now available for Red Hat Enterprise Linux 6.
Red Hat fence agents are a collection of scripts to handle remote power management for several devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.
A bug fix for a previous advisory, the RHEA-2010:0904 enhancement update, stated that the Brocade 200E, Brocade 300, Brocade 4100, Brocade 4900, and Brocade 5100 fencing devices are now supported by the fence_brocade agent. However, the fence_brocade agent was not included in the updated package. This update corrects this error, and the fence_brocade agent is now included in the package as expected.
All users of fence-agents are advised to upgrade to this updated package, which resolves this issue.
