Description

A couple of fence agents for Red Hat Cluster.

All listed models do not correctly handle concurrent connections. To avoid a mutual fencing, we add a little delay to each fence call: every node involved will sleep for (node_id - 1)*5 seconds. So, for example, node with id 3 will wait for 15 seconds and node with id 1 will not wait at all.

Currently supported models:

Aviosys IP9258 (fence_ip9258)
