ibmrsa-telnet - External stonith plugin for HAv2 (http://linux-ha.org/wiki) Connects to IBM RSA Board via telnet and switches power of server appropriately. Description: IBM offers Remote Supervisor Adapters II for several servers. These RSA boards can be accessed in different ways. One of that is via telnet. Once logged in you can use 'help' to show all available commands. With 'power' you can reset, power on and off the controlled server. This command is used in combination with python's standard library 'telnetlib' to do it automatically. Code snippet for cib It's useful to give a location preference so that the stonith agent is run on the/an other node. This is not necessary as one node can kill itself via RSA Board. But: If this node becomes crazy my experiences showed that the node is not able to shoot itself anymore properly. You have to adjust parameters, scores and timeout values to fit your HA environment.
