I have put together a STONITH script for the synaccess
(http://www.synaccess-net.com/remote_power_products.php?cat=1&id=all) devices. These devices have rs232, web, telnet and
SNMP based configuration controls. This script uses the user configured outlet name, to determine the host machine
plugged into that outlet. Stonith can then detect the controlled hosts and set their power states accordingly.
For example:
stonith -t external/synaccess synaccessip=192.245.184.102 community=public -T
on udt64-2
I have attached the script and pasted it below:
#!/bin/bash
