Figure 4.20, “RHEV-M REST API” shows the configuration screen for adding an RHEV-M REST API device
Figure 4.20. RHEV-M REST API
The following command creates a fence device instance for an RHEV-M REST API device:
ccs -f cluster.conf --addfencedev rhevmtest1 agent=fence_rhevm ipaddr=192.168.0.1 login=root passwd=password123 \ power_wait=60 ssl=on
The following is the
cluster.conf entry for the fence_rhevm device:
<fencedevices> <fencedevice agent="fence_rhevm" ipaddr="192.168.0.1" login="root" name="rhevmtest1" passwd="password123" \ power_wait="60" ssl="on"/> </fencedevices>
