Figure 4.23, “WTI Fencing” shows the configuration screen for adding a WTI fence device
Figure 4.23. WTI Fencing
The following command creates a fence device instance for a WTI fence device:
ccs -f cluster.conf --addfencedev wtipwrsw1 agent=fence_wti cmd_prompt=VMR> login=root passwd=password123 \ power_wait=60
The following is the
cluster.conf entry for the fence_wti device:
<fencedevices> <fencedevice agent="fence_wti" cmd_prompt="VMR>" ipaddr="192.168.0.1" login="root" name="wtipwrsw1" \ passwd="password123" power_wait="60"/> </fencedevices>
