To create the
nodes.ccs
1. Create a file named
a. If you are configuring a node for one fencing method (not cascaded), specify only one
fencing method per node in the
method as follows. Refer to Table 6-3 for syntax description.
APC MasterSwitch — For a node with a single power supply, refer to Figure 6-13. For

a node with dual power supplies, refer to Figure 6-14.
WTI NPS — Refer to Figure 6-15.
•
Brocade, McData, or Vixel FC switch — Refer to Figure 6-16.
•
GNBD — Refer to Figure 6-17.
•
HP RILOE — Refer to Figure 6-18.
•
xCAT — Refer to Figure 6-19.
•
Egenera BladeFrame — Refer to Figure 6-20.

Warning
Manual fencing should not be used in a production environment. Manual fencing de-
pends on human intervention whenever a node needs recovery. Cluster operation is
halted during the intervention.
b. If you are configuring a node for cascaded fencing, use the file format in Figure 6-22.
Refer to Table 6-3 for syntax description.
Note
Figure 6-22 does not show device-specific parameters for fencing methods. To determine
device-specific parameters, refer to the appropriate figures listed in Step 1, part a.
2. For each node, specify NodeName, IFName, and the IP address of the node name,
IPAddress.
If your cluster is running Red Hat GFS 6.0 for Red Hat Enterprise Linux 3 Update 5 and later,
you can use the optional
