Parameter Description
MethodName
A name describing the fencing method performed by the listed
devices. For example, a
MethodName
of
power
could be used
to describe a fencing method using an APC MasterSwitch. Or, a
MethodName
of
Cascade1
could be used to describe a
cascaded fencing method.
NodeName
The Linux hostname of the node.
Note : Make sure that you use the Linux hostname and that the
primary IP address of the node is associated with the hostname.
Specifying a
NodeName
other than the Linux hostname (for
example the interface name) can cause unpredictable results —
especially if the node is connected to multiple networks. To
determine the hostname of a node, you can use the
uname -n
command at the node. To verify the IP address associated with
the hostname, you can issue a
ping
command to the hostname.
PortNumber
For power and FC switches: The port number on the switch to
which this node is connected.
For HP RILOE: This is an optional value that defines a local port
to be used. The default value is 8888.
SwitchNumber
For use with APC MasterSwitch: When chaining more than one
switch, this parameter specifies the switch number of the port.
This entry is not required when only one switch is present. (The
default value is 1 if not specified.)
UserId
The user ID of the node to be fenced.
