It has come to a decision now to making the OS standalone for now as there is *not* much time to troubleshoot / correct the cluster configuration. Even removing the cluster fileset is not acceptable. Looking at the cluster resources and verify logs, which seemed to be running every midnight, it looks healthy (though I can't really say much as I have never seen the resource group working). All the while its a cluster without a substance having clcomd running and RG (meaning VG, FS mounted normally, apps started manually) and downtime not as generous. As much as possible, I want the cluster to be taken out completely if that will be the direction but even so, they can only give me a 5 minute window for a reboot.
My question lives wherein will below suffice in taking out the cluster service and no "dead man switch" or that can take over the system and have it just crash:
1.) Comment out / Take out cluster startups (harc.net, telinit, clcomd) from inittab
2.) Set the VGs to be varied on upon boot, filesystem be mounted automatically
3.) Putting the service IP as alias to one interface
4.) Reboot machine
Maybe until they can migrate to a new box with a more intensive tests done before rolling it out and see to it that failover testing needs to be done if need be and of course resource group failing over the way it should be. It may sound like a irresponsible move now but the uptime is more important as of this 5.2 setup. They *think* its a risk even starting the cluster thus a decision to making it standalone as that it functions currently all manual. Thanks.

xml::xpath::node
XPath::Node(3) User Contributed Perl Documentation XPath::Node(3)
NAME
XML::XPath::Node - internal representation of a node
API
The Node API aims to emulate DOM to some extent, however the API isn't quite compatible with DOM. This is to ease transition from XML::DOM
programming to XML::XPath. Compatibility with DOM may arise once XML::DOM gets namespace support.
new
Creates a new node. See the sub-classes for parameters to pass to new().
getNodeType
Returns one of ELEMENT_NODE, TEXT_NODE, COMMENT_NODE, ATTRIBUTE_NODE, PROCESSING_INSTRUCTION_NODE or NAMESPACE_NODE. UNKNOWN_NODE is
returned if the sub-class doesn't implement getNodeType - but that means something is broken! The constants are exported by default from
XML::XPath::Node. The constants have the same numeric value as the XML::DOM versions.
getParentNode
Returns the parent of this node, or undef if this is the root node. Note that the root node is the root node in terms of XPath - not the
root element node.
to_sax ( $handler | %handlers )
Generates sax calls to the handler or handlers. See the PerlSAX docs for details (not yet implemented correctly).
MORE INFO
See the sub-classes for the meaning of the rest of the API:

o XML::XPath::Node::Attribute
