Hi Dejan,

It is a description of rule in cib.xml.

OK.

It is assumed that there are two nodes.(hostname : node-a and node-b)
The user can write a node name in rule of cib.xml in capital letters.

-------------------------------------------------------------------------
      <rsc_location id="domU-xen1-node1" rsc="domU-xen1">
        <rule id="domU-xen1-node1-rule-1" score="200">
          <expression attribute="#uname" id="domU-xen1-node1-rule-1-expression-1" operation="eq"
value="NODEA"/>
        </rule>
      </rsc_location>
      <rsc_location id="domU-xen1-node2" rsc="domU-xen1">
        <rule id="domU-xen1-node2-rule-1" score="100">
          <expression attribute="#uname" id="domU-xen1-node2-rule-1-expression-1" operation="eq"
value="NODEB"/>
        </rule>
      </rsc_location>
-------------------------------------------------------------------------

Rule works definitely.

But, hostlist of stonith does not work definitely when I wrote it in capital letters.

-------------------------------------------------------------------------
      <primitive class="stonith" id="Stonith1" type="external/ibmrsa-telnet">
        <instance_attributes id="prmStonith1-2-instance_attributes">
          <nvpair id="prmStonith1-2-priority" name="priority" value="2"/>
          <nvpair id="prmStonith1-2-stonith-timeout" name="stonith-timeout" value="60s"/>
          <nvpair id="prmStonith1-2-ip_address" name="ip_address" value="192.168.18.115"/>
          <nvpair id="prmStonith1-2-nodename" name="nodename" value="NODEA"/>
(snip)
