        --xml-file (-x) <filename>      Retrieve XML from the named file

        --sync-call (-s)        wait for call to complete before returning

Note: the -x and -p options were added in 2.0.3.

Here is an example of adding a resource to the CIB:

cibadmin -C -o resources -X '<primitive id="WebServerIP" class="ocf" type="IPaddr" provider="heartbeat">
    <instance_attributes>
        <attributes>
            <nvpair id="WebServerIP_ip" name="ip" value="127.0.0.26"/>
        </attributes>
     </instance_attributes>
</primitive>'

Alternatively, you could put the XML into a file and do this:

cibadmin -C -o resources -x file.xml

One could then perform the following command to then add an extra parameter:

cibadmin -U -o resources -X '<primitive id="WebServerIP">
    <instance_attributes>
        <attributes>
            <nvpair id="WebServerIP_nic" name="nic" value="eth0"/>
        </attributes>
     </instance_attributes>
</primitive>'

Or, you could perform the same thing doing this:

cibadmin -R -o resources -X '<primitive id="WebServerIP" class="ocf" type="IPaddr" provider="heartbeat">
    <instance_attributes>
        <attributes>
            <nvpair id="WebServerIP_ip" name="ip" value="127.0.0.26"/>
            <nvpair id="WebServerIP_nic" name="nic" value="eth0"/>
        </attributes>
     </instance_attributes>
</primitive>'

To remove all instance_attributes:

cibadmin -D -o resources -X '<primitive id="WebServerIP">
    <instance_attributes/>
</primitive>'

Or, to remove the whole resource, one would run this:

cibadmin -D -o resources -X '<primitive id="WebServerIP"/>'
