You can get the current export policy name from "volume-get-iter" which will return something like this:
<attributes-list>
<volume-attributes>
<volume-export-attributes>
<policy>mike_test10</policy>
</volume-export-attributes>
</volume-attributes>
</attributes-list>
Along with a ton of other information.
If you want the details of the export, you'll need to call "export-rule-get-iter" with an option "policy-name", for example:
NaElement request = new NaElement("export-rule-get-iter");
request.addChildElem(new NaElement("max-records", "32768"));
NaElement query = new NaElement("query");
NaElement exportRuleInfo = new NaElement("export-rule-info");
exportRuleInfo.addChildElem(new NaElement("policy-name", policyName));
query.addChildElem(exportRuleInfo);
request.addChildElem(query);
NaElement response = server.invokeElem(request);
If you'd like to assign an export rule to a volume, you can create the policy with "export-policy-create" and assign it to the volume with "volume-modify-iter" with an option set to "volume-export-attributes". For example:
NaElement request = new NaElement("volume-modify-iter");
NaElement query = new NaElement("query");
NaElement attributes = new NaElement("attributes");
NaElement volIDAttributes = new NaElement("volume-id-attributes");
volIDAttributes.addNewChild("name", volume);
NaElement volAttributes = new NaElement("volume-attributes");
volAttributes.addChildElem(volIDAttributes);
query.addChildElem(volAttributes);
NaElement securityAttributes = new NaElement("volume-security-attributes");
securityAttributes.addNewChild("style", securityStyle);
NaElement volAttributes1 = new NaElement("volume-attributes");
NaElement exportAttributes = new NaElement("volume-export-attributes");
exportAttributes.addNewChild("policy", exportPolicy);
volAttributes1.addChildElem(exportAttributes);
volAttributes1.addChildElem(securityAttributes);
attributes.addChildElem(volAttributes1);
request.addChildElem(query);
request.addChildElem(attributes);
NaElement response = server.invokeElem(request);
