This is my test code.

        HttpHeaders head = new HttpHeaders();
        head.add("Content-Type", contentType);
        head.add("X-API-Session", this.getSession());
        head.add("Accept", "*/*");
        HttpEntity<String> requestEntity = new HttpEntity<>(head);
        return this.getRest().exchange(url, HttpMethod.GET, requestEntity, clazz);
    }

        String xml = getByContetType(url, String.class, "application/vnd.ibm.powervm.uom+xml;type=VirtualIOServer",args).getBody();

JSONObject r=session.getFullPathxml("https://10.20.32.90:12443/rest/api/uom/ManagedSystem/e41dbc2b-2389-3c45-9fea-4c8e109b06b2/LogicalPartition");
        AP.testPrintLpar(r);
        String link="https://10.20.32.90:12443/rest/api/uom/VirtualIOServer";
        JSONObject j=session.viosServer(link);
//        
        System.err.println(j);

result:

why  /rest/api/uom/VirtualIOServer return null?

Hi, 

The message you are seeing in the FFDC can be ignored. Though it is marked Error, it is just some debug statements. Thanks!

Hi,

It is not clear to me on the operation you are trying to perform using the test program. Is that to get the VirtualIOServer under specific System?

The URI /rest/api/uom/VirtualIOServer will return all the VIOSs across systems managed by the HMC.

The URI /rest/api/uom/ManagedSystem/{UUID}/VirtualIOServer will return VIOSs info from the specific system.

Since you mentioned that the URI did not return VIOS info, it could be possible that the URI would have resulted in error. Could you please run the URI in browser and ensure that it returned the response? Please ensure that the http code is 200 for the successful URI execution.

You could also use /rest/api/uom/VirtualIOServer/quick/All to list the quick response of the VIOSs. This will have minimal information in Json format. Thanks!

Hi,

I am surprised to see that you are getting 404 error for the quick call. But from the response looks like you are having HMC 820 or 830 level.

And from the second REST response, the call is returned with http-204. Which means there is no VIOS in the HMC. Just wanted to check with you if the HMC in question is managing any VIOSs? Could you please validate that with the HMC command line. You will have to use "lssyscfg -r lpar -m <CEC name> -Fname,state,lpar_env" to check that. The lpar_env will be "vioserver".

If the HMC is managing the VIOSs then it could be a some issue in HMC. We will need logs to debug the issue. You might need to open a PMR for it. One suggestion : Is it possible for you to update the HMC to latest level (current GAed version of the HMC is 860 and Service Pack1). Thanks!

thank you very much.

i tried refer to this website, http://www-01.ibm.com/support/docview.wss?uid=nas8N1018878 .

The problem should be out of hmc deploy.i will redeploy a new hmc.

i will use ssh to manage it.

Thanks.

Yes, the link you mentioned should be used for collecting the HMC logs.

Please let us know if you still see the issue even after updating the HMC. Thanks!
