VNX XML API bug when querying Tree Quotas?

Question

Hi,

I'm using XML API on VNX VG2 to list the filesystem tree quotas:

When the tree quota soft limit is empty (NoLimit) it the XML API gives this error:

                The XML API server took an unexpected exception. This does not mean that it stopped functioning for other users. (In most casses it is an APL reply unmarshalling error).
                If the problem persists, collect support materials by running the /nas/tools/collect_support_materials script or the newer /nas/tools/automaticcollection script. Note any symptoms. If you require more information on the materials collection process, refer to the Problem Resolution Roadmap for Celerra, available on EMC Powerlink, or EMC Knowledgebase Support Solution number emc135846.

For more information, use the text from the error message's brief description or the message's ID to search the Knowledgebase on Powerlink. After logging in to Powerlink, go to Support > Knowledgebase Search > Support Solutions Search.

Exception tag: 14444c9febd
Exception message: For input string: "NoLimit"

But when I specify the tree quota soft limit (for example =0), then I get a correct response from the API.

Is this a known bug or feature or am I doing something wrong ?

Hi,

looks like you have indeed found a bug.

Please open a service request and post the SR number here.

You can refer to this post in the SR

Customer service then needs to open a bug – I can provide them the details to get started

You will notice that this error goes away after a day (nightly C3 cache refresh) or when you manually refresh the C3 cache

Thanks, I've created an SR. After this night it still doesn't work... How to manually refresh the C3 cache ? Do you know if this is a VNX VG2 specific bug ?

Rainer_EMC · Answer

Hi,

what is your SR number ?

To refresh the Cache see /celerra/commoncache/bin/c3refresh

Its run by default every morning a 1am

Or use the button in UniSphere called “Invalidate Cache and Refresh”

no it shouldn’t be VG2 specific

Thanks You should be hearing from support soon Out of curiosity – what you doing with the XML API – are you writing your own application ? Rainer

any updates ??

Hi,

that's what I got: Engineering has identified the bug which is causing your issue, and Development is working on a fix.

No estimated date when this will be done.

I'm writing an application to calculate the provided and used storage to our customers and to charge them.

I'm doing a POC now with bash and simple wget queries. Using XSL to transform the xml documents to the required output.

If everything works as expected I plan to do a perl script.

The API is very good I think and the documentation also, so far no problems regarding this.

I also tried to do some monitoring queries to get the alerts that can be viewed from the UnisphereGUI, but failed to filter the required information from all the alerts and logs that this API outputs.

Thanks For my curiosity – what programming language are you using ? Any feedback on the API so far (beside that bug) ?
