Bug 579859

Opened SR 2014406 to track this request.

*** Bug 591238 has been marked as a duplicate of this bug. ***

Hi Scott, I've had a heck of a time trying to find someone within Cisco that can help assist test/verify this. Would you happen to know who I can start with to find the right person?

I can help tee you up with someone who can work with the XML API on this.  This
is definitely something that would benefit us mutually.  Please e-mail me, we
can coordinate a resource, and then add them to the BZ for further updates.

Andrius / Stuart:

I would be the resource that can help test / verify this.

Eric, we need a simulator of some sort to develop this.  Lon H said he talked to you about getting one.  Right now we're blocked on this, and with the code freeze date imminent for RHEL5.6 this may need to get pushed to 5.7

Perry:

I can get one to you today.  Would you like me to put it out on my Dropbox account and send you a public link?  Or would you like me to upload it to a ftp server you have?

Let me know either way.  I can help you out with this no problem.

Thanks,
Eric

Dropbox would work.  The developer who'd be working on this is out for a week or so anyhow, so we're sort of stuck for the short term anyhow.  But if he can hit the ground running with the simulator from your Dropbox link when he gets back, that would be good.  Thanks!

OK.  I'll upload it later today.  I'll post the link here when it is done.

Thanks,
Eric

Here is the download information for the UCS Platform Emulator.

http://dl.dropbox.com/u/5820028/Cisco_UCS_Platform_Emulator_v1.3.55965.355989.zip

@Eric:

Thanks for emulator. 

Is there a possibility to send several commands through one open connection? e.g. login, get status of machine, power off, ..., logout

Proposed fence agent

You will need this fence agent + fence library (attached as next file) and curl. 

Agent was tested against emulator where user/pass identification is not working, so I was unable to test it. It works for operations status/on/off/reboot. 

Missing features: 
* timeout options
* print debug to file
* it is questionable if we should use curl or implement it by ourselves.

Fencing library

SSL version is not working correctly for me - no response for login

how to use it:

./fence_ucs.py -a 192.168.192.128 -l config -p config -o status -n aqua_ri-us

Yes you can send several commands through one open connection.  Once you do the login command, you can query for power status, power machines on / off, query again for power status, etc. and then logoff.  

Best practices do say to reuse a session as much as possible, but do logout when finished so that session is deleted.  If you have questions, please feel free to call me if you want to talk in real time.

Thanks,
Eric

We will need to test SSL version on a real system.  HTTPS XMLAPI communication is not supported in our emulator just yet.  Looking to do that in the next rev of our emulator.

Eric,

Can you please test the entire fence_agent on a real system as soon as we have it available for you and let us know the results?

Thanks
Sayan

Sayan:

yes I can do that no problem.  I'm out in San Francisco at VMworld until Thursday night.  Earliest I can do a full blown test is on Friday.  Just send me the test plan you would like done, and I can test it against my systems in the lab.

Proposed fence agent

New version of fence agent. It do not use curl but pycurl. 

Each command is issued in new connection (cookie is reused) as it will be more portable for other fence agents if needed. This version was tested against real machine (list, status, reboot, on, off) and it works as expected.

Timeouts, better error handling still have to be added. There will be some rewriting after fence agent for RHEV will be ready as they surely will have common code.
