Odd error from vCenter acquisition

I've recently begun getting an odd error with each attempt to acquire my vCenter. I'm happy to go log-diving for the reasons, I'm just not sure where to go look. Here's the error I'm seeing.

Cannot convert value "á" to type "System.Byte". Error: "Value was either too large or too small for an unsigned byte."

Looking for suggestions for chasing this down.

Re: Odd error from vCenter acquisition

This is interesting Phil. This is coming due to this á  which is a Unicode Character. Do you have any VM with names using this character or Non English OS version?

Can you help by answering the following questions.

1. Its looks like the same VC acquisition was working fine before and then started to fail with this error. Is this Correct?

2. Your WFA version and VC version?

3. Is the language for the VC en-US ( default )?

  • 1.  On your WFA server just run the acquisition once. Let it fail with the same error.
  • 2.  On your WFA server, Go to the location WFA\jboss\standalone\tmp\wfa and send me the following files.
  • 3.  Host.csv
  • 4.  Data_Store.csv
  • 5.  Lun.csv
  • 6.  Virtual_Machine.csv
  • 7.  Virtual_Disk.csv
  • 8.  Nas_Share.csv

Send the Autosupport file and the above files to me at: sinhaa at netapp dot com

I'll look at them and get back to you.

Re: Odd error from vCenter acquisition

sinhaa,

I had some virtual machines with "βeta" as part of the display name shown in vCenter - not the actual machine name. I have changed those to "beta" and it made no difference. I will get you the files.

Re: Odd error from vCenter acquisition

Francois/Phil,

     Please find the attached posh script, save it in your WFA server. Open powershell ISE or any editor and at the beginning of the script, modify the the VC_ip, username, password fields according to your setup.

Execute it. Kindly send entire error message to me at : sinhaa at netapp dot com.

Also mention your Poweshell and .NET version

warm regards,

sinhaa

Re: Odd error from vCenter acquisition

Francois,

     I'm working on this problem and I think this problem comes when your VC has one or more objects ( VMs, Vdisks etc.) with names in non-english alphabets. The error message may not be able to display this exactly.

I think I have a solution for it, but its still under test. It worked fine in my environment, so can you too try to see if it's working okay for you too. It will be of big help to me in fixing this.

1. Clone the Datasource Type VMWare vCenter and name it like VMWare vCenter 2

2. Select Scheme : vc

3. In the Powershell code block, enter the code which is there in the attached file. No modifications needed.

4. Add a Datasource of the Type: VMWare vCenter 2  and provide the credentials etc.

5. Acquire it as you normally would do.

Let me know if this worked for you.

Re: Odd error from vCenter acquisition

Responded to Abhishek with the information offline, reposting here for general information.

As mentioned above, I had a VM where the name of the VM - actual name in the file system - included "βeta" as part of the file name. This was causing the datasource to fail to acquire.

My fix was to 1) power down and unregister the VM, 2) rename the files using "beta" in place of "βeta", 3) edit and update the VM config files to point to the corrected file names, 4) import the VM back into vCenter.

I should point out that as soon as I unregistered the VM, acquisition began running successfully.

Re: Odd error from vCenter acquisition

I attempted Sinhaa's VC fix.   The discovery definately ran longer, but resulted in a different error message.

@sinhaa is there newer code for the vCenter discovery?  Let me know if you want any log files / etc.

@ChadPruden

 

Clone the VC data source type and replace the code with the one in this attachment.

 

Let me know if this worked for you.
