Error message "Guest Operation Agent Couldn’t be Contacted" during creating a temporary directory in guest vm

[koushik_vmware]

Hello,

I would like to create a temporary directory in the vm by using the inbuilt vCenter (version : 6.0.2 ) plug-in library workflow "Create temporary directory in guest" in vRO 7.0.

But during execution of this Workflow, I received the error message “Guest Operation Agent Couldn’t be Contacted”.  As the error it seems that there is some issue with vmtools in that vm.S

Can you please help me out how to resolve this issue ? Thanks for your help.

Thanks,

Koushik

Hi,

This error could happen if the user you are using is not connected to the machine and hence there is no open session.

Try adding the following line on line 7 in the workflow (after setting username/password properties on guestAuth object)

guestAuth.interactiveSession = false;

Hello Illian,

Thanks for your suggestion. I have already tried with this one. And now I am getting an error "A specified parameter was not correct".

Below is the code. It seems that the error happened during calling the "createTemporaryDirectoryInGuest" function. (marked in red colour).

I am not sure why this error happened. Can you please help me out ?

Thanks,

Could you provide the full error message log + values of the input parameters?

Hmm, I'm out of ideas why it doesn't work. The parameters seem correct. I tried the same workflow in my environment and it worked as expected.

I'd suggest to check vCenter logs for more information (eg. which parameter is not correct).

[koushik_vmware]

Dear,

Thanks, Can you please provide me the name of the vCenter logs/ which logs I need to check ?

Thanks,

Koushik

Hello,

I captured the log from hostd.log file and found the error there also. Below are the traces.

But I am not much sure about the error. Can you please check and help me out.

Thanks,

Hello Ilian,

Did you get any clue ? Please let me know if you find anything more ?

Thanks,

oh, that points towards you still having double \\ backslash in the string that is send to vmware tools.

So just try to replace with a forward slash / , it should even work on windows. Or play around with the different escaping strategies in javascript (or wherever the string containing the path name originates from.)… yes, might be some trial and error 😉

Dear,

I tried with all options but still have no luck.

Is this issue related to others like 'storage' linked to vm ?

Thanks,

koushik

[tschoergez]

can you try to run the logic completely without the vmDir parameter of the createTemporaryDirectoryInGuest() method?

this will create the directory in the default temp directory of the Guest OS (I think that's %TEMP% in windows, /tmp in linux).

So we can rule out problems with the pathname...

[koushik_vmware]

tried with blank value in vmdir parameter but still got the same error.

Thanks,

koushik

[koushik_vmware]

Hello,

Is there any more clue ? I am having the same issue still now.

Thanks,

Koushik

[tschoergez]

so what's the exact error message when you try without vmdir parameter?

[qc4vmware]

Did you verify that from an rdp session you can login with the administrator account?

[koushik_vmware]

Dear,

I am getting an error "A specified parameter was not correct" even I executed the WF without any value in vmdir parameter.

Thanks,

Koushik

[koushik_vmware]

Dear,

Yes, I have verified that it is successfully logged in to the guest machine/vm with administrator account via RDP session.

In case there is an issue with credentials then it will throw un-authentication error. But here is it throwing another error which is very disappointing to me.

Any more clue ?

Thanks,

Koushik

[koushik_vmware]

Thanks Everyone. I resolved the issue related to error “A specified parameter was not correct” .

The root cause of this issue was passing the value of the parameter - ‘vmUsername’ in wrong format.

The correct format is : (administrator) not (.\administrator).

Thanks,

Koushik
