2.1 Error with Create Volume cmd: '_x001B_', hexadecimal value 0x1B, is an invalid character

Hi,

I recently upgraded to 2.1 and ran a workflow using the Create Volume cmd in my test environment and got the following error message: "'_x001B_', hexadecimal value 0x1B, is an invalid character. Line 1, position 113."

Running the same workflow on a different array will run successfully but I'm just curious about the error condition in case it will appear in my production environment. Command log is as follows (I removed the names of my systems):

09:24:46.532 INFO  [null] ***** Workflow Execution Started *****

Any help would be appreciated.

Hey Tim,

Do the credentials for the array have any special characters in it? I've found some values are not escaped properly, including fairly basic characters like $ as a first character. Try changing the admin credentials for the array to alpha-numeric only and see if it helps. (and setting the new credentials in the credentials tab). Or create a second admin user with a simpler password to test if that's the problem.

The 0x1B is the Escape character so I'm assuming that's not actually in the credentials its trying to use. If it got past the credentials step I would expect to see a log for "Creating a new volume.....", so assuming the volume didn't get created and the failure is for options setting.

Regards,

- Michael.

Thanks Michael, using a different account with a less complex password has done the trick.

Hey Tim,

Can you tell me the version of ONTAP you are running and whether it is C-mode or 7-mode?

Hey Anil,

For me it was 7-mode that caused the password issues with special characters, it's the connect to server itself that causes it. C-mode seemed to be okay with the ones I tried it with.

Thanks M,

One more question. Did you try connecting to different 7-mode filers. Did it fail to connect in every instance where the password contained special characters?

Hi Anil,

Yep, it failed on multiple instances, however I did only test on simulators.

Thanks Michael,

There doesn't seem to be a problem with physical filers. I will try on simulators too. What version of ontap were you running on the simulators?

If you still have the sims with you, can you share it?

I am trying to fix this.

Regards,

Anil

Hi Michael,

Can you share the the version of ONTAP you tried this on?

Hi Anil,

The OnTap version is 8.2. It is fixed in WFA 2.1 it seems. Try a password like "$torage", it could be the $ thats cause it in this case, and I believe the other tests had a $ in the password too.

Unfortunately I don't have any more 7-mode sim's to test the other characters anymore.

Michael,

Was there a burt that was raised to fix this in WFA 2.0?

I just got the same error and was scratching my head until reading this post.

 

What had happened was that I'd restored WFA from a database backup (of another WFA box), and it seems like the credentials don't get restored (this was for connecting to Clustered ONTAP.)

 

Once I re-entered my Cluster login, all was dandy again Smiley Happy
