PureStorage Flash Blade Discovery

[Gus1]

We've been working on configuring FlashBlade discovery by following the documentation presented here:
https://docs.servicenow.com/bundle/washingtondc-it-operations-management/page/product/service-mappin...

We've confirmed that we are meeting the prerequisites and that the FlashBlade is on version 4.
We've configured the SSH credential and the applicative credentials. 
We've opened ports 22 and 443 for this. 

It seems the way this should work is the shazzam probe will identify port 22 is open and kick off the unix classify multiprobe, this multiprobe has 7 child probes one of which is the PureBlade probe. The PureBlade probe has a probe parameter that contains a shell script, the shell script out of box is the following:

#!/bin/sh
echo `pureblade list 2>&1`

The other parameter we have is the allow_unsupported_shells and we've set this to "true". 

This probe is supposed to run this shell script from the parameter above and help identify the FlashBlade, with the PureBladeByName unix classification which launches the pattern for FlashBlade Pure Storage. 

The problem we're having is the FlashBlade is unable to run echo shell command. Discovery logs show this error:

The `pureman` command displays information about the Purity//FB CLI. To display
CLI syntax and usage guidelines, run `pureman pureman`. To display information
about a Purity//FB CLI command, run the `pureman` command with the Purity//FB
CLI command name. For example, run `pureman purefs` to display the man page for
the `purefs` command.

Error: Arguments may not contain line breaks
Error: Unknown command - #!/bin/sh

Error: Unknown command - echo

Error: Unknown command - }

Error: Unknown command - snc_func_1 - Exit status: 127

We've spoken with the Pure vendor a couple of times and they've pushed back on running echo on FlashBlades, they've stated that isn't something they support. Does anyone have any other suggestions or has anyone been able to resolve a similar issue before?

Having almost the exact same issue but not seeing "Error: Unknown command - #!/bin/sh". Did you get anywhere with this so far?

HI is asking me to contact the Pure Vendor again since the error is with their shell but I threw the question on Slack and they advised working the HI again because of the following:
"Yeah there is a HI KB article for the need to enable a non bourne shell and it doesn't work. Which means there pattern doesn't work as they said it should so they need to actively work with you on it."
I'm also at this point trying to get both vendors to talk it out as the process is broken from what I can tell, I'm trying to schedule a meeting with them both.

Thanks for this, that is helpful to know. If I get any further I'll update here but sounds like we are going to hit the same issue so useful to know we're not alone.

I'm currently having the same issue, so of course I'm going to say to please post the resolution when you get one.  Thanks!
