Incorrect system_mode in the bare metal installation guide

[Pratik M.]

Brief Description
-----------------
I was trying to install R2.0 using:
https://docs.starlingx.io/deploy_install_guides/current/bare_metal_aio_duplex.html

Found a couple of issues:
1. Incorrect system_mode in the commands. It says:
cat <<EOF > localhost.yml
system_mode: standard
[...]

but "standard" seems to be unsupported and the playbook fails. Should be simplex, I guess

2. The guide talks about setting "ansible_become_pass" variable but the default template does not have the same.

Severity
--------
Minor

Appears to be a documentation issue; seems minor. Would be nice to fix and re-post for stx.2.0 if possible.

We are working on the documentation fix for #1 reported above.

Regarding the second reported issue for "ansible_become_pass" variable: Are you reporting that this is causing an issue for you? Or are you commenting that there is no corresponding "ansible_become_pass" value in the default configuration /usr/share/ansible/stx-ansible/playbooks/bootstrap/host_vars/default.yml?

[Pratik M. (pvmpublic)]

Thank you for taking a look. About #2: I meant the latter. There is no corresponding variable in the template.

RE: Incorrect system_mode in the commands. This was fixed with https://review.opendev.org/#/c/682967/. We'll address the reference to the default ansible template in a future review and then mark this bug as completed. Yes, this is retrofitted into R2 docs.
