Removing High Availability on 3850 Stack

[telecomjedi]

I am cleaning up my colleagues mess on a stack of 3850's. Apparently he had an issue with a stack member and removed/replaced it. In doing so the stack somehow entered SSO mode and also showed a foreign MAC issue. I was able to resolve the foreign MAC but am searching to get the stack out of HA/SSO mode. The version of the IOS is 3.6.7b.E.

If you are not stacking them, SSO mode does not do anything as there is only one switch.

I am seeking to have them out of SSO mode and acting as a stack.

What you are looking at deals with the control plane and not stacking.

Do a "show switch detail" and post results

Whatever the "issue" is, I'd avoid using 3.6.7b. The last "digit" is "7b". The "b" means is the SECOND rebuild (with "a" as the first failed attempt).
Upgrade to something more recent firmware first and see if this fixes things.
