Hi, I am facing an issue in new F5 i 2600 appliance. Issue is that httpd is not started. I tried to restart the httpd service via cli

I'd recommend opening up a support case with F5 support. There are logs on the device for the management httpd service, but typically you shouldn't be troubleshooting it yourself unless you've made changes to it manually -- which usually isn't supported.

There's probably more going on and support will be able to identify it pretty quickly.
