Can I safely reboot a VMware view vCenter appliance without affecting hosts it manages or virtual desktops running on the hosts in order to troubleshoot other issues?

Greetings,

I'd like an expert to confirm that I am able to reboot a VMware Horizon View vCenter appliance without affecting operations of the four hosts it manages or the 80 or so virtual desktops in use.

I am doing this in an attempt to troubleshoot logging in as root. There are 12 failed login attempts recorded. The password in the company's password safe is not working. I tried 5 or 6 times (a few different passwords after the one in the safe didn't work) and a colleague tried as well, thus getting us to 12 failed attempts. I am following the directions here https://www.sneaku.com/2015/06/12/vrealize-operations-manager-6-0-root-account-locked/ as this vCenter appliance is 6.0. Though not vRealize Operations, I suspect the steps are the same.

Further, I am trying to login as root in order to run a shell so I can check the VMware vCenter workflow manager service and also disk space as a new vm pool I created fails to power on any of the new VMs and gives an error stating a general system error occurred connection refused. Troubleshooting that error led me to the aforementioned service and disk space as possible issues but need a shell to get that info. I am not able to run shell as administrator (receive permission error after successfully logging into the appliance with the administrator account). Then, if it ends up being one of those causing the error, fixing it so I can power on these VMs.

Whew, anyway... thanks.

vCenter Server is a management server, it will not affect ESXi hosts or it's VMs, whilst you reboot.

However vCenter services will be unavailable whilst you reboot.

Thanks, Andrew. That is what I thought but wanted confirmation as I am somewhat new to view and this environment.

FYI, while I was troubleshooting this I was able to login to the vCenter appliance web console as the vsphere.local admin. I see that the syslog service has an error stating it has reached the critical threshold. I do not see any service related to VMware vCenter workflow manager listed in the services (Administration > Deployment > System Configuration > Nodes > Related Objects).
