Setting up Update Process
No Packages marked for Update
After all updates have been applied it is recommended that you perform a soft reboot of your server using the “shutdown -r now” command from the shell prompt. This is to ensure you boot into any new kernels that YUM may have installed.
If problems are encountered while doing updates that you can not resolve, please log into myCP and open a ticket.
