Once the update has completed, ensure your prompt reads, “Update completed with no errors”
6. Verify update and perform system restart
Perform a system restart by typing: restart [Enter] into the unix shell. It’s important to note the system will not restart to applications. System applications will require manual boot via the unix shell after system restart procedure
7. Start system applications.
Once system has restarted, open a unix shell and type: st [Enter] to boot applications.
