Compaq OXYGEN VX1 - Manual (Page 29)

Compaq OpenVMS Software Installation and Customization 4-7
4.9 POLYCENTER Software Installation
At the end of the OpenVMS POLYCENTER Software Installation procedure, a
message is displayed that recommends a reboot of the system. At the conclusion
of the installation, the POLYCENTER Software Installation utility does not
prompt for or enforce a reboot of the system for the new software image to
become effective immediately. The 3Dlabs OXYGEN VX1 PCI graphics
controller two-dimensional (2D) support software becomes active only after the
operating system has been rebooted.
If the software is being installed in a clustered environment and it is not
convenient to perform a reboot immediately following installation, then a rolling
reboot may be used for the new image to take effect across all systems.
