WARNING:
No administration changes should be entered during the following software
upgrade procedure. There can be substantial time gaps between steps
and, since the system cannot prevent administration changes, it is up to the
system technician to make sure that none are attempted during the entire
software upgrade process.
NOTE:
This section does not apply to processor hardware upgrades such as
upgrading a 386 system to a Release 5vs/si or later system. See “Upgrades
and Additions/Software Upgrades”.
Procedure on a System using Translation Cards
The software in a Release 5vs/si or later system can be upgraded to include new
features and to fix software problems. Performing an upgrade on a standard
reliability system requires a Reset System 4 (reboot) and thus causes a service
disruption. Performing an upgrade on a high or critical reliability system requires
only a Reset System 2 (Cold-2) restart, which is less disruptive.
!
CAUTION:
Do not enter any administration changes during the following software
upgrade procedure. There can be substantial time gaps between steps
and, since the system cannot prevent administration changes, it is up to the
system technician to make sure that none are attempted during the entire
software upgrade process. This includes making sure that no one
(including the customer) is making administration changes through
connections other than through the local administration terminal.
Standard Reliability (Simplex) Systems
The software upgrade for a standard reliability system can take up to 130
minutes, during which time service is interrupted for about 15 minutes. Upgrade
software cannot be done remotely, and it must be performed at the local
terminal. Ensure that the following items are available before proceeding:
■ Generic program card with the software release running currently in the
system
■ Generic program card containing the new software to which the upgrade
is to be done
■ Translation card on which the system translations are to be saved (the
card should already be in the system)
■ Software patch (if it exists) that is currently applied to the system (this
patch is downloaded if a software backout is required)
