Software Upgrade Procedures
Procedure 1, Copy New Software to the Distribution Node
With this procedure you copy the new software from the distribution disk set to a local LightStream
2020 node. This local node is referred to as the distribution node. In Procedure 2, Copy New
Software to Remote Nodes, you use the distribution node as the source from which to copy the
software to other nodes in the network.
Note If for any reason you discontinue installation of this release after you have started loading
software, you should delete this release using Special Procedure A, Freeing Up Disk Space. This
minimizes the impact of the interrupted installation on future installations. When you resume
installation of this release, you must restart at the beginning of this procedure.
Overview
The following tasks are necessary for an upgrade of the distribution node (or any local node) to
Release 2.0.9 node software:
1 Connect to the Primary NP.
2 Copy Release 2.0.9 Software from Floppies to Hard Disk.
To perform these tasks, use a terminal connected to the console port of the distribution node. The
system should be running with no one else logged on the system.
Connect to the Primary NP
Step 1 Enter ‘. (backquote plus dot, that is, left single quote plus period).
Step 2 At the TCS HUB prompt, use the connect command to connect to the NP in slot 1:
TCS HUB <<A>> connect 1
You may need to press [Return] a second time after typing the connect command in order
to get a prompt from the NP.
A prompt should appear asking for a user login name:
user name:
Note If someone using the machine before you has not logged out, your prompt may be different
from the one shown here. If this occurs, log out and log back in as root.
Step 3 Log in as root. The bash prompt appears (with # indicating a root login).
user name: root
password:
bash#
If your system has only one NP, go to Step 6 now.
