Software Upgrade Procedures
When the program prompts you for a diskette, insert the first diskette (of the diskette set
that you are currently installing) into the appropriate drive and press [Return]. Repeat as
the program prompts you for more diskettes in the current set.
Step 8 Repeat Step 7 for each diskette set, following the order given under Step 6.
Procedure 2, Copy New Software to Remote Nodes
With this procedure you distribute new software from the distribution node to other LightStream
2020 nodes. Carry out this procedure for each remote node in turn. Then carry out Procedure 3,
Change the Running Software Version, for each remote node in turn. After all other nodes have and
are running the new software, carry out Procedure 3, Change the Running Software Version, on the
distribution node.
Note It is also possible to upgrade software directly from the distribution diskettes on each node in
your LightStream 2020 network. To do this, carry out Procedure 1, Copy New Software to the
Distribution Node, and Procedure 3, Change the Running Software Version, on each node in the
network.
Requirements for Performing the Procedure
The following connectivity requirements apply:
Overview
Carry out these tasks for each node in your LightStream 2020 network in turn:
1 Verify Remote Command Execution
2 Distribute Release 2.0.9 to the Remote Node
Verify Remote Command Execution
Verify that it is possible to execute commands on the remote node from the distribution node.
Step 1 On the distribution node, execute the following command:
bash# rsh remote-node hostname
Distribution Node Remote Node
• You should be logged in to the distribution
node.
• No other user should be logged in.
• The distribution node must be running
LightStream 2020 application software.
• You do not need to be physically located at the
remote node site. However, you must be able to
establish an rsh connection and a modem connection
to each remote site.
• The remote node must be running LightStream 2020
