Appendix A—Upgrading DX System Software
From Version 1 To Version 2
Guidelines
•
A direct upgrade of a DX system is not supported. For example, to upgrade from version 1 to version 3, first
upgrade to version 2, and then to version 3.
•
Perform the upgrade during off-peak hours to ensure DX Storage and DX Content Router activities are not
disrupted, since the CSN will not be functional during the upgrade and must be restarted after the software
update.
•
You cannot cancel an upgrade mid-process (using <Ctrl> <C>).
•
If an upgrade is interrupted due to a network or hardware outage, use the csn-reset functionality to restore
the previous software version, and then attempt the upgrade again. This requires backing up the appropriate
information as detailed in these instructions. Ensure that appropriate backups are made.
NOTE: If csn-reset followed by a reinstall is not successful, contact Dell Support. For more information,
