Upgrading to Release 4.1
Performing a Local Upgrade
The cvx.dra file is a single bundled file that contains all the software images
required for a CVX switch software upgrade. To upgrade, reboot the CVX switch
with a flash memory card containing the following files:
• The Release 4.1 cvx.dra file
• The current config.cvx file that is running on the CVX switch
• The current boot.ini file that is running on the CVX switch
When the SCC starts up, it searches for a cvx.dra file. If this file is found, the SCC
extracts all of the component files to the flash memory card. If a new bepbr.elz or
bepfr.els file is found, the SCC automatically transfers these images to the flash
memory card on board the SCC. After extracting all files and transferring images
to SCC memory, the SCC deletes the cvx.dra file and restarts with the new
software version; the extracted files reside on the flash memory card.
When booting from a cvx.dra file, the CVX switch does not overwrite the existing
boot.ini file (instead, the cvx.dra file will copy the file called boot.new with a
default version of the file). You can open and review the contents of the boot.new
file, edit the file if necessary, and then copy it to the boot.ini file before restarting
the CVX switch, as described in this section.
Note: Allow approximately 30 minutes for the CVX switch configure
and reboot.
Note: The CVX switch must already be running Release 2.0 software or
greater to support the automated upgrade procedure.
