Chapter 3 Upgrading Cisco Access Registrar Software

Upgrading Cisco Access Registrar Linux Software

Removing Old VSA Names

The upgrade process provides an analysis of the configuration database, addition of new database elements, and a search for obsolete VSA names. When this is complete, a message like the following is displayed:

##############################################################

#

#Sometimes VSAs get renamed from version to version of AR.

#The upgrade process does not automatically remove the

#old names. The upgrade process has generated a script

#to remove the old names. The script is located in:

#

#/opt/CSCOar/temp/10062.manual-deletes

#Review the script to make sure you are not using any of

#these old VSAs. Modify your configuration and your

#scripts to use the new names before you attempt to run

#the script.

#

#To run the removal script, type:

#aregcmd -sf /opt/CSCOar/temp/10062.manual-deletes

##############################################################

At this point, you should examine the script produced by the upgrade process to make sure that your site is not using any of the old VSAs. In the example above, the script can be found at /opt/CSCOar/temp/10062.manual-deletes.

Note The number preceding manual.deletes is produced from the PID of the upgrade process.

Modify your configuration and your scripts to use the new names before you attempt to run the script generated by the upgrade process.

VSA Update Script

The upgrade process builds a script you can use to update VSAs in your system.

##############################################################

#

#VSAs for the old AR version are not updated

#automatically. The upgrade process generated a script

#to perform the update. The script is located in:

#

#/opt/CSCOar/temp/10062.manual-changes

#Review the script to make sure it does not conflict with

#any of your VSA changes. Make sure you modify the script,

#if necessary, before you attempt to run it.

#

#To run the update script, type:

#aregcmd -sf /opt/CSCOar/temp/10062.manual-changes

##############################################################

Step 10 Review the script and make sure that the changes it will make do not conflict with any changes you might have made to the VSAs. Modify the script if necessary.
