Chapter 3 Upgrading Cisco Access Registrar Software

Linux Software Upgrade Overview

Step 2 If you have modified the snmpd.conf file in the /cisco-ar/ucd-snmp/share/snmpdirectory, you must back up this file before doing the upgrade process. The pkgrm removes the snmpd.conf file, even if it has been modified.

Step 3 Remove the old software using the pkgrm command.

See Using pkgrm to Remove Cisco Access Registrar Solaris Software.

Step 4 If you plan to use the Cisco AR SNMP features, disable the current Sun SNMP daemon and prevent the Sun SNMP daemon from restarting after a reboot.

Step 5 Decide where to install the CAR 4.2 software.

Step 6 Decide if you want to preserve your existing configuration database.

Preserving your existing configuration database is a compelling reason to upgrade rather than to start anew. The upgrade procedure in this chapter assumes you want to preserve your existing configuration.

If you are upgrading from Cisco AR 1.7 or an earlier version, the default installation directory is /opt/AICar1. The default installation directory for Cisco AR is /opt/CSCOar.

If your previous install directory was /opt/AICar1, you should use that directory to install CAR 4.2 You might also rename the old directory, as in the following:

cd /opt

mv AICar1 CSCOar

Step 7 Copy the CAR 4.2 license file to a location on the Cisco AR workstation directory such as /tmp.

For detailed information about the Cisco AR license and how to install the license, see Cisco Access Registrar 4.2 Licensing.

Step 8 Use the pkgadd command to install the CAR 4.2 software.

For detailed information about using the pkgadd command to install Cisco AR software, see Chapter 2, “Installing Cisco Access Registrar 4.2 Software on Solaris.”

Note Since you are upgrading, you will want to preserve your existing database.

Step 9 If you configured Cisco AR to use SNMP prior to upgrading, after installing CAR 4.2 software, you must copy the snmpd.conf file back to the /cisco-ar/ucd-snmp/share/snmpdirectory.

Step 10 Restart the Cisco AR server using the following command:

/etc/init.d/arserver restart
