Upgrading the EM

After you have ensured that the proper versions of Cisco Access Router Manager and Cisco EMF have been installed on your system, you can initiate the upgrade procedures using an install script.

As part of the upgrade process, the system performs the following steps:

•System analysis—Before the upgrade process begins, the install script analyzes the system and displays related information such as previously installed package versions and package versions required to complete the upgrade process successfully. The script also checks for the current Cisco EMF version and patch levels. The user is alerted if there is a potential problem (either missing information or version incompatibility.)

•CEMF backup—This step is optional, but recommended. If upgrading a client machine, this step can be skipped.

•Remove EM and associated EM packages—A customized load script is used to remove packages when the -o- upgrade option is required.

•Cisco EMF patch update—Cisco EMF is stopped, the latest patch is installed, then the Cisco EMF system is started again.

•EM installs—The newest version of the EM is loaded onto the system.

To upgrade the EM using the install script:

Step 1 Ensure you are logged in as a root user on the workstation where the EM package you want to upgrade is installed.

Step 2 Perform one of the following, as appropriate:

a.Insert the Cisco Access Router Manager CD–ROM and make the CD–ROM area your working directory by entering the following at a command prompt:

cd /cdrom/cdrom0

b.Navigate to the directory where the EM package is installed by entering the following at a command prompt:

cd CEMF_Root/bin

(Replace CEMF_ROOT with the name of the directory where Cisco EMF is installed.)

Step 3 Run the install script with the upgrade option by entering the following at a command prompt:

./CAccessRouterMGRinstall -u

The installation script analyzes the system and provides related information. The following depicts an example of the type of data displayed in the command window..
