Upgrading an Installed EM

Upgrading procedures are described in the following sections:

Upgrade Workflow

Upgrading the EM involves the following:

1. Cisco EM—Verify that an earlier version of the Cisco Access Router Manager has been installed on your system.

2. Cisco EMF —Verify that you have the following required Cisco EMF 3.2 server/client software and COM version installed before proceeding:

a. Cisco EMF 3.2

b. Cisco EMF 3.2 patch 6

Note For information on installing Cisco EMF and related patches, see the Cisco Element Management Framework Installation and Administration and the relevant Cisco Element Management Framework Release Notes.

3. Upgrading—Upgrade the Cisco Access Router Manager software according to the instructions in the "Upgrading the EM" section.

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 data such as previously installed package versions and packages required to complete the upgrade process. 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.

        UPGRADE PACKAGE

 
        ===============

 
        1)      CEMF Backup

 
        2)      Remove EM and related packages

 
        3)      Remove EM only (for multiple EM system)

 
        4)      Upgrade CEMF patch

 
        5)      Install new version of EM and related packages

 
        6)      One step upgrade automation (recommended for single EM system)

 
        q)      Quit

 
        Which option do you wish to choose?  [?,q] 

Note While all of the major upgrade procedures are available as separate steps in the upgrade menu, it is recommended that you use the one step upgrade automation option (6) for a single EM system.

Tip Enter ? for help or q to quit.

Step 5 Choose the appropriate upgrade option. For this example, assume you have chosen option number 6 for one step upgrade automation. You are prompted to enter information needed to proceed with the upgrade, including:

Whether or not to run Cisco EMF backup (not applicable for a client upgrade)
If Cisco EMF backup is desired, whether the upgrade should continue if the backup fails (not applicable for a client upgrade)
Location of the Cisco EMF patch
Performance polling rate option for EM installation

Note An additional option to remove only the EM is available for a multiple EM system.

The following output is an example of the one step upgrade automation prompts:

 
		Do you want to perform CEMF backup before the upgrade [YES]? 

 
        Should CEMF backup fail, would you want to continue with the upgrade [NO]? 

 
        Should pre-upgrade script fail, would you want to continue with the upgrade [NO]? 

 
		Enter the full path where CEMF_3.2_PATCH_170006-04 can be installed: /lauto/software/patches/CEMF_3.2_PATCH_170006-04

 
        For CARMGRm installation -

 
        Please choose from the following:

 
        1)      Use default interface polling rate for co-residency purpose.

 
        2)      Use EM customized interface polling rate for better performance.

 
		Which option do you wish to choose? [ 1 2 ]: 1

 
        Do you want to remove COMUpgd after upgrade [YES]? 

Note If the options entered in the previous steps are invalid, the script notifies you of the error, lists the valid option(s), and redisplays the selection prompt. Enter a valid selection and continue.

You can start a user session, if needed, and begin using the upgraded package. For additional information, see the "Starting a User Session" section.
