How to add free cisco licenses to Cisco Unified Communications Manager7.x

This process should only be used in "your Lab environment", furthermoreyou should never use this process in a production environment, do thisprocess at your own risk, this process is for educational purposes only

I have test the process succesfully inUCM version 7.x7845-H1The integrity of both partition are good after thetrick, data and contentsYou must have experience with vi and linuxThis trick should work on all Cisco IPT products runninglinux of course.

The license process involve 3 files-LicenseScript.sh Located in /usr/local/platform/bin-LicenseParams.xml Located in /usr/local/cm/conf-VMLicenseParams.xml Located in /usr/cm/conf

First and fost most, you must gain access to the UCM withRoot Rights, to do this follow the following stepsSo, I will call this the Remote Account Process.On a working server or environment we will do the following:-Connect to the UCM Console using an SSH Client-Proceed to a enable a remote accountadmin:utils remote_account enable-Proceed to create a remote_account useradmin:utils remote_account create [ournew_remote_account_username] [amount of day's thatwe want this account to remain active]exampleadmin:utils remote_account create ciscotac 30-the above example will create a remote account user named ciscotac and it will be validfor 30 days.-Once we have succesfully created a remote_account we will proceed to reboot the servercleanly.admin:utils system restart-Proceed to insert the CentOS 5.2 Disk 1-on the Boot option enter linux rescueboot:linux rescue-Once you are in the linux shell-Proceed to do the following#chroot /mnt/sysimage#lsattr /etc/passwd /etc/group /etc/shadow /etc/gshadow#chattr -i /etc/passwd /etc/shadow /etc/group /etc/gshadow#passwd [enter the username that you have created for the remote account user]-Enter the new password that you want for the new remote account user twice-eject the CentOS 5.2 DISK 1-Reboot the server by doing the following#shutdown -r now-Once Unified Communications Manager have completed rebooted, simply using an SSHclient login to UCM using the remote account username and password, you will seethe following messageWelcome to Remote Support[root@EDGE1 ~]#

-Now once in the box logged in as a member of the Cisco Tac Team, proceed todo the following[root@EDGE1 ~]# cd /usr/local/platform/bin[root@EDGE1 bin]#vi LicenseScript.shThe original script should look like this**********************************

LicenseScript.sh, which is the one that controls the activation of thelicense engine, basically it stops and starts the LicenseMgr servicethis file is located in/usr/local/platform/bin

#!/bin/bash

---Basically what we modified in the above script is swapthe VMLicensingCfg.xml for Licensingcfg.xml positions.

---Now we need to go to/usr/local/cm/conf[root@ucmpub1 conf]#

Once you are in the above directory you will need to proceed to modify the valuesof the files respectively, ie nodes amount ( you should see >150< thatsthe amount of dlu's currently, here is where you can change the amount towhatever you want, using vi change the values in theLicenseParams.xml and VMLicenseParams.xml files "the new values need to match" inboth files in order for the crack to work. Once you have modified both files with thevalues that you want, proceed to restart the service by going to[root@EDGE1 ~]# cd /usr/local/platform/bin[root@ucmpub1 bin]# ./LicenseScript.sh stop[root@ucmpub1 bin]# ./LicenseScript.sh start-Then proceed to exit the root console and go to the cisco cli , and do a restartfrom there not from the root console, this will screw up few things,admin:utils system restart

Go to the ccmadmin page and enjoy your new dlu's

The licensemanager was able to authenticate the process, and you now have new dlu's toplay with.

Q&A

Can you go backwards to the other partition and still have the DLU's, nope, everytimeyou upgrade ucm, new rpms are added and most importantly, config files are matched,hence the hack on the script file goes back, hence you no longer have dlu's in this partitionbut you still have those dlu's in your crack partition. So what you want to do iswhenever you upgrade to a new partition is first backup your info, then do the hack on theupgrade partition then do a restore and that should be it!
