Introduction:

Introduction:  

Client Automation assigns each managed computer a CA Technologies-specific Universal Unique Identifier (UUID). It is stored on each computer at the following locations:

x32 Windows registry:      HKEY_LOCAL_MACHINE\Software\ComputerAssociates\HostUUID
x64 Windows registry:      HKEY_LOCAL_MACHINE\Software\Wow6432Node\ComputerAssociates\HostUUID
Linux/UNIX:               /etc/cadmuuid                                   


The Hostuuid can change if any of the following items changes:

Virtual machine :     System ID (a system BIOS attribute) is the only characteristic checked by the algorithm.

Physical computer: 

   ? MAC address compliance  -    If one of the MAC addresses does not match with one of the original MAC addresses of the target.

   ? Hard disk serial number compliance  - If one of the Hard Disk serial numbers does not match with one of the original hard disk serial numbers of the target.

   ? System ID compliance   -  If the System ID does not match with the original System ID of the target.

 

Question:

   How do I lock the Hostuuid for some or All agents.

 

Environment:   

  CA Client Automation R14                                       

 

Answer:

In previous version you could lock the hostuuid by the following steps:

 Windows:        Create a string value LockHostUUID with value “1”, under the registry key HKLM\Software\ComputerAssociates\HostUUID.

 Linux/UNIX:   Create a file named /etc/calockuuid.

 

The new way to do it in  CA Client Automation R14:  

Once you have installed R14, there will be a new Configuration Policy created under : Default Computer Policy\DSM\Agent      

Lock the host UUID of agent                 Set to TRUE

You can either update the Default configuration Policy and then it will update all machines.

OR

You can create a Custom Policy and only apply it to a single machine or Group.
