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
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.
? 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.
How do I lock the Hostuuid for some or All agents.
CA Client Automation R14
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.
You can create a Custom Policy and only apply it to a single machine or Group.
