Uninstalling Data Protection for VMware a Linux system

You can uninstall Data Protection for VMware on a supported Linux operating system.

About this task

When you uninstall Data Protection for VMware on a Linux system, by default, the type of uninstallation is the same process as the type of original installation. To use a different uninstallation process, specify the correct parameter. For example, if you used a silent installation process, you can use the installation wizard to uninstall by specifying the –i swing parameter. Run the uninstallation process as the root user. The root user profile must be sourced. If you use the su command to switch to root, use the su - command to source the root profile.

When the uninstall process begins removing program files, canceling the uninstall process does not return the system to a clean state. This situation might cause the reinstallation attempt to fail. As a result, clean the system by completing the tasks that are described in Manually removing Data Protection for VMware from a Linux system.

To uninstall Data Protection for VMware, complete the following steps:

Procedure

Change to the directory for the uninstallation program. The following path is the default location to the uninstallation program: /opt/tivoli/tsm/tdpvmware/_uninst/TDPVMware/
Depending on the type of installation, use one of the following methods to uninstall Data Protection for VMware:
- To use the installation wizard to uninstall Data Protection for VMware, enter this command:
```
./Uninstall_Tivoli_Data_Protection_for_VMware –I swing
```
- To use the console to uninstall Data Protection for VMware, enter this command:
```
./Uninstall_Tivoli_Data_Protection_for_VMware -i console
```
- To silently uninstall Data Protection for VMware, enter this command:
```
./Uninstall_Tivoli_Data_Protection_for_VMware -i silent -f uninstall.properties
```
  The uninstall.properties file contains the vCenter or vCloud connection information. This information is needed to uninstall the Data Protection for VMware vSphere GUI or Data Protection for VMware vCloud GUI.
