Running the uninstallsfrac utility

You can run the script from any node in the cluster, including a node from which you are uninstalling Storage Foundation 5.0 for Oracle RAC.

  Note   Prior to invoking the uninstallsfrac script, all service groups must be brought offline and VCS must be shut down.

For this example, Storage Foundation 5.0 for Oracle RAC is removed from the node named saturn.

 To run the uninstallsfrac utility

1. Before starting ./uninstallsfrac, execute:

   #/opt/VRTSvcs/bin/hastop -local

2. As root user, start the uninstallation from any node from which you are uninstalling Storage Foundation 5.0 for Oracle RAC. Enter:

   # cd /opt/VRTS/install

   # ./uninstallsfrac

3. The welcoming screen appears, followed by a notice that the utility discovers configuration files on the system. The information lists all the systems in the cluster and prompts you to indicate whether you want to uninstall from all systems. You must answer " n." For example:

VCS configuration files exist on this system with the following

information:

Cluster Name: rac_cluster101

Cluster ID Number: 7

Systems: galaxy nebula saturn

Service Groups: cvm oradb1_grp

Do you want to uninstall SFRAC from these systems? [y,n,q] (y) n

  Caution   Be sure to answer N. Otherwise the utility begins the procedure to uninstall Storage Foundation 5.0 for Oracle RAC from all systems.

4. The installer prompts you to specify the name of the system from which you are uninstalling Storage Foundation 5.0 for Oracle RAC:

Enter the system names separated by spaces on which to uninstall

SFRAC:saturn

5. The uninstaller checks for Storage Foundation 5.0 for Oracle RAC packages currently installed on your system. It also checks for dependencies between packages to determine the packages it can safely uninstall and in which order.
6. Enter y when the uninstaller has completed checking.
7. When you press Enter to proceed, the uninstaller stops processes and drivers running on each system, and reports its activities.
8. When the installer begins removing packages from the systems, it indicates its progress by listing each step of the total number of steps required.
9. When the uninstaller is done, it describes the location of a summary file and a log of uninstallation activities.
