Uninstall Host Drivers for Oracle Solaris 11.1 or Oracle Solaris 11.2

When you uninstall the host drivers, Oracle Virtual Networking functionality is no longer supported. The underlying Oracle Solaris OS is not affected. Also, note that unistalling the host drivers requires a reboot to purge the host drivers from memory.

1. Halt all network and storage traffic.

   For example, set the interfaces to down state, and wait for network and storage traffic to quiesce.

2. Unset the publisher by using the pkg unset-publisher command and specifying the directory where the host driver file exists.

   For example:

   pkg unset-publisher /usr/ORCLovn

3. Remove the currently installed host drivers by using the pkg uninstall command and specifying the host driver file name.

   For example:

   pkg uninstall ORCLovn-drv

4. Verify that all cabling is complete and correct.

   If the physical layer connectivity is not functional, the nodes might not come online correctly after the server is rebooted.

5. You can reboot the server to clear the host drivers from memory by using any of the following commands:

   • reboot --rv

   • shutdown -y -g0 -ib

6. Allow the server to completely reboot, then log in again ads a root user.
7. Check that no host drivers are installed by issuing the pkg list command while grepping for ORCLovn-drv which is part of the driver file name.

   For example:

   pkg list|grep ORCLovn-drv

   This command should return nothing. The absence of command output indicates that no host drivers are installed.

8. Check that none of the Oracle Virtual Networking services are running.

   For example:

   svcs xsadmd
   STATE        STIME        FMRI

   This command should return nothing. The absence of command output indicates that no host drivers are installed.

9. Check that no Oracle Virtual Networking software or dependencies are installed by issuing the modinfo command and grepping for xs.

   For example:

   modinfo | grep xs

   This command should return nothing. The absence of command output indicates that no host drivers are installed.
