Reinstalling vSLX in a container

After reinstalling the xlxc bash scripts, perform this task to upgrade or downgrade a vSLX container installation—preserving your vSLX objects and configurations.

Note

This flow installs new vSLX and SLX-OS versions—while maintaining support for existing and new objects of currently installed SLX-OS versions. But if you need a clean upgrade, refer to Uninstalling vSLX completely.

1. In vShell, make sure that all devices (chassis and workstations) are powered off.
   

   (vsh) poweroff ch_9540_01

2. Make sure that any container VMs are closed.
3. Verify that all is ready for vSLX reinstallation, as follows:
   1. List the new SLX distribution directory.
      

      root@VLAB1:~# ls /slxos-dist
      extreme-lxc_2.1.0.deb  slxos18r.2.00  slxos18r.2.00.tar.gz  vslx_2.1.0.deb  vslx2.1.0.tar.gz

      

      Note

      You can also list included directories.
   2. Enter the ping command—specifying a known URL—to verify that you have internet connectivity.
      

      root@VLAB1:~# ping example.com

4. Uninstall the current vSLX distribution—preserving your vSLX objects and configurations.
   

   root@VLAB1:~$ sudo dpkg -r vslx

5. Install the vSLX debian package.
   

   root@VLAB1:/slxos-dist# sudo dpkg -i /slxos-dist/vslx_2.1.0.deb
   Selecting previously unselected package vslx.

   Preparing to unpack ./vslx_2.1.0.deb ...
   Unpacking vslx (2.1.0) ...
   Setting up vslx  (2.1.0) ...

6. Run the post-installation script.
   

   root@VLAB1:~# /VM/postinst-setup.sh

7. On the host, stop and restart the container.
   

   vlab1_user@ubuntu:~$ sudo xlxc stop VLAB1
   vlab1_user@ubuntu:~$ sudo xlxc start VLAB1
   

8. Verify that vSLX and Extreme-lxc are installed.
   

   user@ubuntu1:~$ dpkg --get-selections  | grep vslx
   vslx                                            install
   user@ubuntu1:~$ dpkg --get-selections  | grep extreme-lxc
   extreme-lxc                                     install
