SERVERware 3 Mirror to Cluster Edition Upgrade

To update SERVERware 3 from Mirror to Cluster edition following procedure should be used.

First, log in to your SERVERware 3 GUI, go to "MAIN MENU ---> HOSTS" and then in the bottom section switch to Network interfaces. Here we can see the list of our network interfaces and we have a free network interface to create a SAN network (adding the SAN network should be done manually).

In this picture, we can see there is an unused network interface named "enp0s20f1". We will use this interface for our SAN network.

Now go to the terminal and using ssh login to the primary or secondary server and run "netsetup" utility.

We will use the existing network interface. In the case that you need to bond 2 or more interfaces, you can pick 'Create virtual bonding network interface' option.

Next, enter address parameters as required (detail information on SAN network addressing can be found in the installation of cluster edition wiki page)

In our case we will use the following configuration:

Storage Server-primary: 192.168.2.2

Storage Server-secondary: 192.168.2.1

Floating SAN address: 192.168.2.3

Press Finish to confirm.

Now on the same server, we need to edit mirror.cfg file.

To edit, type in the terminal:

#: nano /etc/sysmonit/mirror.cfg

Add lines highlighted with green colour in the same place after brackets.

,
    {
            "name": "enp0s20f1",
            "address": "192.168.2.3"
        }

Save the file and log out from the first server.

Now we need to repeat all of the above steps on the second server

After these steps are done on both storage servers, ssh to the primary server and export virtual SAN address with this command:

#: ifconfig enp0s20f1:VIRT 192.168.2.3 

And restart sw-connector

#: /etc/init.d/sw-connector restart

We now have a few modifications in the SERVERware 3 GUI.

Now login to GUI and go to the MAIN MENU ---> Settings ---> Networking and add another network subnet as described in the next image:
