Upgrading the appliances

In the System provisioning toolbar, select Tools and go to the Software upgrade tab.

The following window is displayed:

This window is made of two frames:

•

the list of appliances to be upgraded (left frame),

•

the list of software versions (right frame).

The procedure is as follows:

When you select this tab for the first time, the list of configured appliances is displayed in the left frame. The Version column is not filled in. Select some appliances (or all of them with the Select All button

) and click the Status button

to see the actual software versions and statuses of the selected devices.

The statuses can be:

•

upgraded: the appliance is up-to-date with the software release which is specified in the Version field,

•

download scheduled: the appliance will be upgraded,

•

install scheduled: the appliance is currently being upgraded,

•

error occurred: possible reason of failure:

No Space left for file: no more space on the appliance to download the file,

Cannot connect to server (check address/routes): the FTP server is unreachable,

Access to server denied (check login/password): there is a login/password problem on the FTP server,

File not found: xxxxxxx: the file is not in the right directory on the FTP server or the directory is wrong,

Error while downloading: the connection between the FTP server and the appliance is broken,

No disk space left for file: no more space to uncompress the software package.

In the right frame, click on the Get Catalog button

The Catalog Server window contains the following parameters:

•

Access Mode: three radio buttons enable you to choose between FTP, HTTP or HTTPS.

•

Server (ExtremeCloud SD-WAN domain access): host name or IP address of the server reachable by SD-WAN (which reads the appliance versions present on the server).

•

Server (appliance access): host name or IP address of the server reachable by the appliances (they will download the new software version from that server). This server can be different from the previous one in case of NATting; if it is the same, you do not need to enter it again.

•

Server port: allows changing the default port for HTTP (80 by default) and HTTPS (443 by default). For FTP, only the default port (21) can be used; in this case the field is greyed out.

•

Directory: the server directory containing the software files.

•

Password: user's password.

•

Proxy server (for HTTP and HTTPS only): IP address of the proxy, if any.

•

Proxy port (for HTTP and HTTPS only): port number of the proxy, if any.

The list of software versions on the server is displayed.

This table contains two columns:

•

software version: list of the available software versions,

•

Current version compatibility: shows the compatibility with the running version of Application Configuration software (compatible or not).

Select the appliances to be upgraded in the left frame and the software version in the right frame, then click the Upgrade button

The displayed scheduling window reminds you of the defined parameters and enables you to schedule the upgrade (during the night for example), or to launch it immediately by clicking Ok without specifying any date or time:

This window contains the following fields:

•

Start time: enter the start date and time of the upgrade (this must be a future date, not the current date). The Start time corresponds to the date when downloading from the FTP/HTTP/HTTPS server will start. The chronological sequence of downloads is managed automatically by the system.

•

End time: enter the end date and time of the upgrade (this must be a future date, not the current date). The End time corresponds to the date when downloading will end and when the appliance will reboot for the new version to be applied.

•

Mode:

Differential: download only files necessary to upgrade the current version to the new version,

Total: download all the files.

•

Password: re-enter the password.

Click on Ok when done. The restart of appliances after upgrade is automatically performed at the date/time specified by the "End time" field.

If the Start time and End time fields are empty, the upgrade starts immediately on the selected Appliances.

A message confirms that the selected Appliances have received the upgrade order.

A Cancel button allows you to cancel the upgrade request. Canceling an upgrade is possible before or during the download of the software new version, but before the Appliance has started swapping.

Check that the upgrade has been completed correctly by selecting the appropriate Appliances and by clicking on the Status button
