Viewing and maintaining versions of the software

You can have up to two versions of the appliance software installed on the system 
at the same time. From these versions, you can choose which one is current and 
executes in the appliance. Installing a new version of the software automatically 
makes it the current version.

You can use the versions menu, which is a submenu of the main menu, to do the 
following:

✔ Identify the installed versions.

✔ Install new versions.

✔ Switch versions. 

✔ Delete a version.

✔ View which version is running.

▼ Identifying which versions of the appliance software are installed.

Select the main menu and press Enter. 

Select versions and press Enter. 

Select view and press Enter. Doing so displays a list of version numbers.

You can update the software on your cache appliance using FTP to download the 
updated files. When you install a new version of the software, it becomes the 
current, running version. In addition, the appliance copies the new version to 
your secondary drive.

▼ Setting up the FTP server

Set up the FTP server to provide upgrade files to the appliance. You can use a 
single FTP server to upgrade multiple appliances.

Place the files on an FTP server that’s accessible by the appliance, and on a 
network with sufficient performance for fast transfer of files.

Each upgrade must exist in a separate directory. We recommend that the 
names you choose for your directories indicate the release. This example 
shows separate directories for application, patch, and OS/application 
upgrades:

<ftp_dir>/app_3.0.9.0

<ftp_dir>/app_3.1.0.0

<ftp_dir>/patch_1

<ftp_dir>/patch_2

<ftp_dir>/os_1

<ftp_dir>/os_2
