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 software are currently installed

Identifying which versions of the appliance software are installed.

1 Select the main menu and press Enter.

2 Select versions and press Enter.

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

Installing a new version of the appliance software

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

1Set up the FTP server to provide upgrade files to the appliance. You can use a single FTP server to upgrade multiple appliances.

2Place the files on an FTP server that’s accessible by the appliance, and on a network with sufficient performance for fast transfer of files.

3Each 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
