The Devices widget, SEGMENT CONTROLLERS tab, allows you to erase data on the SD card, as well as to reformat the SD card, using the CMS. You can also erase data on the SD card using the SmartServer Linux console. This section describes these operations and consists of the following:

Determining SD Card Usage

For SmartServer 3.3 and prior, use the Storage widget as described in Managing the SmartServer SD Card (Release 3.3 and Prior) to determine the SD card usage.

For SmartServer 3.4 and higher, use the SmartServer app bar Storage display to determine the SD card usage. Storage reflects percentage used internal storage (stored in /var/apollo)  / percentage used SD card storage (stored in /media/sdcard).
