Downloading a New Software Version
(which is mounted read only), and the third partition (which is mounted read
write) contains the configuration files.
Figure A-1: Boot Partitions
The previous figure also shows a configuration backup partition (/dev/
hda3 in removable flash). This partition is mounted as /mnt/hda3. The
/mnt/hda3/backup directory contains compressed copies of backed up
configuration files, as shown in the following screen example.
Downloading a New Software Version
You can download a new software version in either of the following ways:
• Use the Web Manager → Firmware Upgrade screen to download the
image from an FTP server
When the image is downloaded by FTP, a script (saveimage)
automatically extracts the filesystem from the image, mounts it, and
copies the files to the removable flash. Since the current image is being
run from one of the three-partitions sets, the downloaded image is stored
in the other set of three partitions. The environment variable
[root@ONS /]# cd /mnt/hda3/backup
[root@ONS /]# ls
