Partitioning a CF card or a USB disk

A CF card or a USB disk can be divided into logical devices called "partitions." Operations on one
partition do not affect the other partitions.
The following partitioning modes are available for CF cards and USB disks:
Simple—Specify the number of partitions. The system divides the CF card or a USB disk into the
•
specified number of partitions with the same size.
Interactive—The system partitions the CF card or a USB disk according to user input. Each partition
•
must be at least 32 MB.
Restrictions and guidelines
It is normal that the specified partition size and the actual partition size have an error less than 5% of the
total memory.
Before partitioning a CF card or USB disk:
Back up the files in the storage medium. The partition operation clears all data in the medium.
•
If you are partitioning a USB disk, make sure the disk is not write protected. Otherwise, the partition
•
operation will fail, and you must remount or reinstall the disk to restore normal access to the USB
disk.
Make sure no other users are accessing the medium. Otherwise, the partition operation fails.
•
After partitioning a CF card or USB disk:
Reconfigure paths of application files to include the correct partition information.
•
If the device starts up from the CF card, put the startup software image files and the configuration
•
files in the first partition of the CF card.
• To guarantee the startup system software image and configuration files sufficient storage space, set
the path for log files to a partition other than the first partition. By default, the system automatically
saves log files to the second partition. If the path does not exist, use the info-center logfile
switch-directory command to change the path to avoid log loss. For more information about this
command, see Network Management and Monitoring Command Reference.
