Formatting a file system permanently deletes all files in the file system. If a startup configuration file
exists in the file system, back up the file if necessary.
You can format a file system only when no other users are accessing the file system.
Examples
# Format file system flash:.
<Sysname> format flash:
All data on flash: will be lost, continue? [Y/N]:y
Formatting flash:... Done.
# Format the file system on the third partition of the USB disk.
<Sysname> format usba2:
All data on usba2: will be lost, continue? [Y/N]:y
