The following are the detailed file system information after the upgrade:
Lan-7206#dir All-filesystems
of which flash:/ The file system can be as windwos/index.html ' target= ' _blank ' >windows file system to do additions and deletions to check operations
But system:/can not do trivial file operations, and system:/is the location of the storage system configuration
