Note:
You can provide the directory argument in the following two ways in this chapter.
zIn the form of [drive] [path]. In this case, the argument can be a string containing 1to
64 characters.
zBy specifying the name of a storage device, such as flash:/ and cf:/.
You can provide the file-url argument in the following two ways in this chapter.
zIn the form of [drive] [path] [file name]. In this case, the argument can be a string
containing 1 to 64 characters.
zBy specifying the name of a storage device, such as flash:/ and cf:/.
1.1 File System Configuration
1.1.1 Introduction to File System
To facilitate the management of storage devices such as the Flash of a switch, an
Ethernet switch has the file system module built in. The file system enables you to
access and manage files and directories by performing the operations of creating,
deleting, modifying, renaming a file or a directory and displaying the content of a file.
By default, a switch prompts for confirmation before executing the commands which
have potential risks (for example, deleting and overwriting files).
Note:
S7500 series switches support SRPU switchover. Both the primary and the secondary
SRPU have file system built in for you to manipulate the files on the both SRPUs. Note
that the URL of a file on the secondary SRPU must begin with slot[No.]#flash:/, where
No. is the number of the slot where the secondary SRPU is seated. Assume that the
secondary SRPU is seated in slot 1, then you need to use slot1#flash:/text.txt to identify
the file named text.txt and residing in the root directory of the secondary SRPU.

1.1.2 CF Card Configuration
By installing a CF(compact flash) card in the compact flash slot of a SRPU of an S7500
switch, you can extend the memory space of the switch.
zWith a CF card seated in the compact flash slot, you can access the root directory
of the CF card by executing the cd cf: command.
zThe commands used to manipulate files, such as dir, copy, delete, and move,
apply to the files on a CF card.
zYou can disable a CF card by using the umount cf: command. To use a disabled
CF card again, you need to remove it and install it again.
Perform the following operations to configure a CF card:
To do... Use the command... Remarks
Enter the root directory of a CF card cd cf: Required
Disable a CF card umount cf: Optional
Note:
Currently, only Salience III SRPU supports CF card.
The following table lists the operations that can be performed after you enter a directory
on a CF card.
1.1.3 File System Configuration Tasks
Complete the following tasks to perform file system configuration:
Task Remarks
Directory-Related Operations Optional
File-Related Operations Optional
Storage Device-Related Operations Optional
Prompt Mode Configuration Optional
1.1.4 Directory-Related Operations
The file system provides directory-related operations, such as:
zCreating/deleting a directory
zDisplaying the current directory

Operation Manual – File System Management
H3C S7500 Series Ethernet Switches Chapter 1 File System Management
1-3
zDisplaying the information about the files or the directories in the current directory
or a specified directory
zEntering a directory or switching to another storage device
Perform the following operations to perform directory-related configuration:
To do... Use the command... Remarks
Create a directory mkdir directory Optional
Delete a directory rmdir directory Optional
Only empty directories
can be deleted.
Display the current directory pwd Optional
Display the information about
specific directories and files dir [ /all ] [ file-url ] Optional
Enter a directory or switch to
another storage device cd directory Optional
Note:
In the output information of the dir /all command, deleted files (that is, those in the
recycle bin) are embraced in brackets.
1.1.5 File-Related Operations
The file system provides the following file-related operations.
zDeleting a file
zRestoring a deleted file
zDeleting a file completely
zManaging a configuration file
zRenaming a file
zCopying a file
zMoving a file
zDisplaying the content of a file
zDisplaying the information about a file
zChecking file system
zExecuting a batch file
Perform the following operations to perform file-related configuration:

Operation Manual – File System Management
H3C S7500 Series Ethernet Switches Chapter 1 File System Management
1-4
To do... Use the command... Remarks
Delete a file delete [ /unreserved ]
file-url
Optional
A deleted file can be
restored if you delete it by
executing the delete
command with the
/unreserved keyword not
specified. You can use the
undelete command to
restore deleted files of this
kind.
Restore a deleted file undelete file-url
Optional
This operation can only
restore the files deleted
with the /unreserved
keyword not specified.
Delete a file in the recycle
bin reset recycle-bin
[ file-url ] [ /force ] Optional
Rename a file rename fileurl-source
fileurl-dest Optional
Copy a file copy fileurl-source
fileurl-dest Optional
Move a file move fileurl-source
fileurl-dest Optional
Display the content of a
file more file-url
Optional
Currently, the file system
only supports displaying
the content of a file in
texts.
Display the information
about a directory or a file dir [ /all ] [ file-url ] Optional
Enter system view system-view —
Execute a batch file execute file-url Optional

Caution:
zFor files deleted with the /unreserved keyword not specified and with the same
names, only the latest deleted file can be restored.
zThe files which are deleted using the delete command with the /unreserved
keyword not specified are actually moved to the recycle bin and thus still take
storage space. You can clear the recycle bin to make room for other files by using
the reset recycle-bin command.
zIn the output information of the dir /all command, deleted files (that is, those in the
recycle bin) are embraced in brackets.
zIf the configuration files are deleted, the switch adopts the default configuration
when it starts the next time.
zThe execute command cannot be executed recursively.
1.1.6 Storage Device-Related Operations
With the file system, you can format a storage device, such as the Flash or a CF card.
Note that the format operation leads to the loss of all the data on thestorage device and
is irretrievable. For memory spaces that are unavailable due to unexpected errors, you
can use the fixdisk command to restore them.
Perform the following operations to perform storage device-related configuration:
To do... Use the command... Remarks
Format a storage device format device Optional
Restore a storage device fixdisk device Optional
1.1.7 Prompt Mode Configuration
You can set the file system prompt mode to be alert or quiet. When in the alert mode,
the file system prompts for confirmation when you perform irreversible operations (such
as deleting a file completely or overwriting a file). If you are in the quiet mode, you are
not prompted when you execute the operations.
Follow these steps to perform configuration on prompt mode of file system:

To do... Use the command... Remarks
Enter system view system-view —
Set the file system prompt
mode file prompt { alert | quiet }
Required
By default, the file system
prompt mode is alert.
