Chapter 1  File System Management

 

 

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).

 

 

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.

l           With 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.

l           The commands used to manipulate files, such as dir, copy, delete, and move, apply to the files on a CF card.

l           You 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

 

 

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:

l           Creating/deleting a directory

l           Displaying the current directory

l           Displaying the information about the files or the directories in the current directory or a specified directory

l           Entering 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

 

 

1.1.5  File-Related Operations

The file system provides the following file-related operations.

l           Deleting a file

l           Restoring a deleted file

l           Deleting a file completely

l           Managing a configuration file

l           Renaming a file

l           Copying a file

l           Moving a file

l           Displaying the content of a file

l           Displaying the information about a file

l           Checking file system

l           Executing a batch file

Perform the following operations to perform file-related configuration:

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

 

 

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 the storage 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.

 

1.1.8  File System Configuration Example

# Display all the files in the root directory of the file system on the local unit.

<H3C> dir /all

Directory of flash:/
