Chapter 1 File System Management

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:

mode file prompt { alert |

quiet }

Required

By default, the file system

prompt mode is alert.
