File system management commands

IMPORTANT: ·     Before managing storage media, file systems, directories, and files, make sure you know the possible impacts. ·     A file or directory whose name starts with a period (.) is considered a hidden file or directory. Do not give a common file or directory a name that starts with a period. ·     Some system files and directories are hidden.

 

A file name must be specified in one of the file name formats allowed. For more information, see Fundamentals Configuration Guide.

Before you use the copy, delete, fixdisk, format, gunzip, gzip, mkdir, move, rename, rmdir, or undelete command on a USB disk, make sure the disk is not write protected.

You cannot access a storage medium that is being partitioned, or a file system that is being formatted or repaired. To access a storage medium after it is partitioned or a file system after it is formatted or repaired, use one of the following methods:

·     Use the absolute path to specify a file or directory. For example, use the dir flash:/ command to display the files and directories in the flash: file system.

·     Use the cd command to change the working directory to the root directory of the file system before accessing a file or directory in the file system. For example, to display the files and directories in the root directory of the flash: file system, perform the following tasks:

a.     Use the cd flash:/ command to change the working directory to the root directory of the file system.

b.     Execute the dir command.

The device supports the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for features, commands, and parameters might differ in FIPS mode and non-FIPS mode. For more information about FIPS mode, see Security Configuration Guide.

cd

Parameters

directory: Specifies the destination directory.

..: Specifies the parent directory. If the current working directory is the root directory, an error message appears when you execute the cd .. command. No online help information is available for this keyword.

Examples

# Access the test directory after logging in to the device.

<Sysname> cd test

# Return to the upper directory.

<Sysname> cd ..

# (In standalone mode.) Change to the test directory in the root directory of the active MPU:

1.     Display the number of the slot where the standby MPU resides.

The output shows that the IRF fabric has two members and four MPUs.

¡     The global active MPU resides in slot 5 of member device 3.

¡     The three global standby MPUs reside in slot 0 and slot 1 of member device 2, and slot 6 of member device 3.

2.     Access the test directory in the root directory of the flash memory on the global active MPU.

<Sysname> cd flash:/test

3.     Change to the root directory of the flash memory on the global standby MPU that resides in slot 1 of member device 2.

<Sysname> cd chassis2#slot1#flash:/

4.     Change to the test directory in the root directory of the flash memory on the global active MPU.

<Sysname> cd flash:/

copy

Use copy to copy a file.

Syntax

In non-FIPS mode:

copy source-file { dest-file | dest-directory } [ vpn-instance vpn-instance-name ] [ source interface interface-type interface-number ]

In FIPS mode:

copy source-file { dest-file | dest-directory }

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

source-file: Specifies the name or URL of the file to be copied in non-FIPS mode, and specifies the name of the file to be copied in FIPS mode. If the file resides on an FTP, TFTP, or HTTP server rather than on the device, specify the URL of the file. Whether a URL is case sensitive depends on the server.

dest-file: Specifies the name or URL for the destination file in non-FIPS mode, and specifies the name for the destination file in FIPS mode. To copy the source file to an FTP, TFTP, or HTTP server, specify a URL. Whether a URL is case sensitive depends on the server.

dest-directory: Specifies the destination directory or URL in non-FIPS mode, and specifies the destination directory in FIPS mode. To copy the source file to an FTP, TFTP, or HTTP server, specify a URL. The device copies the source file to the destination location and saves the file with its original file name. Whether a URL is case sensitive depends on the server.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination FTP, TFTP, or HTTP server belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive string of 1 to 31 characters. If the server belongs to the public network, do not specify this option.

source interface interface-type interface-number: Specifies the source interface used to connect to the server. After you specify the source interface, the device uses the primary IP address of the source interface as the source IP address for outgoing packets. If you do not specify this option, the device uses the outgoing interface as the source interface.

Usage guidelines

In FIPS mode, the copy command can only copy a local file and save it locally.

In non-FIPS mode, you can use the copy command to perform the following tasks:

·     Copy a local file and save it locally.

·     Copy a local file and save it to an FTP or TFTP server.

·     Copy a file from an FTP, TFTP, or HTTP server and save it locally.

To specify a file or directory, use the following guidelines:

 

Location	Name format	Remarks
On the device	Use the file name guidelines in Fundamentals Configuration Guide.	N/A
On an FTP server	Enter the URL in the format of ftp://FTP username[:password]@server address[:port number]/file path[/file name].	The username and password must be the same as the username and password configured on the FTP server. If the server authenticates users only by the username, you are not required to enter the password. For example, to use the username a and password 1 and specify the startup.cfg file in the authorized working directory on the FTP server 1.1.1.1, enter ftp://a:1@1.1.1.1/startup.cfg. To specify an IPv6 address, enclose the IPv6 address in square brackets ([ ]), for example, ftp://test:test@[2001::1]:21/test.cfg.
On a TFTP server	Enter the URL in the format of tftp://server address[:port number]/file path[/file name].	For example, to specify the startup.cfg file in the working directory on TFTP server 1.1.1.1, enter the URL tftp://1.1.1.1/startup.cfg. To enter an IPv6 address, enclose the IPv6 address in square brackets ([ ]), for example, tftp://[2001::1]:21/test.cfg.
On an HTTP server	Enter the URL in the format of http://[HTTP username[:password]@ ]server address[:port number]/filepath[/file name].	The username and password in the URL must be the same as the username and password configured on the server. If only the username is required for authentication, you do not need to enter the password. If authentication is not required, you do not need to enter the username or password. For example, the startup.cfg file is saved in the authorized directory on the HTTP server at 1.1.1.1. The HTTP account username and password are a and 1, respectively. To copy the file, enter the URL http://a:1@1.1.1.1/startup.cfg. If authentication is not required, enter the URL http://1.1.1.1/startup.cfg. To enter an IPv6 address, enclose the IPv6 address in square brackets ([ ]), for example, http://test:test@[2001::1]:21/test.cfg.

delete

Use delete to delete a file.

Syntax

delete [ /unreserved ] file

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

/unreserved: Permanently deletes the specified file. If you do not specify this keyword, the command moves the file to the recycle bin.

file: Specifies the name of the file to be deleted. Asterisks (*) are acceptable as wildcards. For example, to remove files with the .txt extension in the current directory, enter delete *.txt.

Usage guidelines

Use the delete /unreserved file command with caution. You cannot restore a file that was deleted with this command.

The delete file command (without /unreserved) moves the specified file to the recycle bin, except in the following two situations, where the file is permanently deleted:

·     The device is running out of storage space.

·     You are logged in to the default MDC and are using this command to delete a file from a non-default MDC.

A file moved to the recycle bin can be restored by using the undelete command.

Do not use the delete command to delete files from the recycle bin. To delete files from the recycle bin, use the reset recycle-bin command.

If you delete two files that have the same name from different directories, both files are retained in the recycle bin. If you successively delete two files that have the same name from the same directory, only the most recently deleted file is retained in the recycle bin.

Examples

# (In standalone mode.) Remove file 1.cfg from the root directory of the active MPU's flash memory.

<Sysname> delete 1.cfg

Predefined user roles

network-admin

Parameters

medium: Specifies the name of the storage medium to be partitioned.

partition-number: Specifies the number of partitions, in the range of 1 to 4. If you specify this argument, the storage medium is divided evenly into the specified number of partitions. To customize the sizes of partitions, do not provide this argument.

Usage guidelines

This command is supported only on the default MDC.

The flash memory cannot be partitioned. A partition cannot be partitioned.

The actual partition size and the specified partition size might have a difference of less than 5% of the storage medium's total size.

Before partitioning a USB disk, perform the following tasks:

·     Back up the files in the storage medium. The partition operation clears all data on the medium.

·     Make sure no other users are accessing the medium.

·     Make sure the USB disk to be partitioned is not write protected. If the USB disk is write protected, the operation will fail, and you must remount or reinstall the disk to restore access to the USB disk.

network-admin

Parameters

filesystem: Specifies the name of a file system.

Usage guidelines

This command is supported only on the default MDC.

Generally, file systems on a hot-swappable storage medium are automatically mounted when the storage medium is connected to the device. If the system cannot recognize a file system, however, you must mount the file system before you can access it.

To avoid file system corruption, do not perform the following tasks while the system is mounting a file system:

·     Install or remove storage media.

·     Install or remove cards.

·     Perform an active/standby switchover. (In standalone mode.)

·     Perform a switchover between the global active MPU and a global standby MPU. (In IRF mode.)

To avoid file system corruption, do not create, delete, start, or stop an MDC while the system is mounting or unmounting a file system.

Examples

# (In standalone mode.) Mount the usba0: file system on the active MPU.

<Sysname> mount usba0:                                                              

Mount usba0: successfully.

# (In standalone mode.) Mount the usba0: file system on the standby MPU (in slot 6).

<Sysname> mount slot6#usba0:                                                        

Mount slot6#usba0: successfully.

# (In IRF mode.) Mount the usba0: file system on the global MPU.

<Sysname> mount usba0:

Mount usba0: successfully.

# (In IRF mode.) Mount the usba0: file system on the global standby MPU that resides in slot 6 of member device 2.

<Sysname> mount chassis2#slot6#usba0:

Syntax

umount filesystem

Views

User view

Predefined user roles

network-admin

Parameters

filesystem: Specifies the name of a file system.

Usage guidelines

This command is supported only on the default MDC.

File systems on a storage medium are automatically mounted when the storage medium is connected to the device. To remove a hot-swappable storage medium from the device, you must first unmount all file systems on the storage medium. Removing a mounted hot-swappable storage medium might damage files on the storage medium or even the storage medium.

You can unmount a file system only when no other users are accessing the file system.

To avoid file system corruption, do not perform the following tasks while the system is unmounting a file system:

·     Install or remove storage media or cards.

·     Perform active/standby switchover. (In standalone mode.)

·     Perform a switchover between the global active MPU and a global standby MPU. (In IRF mode.)

Examples

# (In standalone mode.) Unmount the usba0: file system from the active MPU.

<Sysname> umount usba0:

Umount usba0: successfully.

# (In standalone mode.) Unmount the usba0: file system from the standby MPU (in slot 6).
