File system management
This chapter provides information about file system management.
The file system
The 7210 SAS file system is used to store files used and generated by the system; for example, image files, configuration files, logging files and accounting files.
The file commands allow you to copy, create, move, and delete files and directories, navigate to a different directory, and display file or directory contents and the image version.
Compact flash devices
The file system is based on a DOS file system. The 7210 SAS devices provide several storage options, including internal flash and USB.
The following compact flash devices are supported:
SD slot, USB slot, or internal flash, cf1:\
external USB slot, uf1:\
The preceding device names are relative device names in that they refer to the devices local to the control processor running the current console session. As in the DOS file system, the colon (‟:”) at the end of the name indicates it is a device.
The following table lists the storage locations available on different 7210 SAS platforms.

In addition to user-added files and directories, the number of files in the root directory can also increment when the admin save or bof save commands are issued. The system enforces a threshold limit of 80 entries (files and directories) for contents of the root directory on cf1:\; there is no restriction on the number of files and directories that you can add in the subdirectories. A trap (tmnxRootDirFull) is generated if the threshold limit is exceeded, and a warning is generated for each new file or directory created in the root directory on cf1:\ after the threshold limit is exceeded.
User intervention is required when the system displays the threshold exceeded event (tmnxRootDirFull). You are required to clean the root directory on cf1:\ and ensure that the number of entries (files or directories) is below the enforced threshold limit of 80 entries. Remove unnecessary files and directories from the root directory or move them to a subdirectory that you have created under the root directory. The system does not generate a warning when the number of files and directories is reduced below the threshold limit.
Use the file dir cf1:\ command to determine the number of entries (files or directories) present in the root directory, as shown in the following output example.
In the following listing, the total number of entries in the root directory (files and directories) is 14 files + 2 directories = 16.

USB storage device
USB devices are supported on all 7210 SAS platforms as described in this document, except the 7210 SAS-D and 7210 SAS-Dxp.
7210 SAS platforms support the use of the USB interface as an alternate storage location that provides a larger storage capacity than the internal flash. You can use a USB storage device to store TiMOS images, configuration files, accounting records, and log files. The BOF can point to images on the USB and you can use the USB to load TiMOS images and configuration files.
The 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C provide an option to load the boot loader (boot.tim) from the USB storage device plugged into any one of the USB ports.
The USB devices and capacities that are supported for use with 7210 SAS are listed in the 7210 SAS Software Release Notes 24.x.Rx.
When a USB device is unplugged or removed from the system, a major alarm is raised. The alarm can be cleared using the shutdown command.
7210 SAS also auto-detects the device type when any of the supported devices are connected to the USB interface. Only approved USB mass storage devices and optical clip-on devices can be plugged in to the USB port and are recognized as valid devices. All other unsupported devices result in an error log being printed.
Nokia recommends using the shutdown command before removing the USB storage device.
URLs
The arguments for the 7210 SAS file commands are modeled after standard universal resource locators (URLs). A URL refers to a file (file-url) or a directory (directory-url).
The 7210 SAS supports operations on both the local file system and remote files. For the purposes of categorizing the applicability of commands to local and remote file operations, URLs are divided into three types: local, ftp and tftp. The following table describes the syntax for each of the URL types.
URL type |
Syntax |
Notes |
|---|---|---|
local-url |
[cflash-id:\]path [usb-flash-id:\] path |
cflash-id is the compact flash device name Values: cf1: usb-flash-id is the USB device name Values: uf1: |
ftp-url |
ftp://[username[:password]@]host/path |
An absolute ftp path from the root of the remote file system username is the ftp username password is the ftp user password host is the remote host path is the path to the directory or file |
ftp://[username[:password]@]host/./path |
A relative ftp path from the user’s home directory Note the period and slash (‟./”) in this syntax compared to the absolute path |
|
tftp-url |
tftp://host[/path]/filename |
tftp is only supported for operations on file URLs |
The system accepts either forward slash (‟/”) or backslash (‟\”) characters to delimit directory and filenames in URLs. Similarly, the 7210 SAS SCP client application can use either slash or backslash characters, but not all SCP clients treat backslash characters as equivalent to slash characters. In particular, UNIX systems often interpret the backslash character as an ‟escape” character. This can cause problems when using an external SCP client application to send files to the SCP server. If the external system treats the backslash like an escape character, the backslash delimiter is stripped by the parser and not transmitted to the SCP server.
For example, a destination directory specified as ‟cf1:\dir1\file1” is transmitted to the SCP server as ‟cf1:dir1file1”, where the backslash escape characters are stripped by the SCP client system before transmission. On systems where the client treats the backslash like an ‟escape” character, a double backslash ‟\\” or the forward slash ‟/” can typically be used to correctly delimit directories and the filename.
All the commands can operate on the local file system. The following table describes which commands also support remote file operations.

A:ALA-1>file cf1:\siliconvalley\ #File management tasks
The following sections contain information about the basic system tasks.
When a file system operation is performed with a command that can potentially delete or overwrite a file system entry (such as a copy, delete, move, rd, or scp command), a prompt appears to confirm the action. The force keyword performs these file management operations without displaying the confirmation prompt.
Modifying file attributes
The system administrator can change the read-only attribute in the local file. Enter the attrib command with no options to display the contents of the directory and the file attributes.
Use the following CLI syntax to modify file attributes.

Description
This command sets or clears the read-only attribute for a file in the local file system. To list all files and their current attributes enter attrib or attrib x where x is either the filename or a wild-card (*).
When an attrib command is entered to list a specific file or all files in a directory, the file’s attributes are displayed with or without an ‟R” preceding the filename. The ‟R” implies that the +r is set and that the file is read-only. Files without the ‟R” designation implies that the -r is set and that the file is read-write-all.
Parameters
- file-url
Specifies the URL for the local file.
- +r
Keyword to set the read-only attribute on the specified file.
- -r
Keyword to clears/reset the read-only attribute on the specified file.

file
Platforms
Supported on all 7210 SAS platforms as described in this document
Description
This command copies a file or all files in a directory from a source URL to a destination URL. At least one of the specified URLs should be a local URL. The optional wild-card (*) can be used to copy multiple files that share a common (partial) prefix and/or (partial) suffix. When a file is copied to a destination with the same file name, the original file is overwritten by the new file specified in the operation. The following prompt appears if the destination file already exists:
‟Overwrite destination file (y/n)?”
For example:
To copy a file named ‟srcfile” in a directory called test on cf1 to a file called ‟destfile‟ in a directory called production on cf1, the syntax is:
sr1>file cf1:\ # copy
cf2-/test/srcfile/production/destfile
To FTP a file named ‟121201.cfg” in directory mydir stored on cf1 to a network FTP server with IP address 192.0.2.79 in a directory called backup with a destination file name of ‟121201.cfg” the FTP syntax is:
