Upgrading software

This chapter describes types of software used on the switch and how to upgrade software while the switch is operating normally or when the switch cannot correctly start up.

System software file types

Software required for starting up the switch includes:

·         Boot ROM image—A .bin file that comprises a basic section and an extended section. The basic section is the minimum code that bootstraps the system. The extended section enables hardware initialization and provides system management menus. You can use these menus to load software and the startup configuration file or manage files when the switch cannot correctly start up.

·         Software images—Includes boot images and system images.

¡  Boot image—A .bin file that contains the operating system kernel. It provides process management, memory management, file system management, and the emergency shell.

¡  System image—A .bin file that contains the minimum modules required for device operation and some basic features, including device management, interface management, configuration management, and routing management.

The software images that have been loaded are called “current software images.” The software images specified to load at next startup are called “startup software images.”

These images might be released separately or as a whole in one .ipe package file. If an .ipe file is used, the system automatically decompresses the file, loads the .bin boot and system images in the file and sets them as startup software images. Typically, the Boot ROM and software images for this switch series are released in an .ipe file named main.ipe.

System startup process

Upon power-on, the Boot ROM image runs to initialize hardware and then the software images run to start up the entire system, as shown in Figure 1.

Figure 1 System startup process

Upgrade methods

You can upgrade system software by using one of the following methods:

The output in this document is for illustration only and might vary with software releases. This document uses boot.bin and system.bin to represent boot and system image names. The actual software image name format is chassis-model_Comware-version_image-type_release, for example, S5136S_EI-CMW710-BOOT-R6817P02.bin and S5136S_EI -CMW710-SYSM- R6817P02.bin.

Preparing for the upgrade

Verifying device status

1.       Verify that the system state, redundancy state, and state of each slot are stable.

<Sysname> display system stable state

System state     : Stable

Redundancy state : No redundance

  Slot    CPU    Role       State

  1       0      Active     Stable

2.       If the device is unstable, use the following commands to troubleshoot the issue:

¡  Use the display device command to verify that the device is operating correctly.

¡  Use the display ha service-group command to verify that bulk backup has been finished for all modules.

¡  Use the display system internal process state command in probe view to verify that services are running correctly.

3.       If a slot persists in unstable state or there are other unrecoverable issues, contact the technical support.

Setting up the upgrade environment

Before you upgrade system software, complete the following tasks:

·         Set up the upgrade environment as shown in Figure 2.

·         Configure routes to make sure that the router and the file server can reach each other.

·         Run a TFTP or FTP server on the file server.

·         Log in to the CLI of the router through the console port.

·         Copy the upgrade file to the file server and correctly set the working directory on the TFTP or FTP server.

·         Make sure that the upgrade has minimal impact on the network services. During the upgrade, the router cannot provide any services.

Figure 2 Setting up the upgrade environment

Upgrading from the CLI

This section uses a two-member IRF fabric as an example to describe how to upgrade software from the CLI. If you have more than two subordinate switches, repeat the steps for the subordinate switch to upgrade their software. If you are upgrading a standalone switch, ignore the steps for upgrading the subordinate switch. For more information about setting up and configuring an IRF fabric, see the installation guide and IRF configuration guide for the H3C S5136S-EI switch series.

Preparing for the upgrade

Before you upgrade software, complete the following tasks:

1.       Log in to the IRF fabric through Telnet or the console port. (Details not shown.)

2.       Identify the number of IRF members, each member switch's role, and IRF member ID.

<Sysname> display irf

MemberID   Role   Priority  CPU-Mac         Description

 *+1      Master  5         0023-8927-afdc  ---

   2      Standby 1         0023-8927-af43  ---

--------------------------------------------------

 * indicates the device is the master.

 + indicates the device through which the user logs in.

 The Bridge MAC of the IRF is: 0023-8927-afdb

 Auto upgrade                : no

 Mac persistent              : 6 min

 Domain ID                   : 0 

3.       Verify that each IRF member switch has sufficient storage space for the upgrade images.

4.       Compare the free flash space of each member switch with the size of the software file to load. If the space is sufficient, start the upgrade process. If not, go to the next step.

5.       Delete unused files in the flash memory to free space:

# Delete unused files from the flash memory of the master switch.

<Sysname> delete /unreserved flash:/backup.bin

The file cannot be restored. Delete flash:/backup.bin?[Y/N]:y

Deleting the file permanently will take a long time. Please wait...

Deleting file flash:/backup.bin...Done.

# Delete unused files from the flash memory of the subordinate switch.

<Sysname> delete /unreserved slot2#flash:/backup.bin

The file cannot be restored. Delete slot2#flash:/backup.bin?[Y/N]:y

Deleting the file permanently will take a long time. Please wait...

Deleting file slot2#flash:/backup.bin...Done.

Downloading software images to the master switch

Before you start upgrading software images packages, make sure you have downloaded the upgrading software files to the root directory in flash memory. This section describes downloading an .ipe software file as an example.

The following are ways to download, upload, or copy files to the master switch:

·         FTP download from a server

·         FTP upload from a client

·         TFTP download from a server

Prerequisites

If FTP or TFTP is used, the IRF fabric and the PC working as the FTP/TFTP server or FTP client can reach each other.

Prepare the FTP server or TFTP server program yourself for the PC. The switch series does not come with these software programs.

FTP download from a server

You can use the switch as an FTP client to download files from an FTP server.

To download a file from an FTP server, for example, the server at 10.10.110.1:

1.       Run an FTP server program on the server, configure an FTP username and password, specify the working directory and copy the file, for example, newest.ipe, to the directory.

2.       Execute the ftp command in user view on the IRF fabric to access the FTP server.

<Sysname> ftp 10.10.110.1

Press CTRL+C to abort

Connected to 10.10.110.1(10.10.110.1).

221 Server closing.

FTP upload from a client

You can use the IRF fabric as an FTP server and upload files from a client to the IRF fabric.

To FTP upload a file from a client:

On the IRF fabric:

1.       Enable FTP server.

<Sysname> system-view

[Sysname] ftp server enable

2.       Configure a local FTP user account:

# Create the user account.

[Sysname] local-user abc

# Set its password and specify the FTP service.

[Sysname-luser-manage-abc] password simple pwd

[Sysname-luser-manage-abc] service-type ftp

# Assign the network-admin user role to the user account for uploading file to the working directory of the server.

[Sysname-luser-manage-abc] authorization-attribute user-role network-admin

[Sysname-luser-manage-abc] quit

[Sysname] quit

On the PC:

1.       Log in to the IRF fabric (the FTP server) in FTP mode.

c:\> ftp 1.1.1.1

Connected to 1.1.1.1.

220 FTP service ready.

User(1.1.1.1:(none)):abc                              

331 Password required for abc.

Password:                                             

230 User logged in.

2.       Enable the binary file transfer mode.

ftp> binary

200 TYPE is now 8-bit binary.

3.       Upload the file (for example, newest.ipe) to the root directory of the flash memory on the master switch.

ftp> put newest.ipe

200 PORT command successful

150 Connecting to port 10002

226 File successfully transferred

ftp: 32133120 bytes sent in 64.58 secs (497.60 Kbytes/sec).

TFTP download from a server

To download a file from a TFTP server, for example, the server at 10.10.110.1:

1.       Run a TFTP server program on the server, specify the working directory, and copy the file, for example, newest.ipe, to the directory.

2.       On the IRF fabric, execute the tftp command in user view to download the file to the root directory of the flash memory on the master switch.

<Sysname> tftp 10.10.110.1 get newest.ipe

Press CTRL+C to abort.

Upgrading the software images

To upgrade the software images:

1.       Specify the upgrade image file (newest.ipe in this example) used at the next startup for the master switch, and assign the M attribute to the boot and system images in the file.

<Sysname> boot-loader file flash:/newest.ipe slot 1 main

Verifying the file flash:/newest.ipe on slot 1......Done.                                            

Images in IPE:                                                                 

  boot.bin                                             

  system.bin                                          

This command will set the main startup software images. Continue? [Y/N]:y      

Add images to slot 1.                                                     

Decompressing file boot.bin to flash:/boot.bin....................Done.        

Decompressing file system.bin to flash:/system.bin................Done.        

Verifying the file flash:/boot.bin on slot 1...Done.

Verifying the file flash:/system.bin on slot 1............Done.         

The images that have passed all examinations will be used as the main startup software images at the next reboot on slot 1.

2.       Specify the upgrade image file as the main startup image file for each subordinate switch. This example uses IRF member 2. (The subordinate switches will automatically copy the file to the root directory of their flash memories.)

<Sysname> boot-loader file flash:/newest.ipe slot 2 main

Verifying the file flash:/newest.ipe on slot 2......Done.

Images in IPE:                                                                  

  boot.bin                                            

  system.bin                                          

This command will set the main startup software images. Continue? [Y/N]:y      

Add images to slot 2.                                                      

Decompressing file boot.bin to flash:/boot.bin....................Done.        

Decompressing file system.bin to flash:/system.bin................Done.        

Verifying the file flash:/boot.bin on slot 2...Done.

Verifying the file flash:/system.bin on slot 2.........Done.        

The images that have passed all examinations will be used as the main startup software images at the next reboot on slot 2.

3.       Enable the software auto-update function.

<Sysname> system-view

[Sysname] irf auto-update enable

[Sysname] quit

This function checks the software versions of member switches for inconsistency with the master switch. If a subordinate switch is using a different software version than the master, the function propagates the current software images of the master to the subordinate as main startup images. The function prevents software version inconsistency from causing the IRF setup failure.

4.       Save the current configuration in any view to prevent data loss.

<Sysname> save

The current configuration will be written to the device. Are you sure? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait.................

Saved the current configuration to mainboard device successfully.

Slot 2:

Save next configuration file successfully.

5.       Reboot the IRF fabric to complete the upgrade.

<Sysname> reboot

Start to check configuration with next startup configuration file, please wait.

........DONE!

This command will reboot the device. Continue? [Y/N]:y

 Now rebooting, please wait...

The system automatically loads the .bin boot and system images in the .ipe file and sets them as the startup software images.

6.       Execute the display version command in any view to verify that the current main software images have been updated (details not shown).

Upgrading from the Boot menu

In this approach, you must access the Boot menu of each member switch to upgrade their software one by one. If you are upgrading software images for an IRF fabric, using the CLI is a better choice.

Prerequisites

Make sure the prerequisites are met before you start upgrading software from the Boot menu.

Setting up the upgrade environment

1.       Use a console cable to connect the console terminal (for example, a PC) to the console port on the switch.

2.       Connect the Ethernet port on the switch to the file server.

3.       Run a terminal emulator program on the console terminal and set the following terminal settings:

¡  Bits per second—9,600

¡  Data bits—8

¡  Parity—None

¡  Stop bits—1

¡  Flow control—None

¡  Emulation—VT100

Preparing for the TFTP or FTP transfer

To use TFTP or FTP:

·         Run a TFTP or FTP server program on the file server or the console terminal.

·         Copy the upgrade file to the file server.

·         Correctly set the working directory on the TFTP or FTP server.

·         Make sure the file server and the switch can reach each other.

Verifying that sufficient storage space is available

When you upgrade software, make sure each member switch has sufficient free storage space for the upgrade file, as shown in Table 4.

Table 4 Minimum free storage space requirements

If no sufficient space is available, delete unused files.

Scheduling the upgrade time

During the upgrade, the switch cannot provide any services. You must make sure the upgrade has a minimal impact on the network services.

Software Upgrading via Ethernet Interface (FTP/TFTP)

Software Upgrading via TFTP

Introduction to TFTP

TFTP (trivial file transfer protocol) is a type of simple file transfer protocol in the TCP/IP protocol suite that applies between clients and servers. TFTP is normally realized on the UDP basis to provide unreliable data transfer service.

TFTP upgrading procedure

Step 1: Select an Ethernet interface for downloading on the S5136S_EI. Connect the switch to the PC (where the upgrading file is located) via the interface. At the same time, you should connect the switch to a PC via the console port (The PC should be the same as the PC where the upgrading file is located).

Step 2: Run the TFTP server program on the PC connected with the Ethernet interface for upgrading, and specify the file path of the upgrading program.

Step 3: Run the terminal emulation program on the PC connected to the Console port, and boot the switch to access the Boot menu.

Step 4: Enter 1 in the Boot menu. Press <Enter> and the system will access the download program menu.

Please set application file download protocol parameter:

1. Set TFTP protocol parameter

2. Set FTP protocol parameter

3. Set XMODEM protocol parameter

0. Return to boot menu

Enter your choice(0-3):1

Software Upgrading via FTP

Introduction to FTP

Through the Ethernet port, the S5136S_EI can serve as an FTP server or client. It provides another means to download the system program and configure the files. In the following description we assume that the S5136S_EI serves as an FTP client.

FTP upgrading procedure

Step 1: Select an Ethernet interface for downloading on the S5136S_EI. Connect the switch to the PC (where the upgrading file is located and whose IP address should be known) via the interface. At the same time, you should connect the switch to a PC via the Console port (the PC should be the same as the PC where the upgrading file is located).

Step 2: Run the FTP server program on the PC connected to the Ethernet interface for upgrading, and specify the file path of the upgrading program.

Step 3: Run the terminal emulation program on the PC connected to the Console port, and boot the switch to access the Boot menu.

Step 4: Enter 1 in the Boot menu. Press <Enter> and the system will access the download program menu.

Please set application file download protocol parameter:

1. Set TFTP protocol parameter

2. Set FTP protocol parameter

3. Set XMODEM protocol parameter

0. Return to boot menu

Enter your choice(0-3):2

Step 5: Enter 2 in the download program menu. Select FTP for the software upgrading. Press <Enter> and the screen will display the following information:

Load File Name     : app.bin

Server IP Address  :192.168.1.132

Local IP Address   :192.168.1.122

FTP User Name      : s4000

FTP User Password  : s4000

Step 6: Complete the relevant information based on the actual requirements and press <Enter>. The screen will display the following information:

Are you sure to download file to flash? Yes or No(Y/N):

Step 7: Enter Y and the system starts downloading the file. Enter N and the system will return to Boot menu. Take the first case as an example. Enter Y and press <Enter>, the system begins downloading programs. After the downloading is completed, the system starts write-flash operation. Upon completion of this operation, the file attribute should be set.
