Appendix C Upgrading software

The following information describes how to upgrade software while the router is operating normally or when the router cannot correctly start up.

System software file types

System software images are in .bin format (for example, main.bin) and run at startup. You can set a system software image as a main, backup, or secure image.

At startup, the router always attempts to boot first with the main system software image. If the attempt fails, for example, because the image file is corrupted, the router tries to boot with the backup system software image. If the attempt still fails, the router tries to boot with the secure system software image. If all attempts fail, the router displays a failure message.

Upgrade methods

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

Upgrade method	Remarks
Upgrading from the CLI	· You must reboot the router to complete the upgrade. · This method can interrupt ongoing network services.
Upgrading from the Boot menu	Use this method when the router cannot correctly start up.

Upgrade method

Remarks

Upgrading from the CLI

· You must reboot the router to complete the upgrade.

· This method can interrupt ongoing network services.

Upgrading from the Boot menu

Use this method when the router cannot correctly start up.

Preparing for the upgrade

Verifying device status

Example:

IMPORTANT:

Before you perform an IRF master/subordinate switchover or active/standby MPU switchover, verify that the device is in stable state.

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 :Stable

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 1.

· 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 1 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 Virtual Technologies configuration guide for the H3C S5560X-EI switch series.

Preparing for the upgrade

Before you upgrade software, complete the following tasks:

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

5. 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 2 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

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

IMPORTANT:

Each IRF member switch must have free storage space that is at least two times the size of the upgrade image file.

# Identify the free flash space of the master switch.

7. 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.

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

CAUTION:

· To avoid data loss, do not delete the current configuration file. For information about the current configuration file, use the display startup command.

· The delete /unreserved file-url command deletes a file permanently and the action cannot be undone.

· The delete file-url command moves a file to the recycle bin and the file still occupies storage space. To free the storage space, first execute the undelete command to restore the file, and then execute the delete /unreserved file-url command.

# 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

Trying 10.10.110.1...

Press CTRL+C to abort

226 Transfer complete.

32133120 bytes received in 35 seconds (896. 0 kbyte/s)

ftp> bye

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:

5. Enable FTP server.

<Sysname> system-view

[Sysname] ftp server enable

6. 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:

7. 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.

8. Enable the binary file transfer mode.

ftp> binary

200 TYPE is now 8-bit binary.

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

ftp> put newest.ipe

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:

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

11. 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.

100 30.6M 0 30.6M 0 0 143k 0 --:--:-- 0:03:38 --:--:-- 142k

Upgrading the software images

To upgrade the software images:

12. 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 image file..........Done.

Images in IPE:

boot.bin

system.bin

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

Add images to target slot.

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

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

The images that have passed all examinations will be used as the main startup so

ftware images at the next reboot on slot 1.

13. 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 image file..........Done.

Images in IPE:

boot.bin

system.bin

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

Add images to target slot.

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

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

The images that have passed all examinations will be used as the main startup so

ftware images at the next reboot on slot 2.

14. 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.

15. 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.

16. 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.

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

NOTE:

The system automatically checks the compatibility of the Boot ROM image and the boot and system images during the reboot. If you are prompted that the Boot ROM image in the upgrade image file is different than the current Boot ROM image, upgrade both the basic and extended sections of the Boot ROM image for compatibility. If you choose to not upgrade the Boot ROM image, the system will ask for an upgrade at the next reboot performed by powering on the switch or rebooting from the CLI (promptly or as scheduled). If you fail to make any choice in the required time, the system upgrades the entire Boot ROM image.

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.

TIP:

Upgrading through the Ethernet port is faster than through the console port.

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.

NOTE:

The file server and the configuration terminal can be co-located.

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

IMPORTANT:

For the switch to start up correctly, do not delete the main startup software images when you free storage space before upgrading Boot ROM. On the Boot menu, the main startup software images are marked with an asterisk (*).

When you upgrade software, make sure each member switch has sufficient free storage space for the upgrade file, as shown in Table 6.

Table 6 Minimum free storage space requirements

Upgraded images	Minimum free storage space requirements
Comware images	Two times the size of the Comware upgrade package file.
Boot ROM	Same size as the Boot ROM upgrade image file.

If no sufficient space is available, delete unused files as described in “Managing files from the Boot menu.”

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.

Changing the attribute of software images

Software image attributes include main (M), backup (B), and none (N). System software and boot software can each have multiple none-attribute images but only one main image and one backup image on the switch. You can assign both the M and B attributes to one image. If the M or B attribute you are assigning has been assigned to another image, the assignment removes the attribute from that image. If the removed attribute is the sole attribute of the image, its attribute changes to N.

For example, the system image system.bin has the M attribute and the system image system-update.bin has the B attribute. After you assign the M attribute to system-update.bin, the attribute of system-update.bin changes to M+B and the attribute of system.bin changes to N.

To change the attribute of a system or boot image:

To handle a software upgrade failure:

1. Verify that the software release is compatible with the switch model and the correct file is used.

2. Verify that the software release and the Boot ROM release are compatible. For software and Boot ROM compatibility, see the hardware and software compatibility matrix in the correct release notes.

3. Check the physical ports for a loose or incorrect connection.

4. If you are using the console port for file transfer, check the HyperTerminal settings (including the baud rate and data bits) for any wrong setting.

5. Check the file transfer settings:

¡ If XMODEM is used, you must set the same baud rate for the terminal as for the console port.

¡ If TFTP is used, you must enter the same server IP addresses, file name, and working directory as set on the TFTP server.

¡ If FTP is used, you must enter the same FTP server IP address, source file name, working directory, and FTP username and password as set on the FTP server.

6. Check the FTP or TFTP server for any incorrect setting.

7. Check that the storage device has sufficient space for the upgrade fil e.
