Introduction

This document provides software patching examples that use ISSU install commands.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of ISSU.

Example: Patching software in standalone mode

Network configuration

As shown in Figure 1, the device and the TFTP server can reach each other. The device has one active MPU (slot 0) and one standby MPU (slot 1). The MPUs are running boot image BOOT-R7577P01 and system image SYSTEM-R7577P01.

Use patch image file SYSTEM-R7577P01H01.bin to fix bugs without rebooting the device.

Figure 1 Network diagram

 

Restrictions and guidelines

When you patch software, follow these restrictions and guidelines:

·          The first time you install patch images, you must start with the active MPU. For subsequent patch installations, you must start with the standby MPU.

·          The patch image version must match the device model and Comware version. For example, to fix bugs in R7577P01, you must use SYSTEM-R7577P01H01.bin.

Procedures

# Download patch image file SYSTEM-R7577P01H01.bin from the TFTP server to the root directory of the CF card on the active MPU.

<Sysname> tftp 2.2.2.2 get SYSTEM-R7577P01H01.bin

Press CTRL+C to abort.

<Sysname> install activate patch flash:/SYSTEM-R7577P01H01.bin slot 1

This operation maybe take several minutes, please wait.............Done.

The patch images take effect immediately after they are activated.

# For the patch images to take effect after a reboot, commit the software changes.

<Sysname> install commit

Verifying the configuration

# Verify that the patch images have been activated successfully.

Configuration files

The system does not save the commands used in the configuration procedures to a configuration file.

Example: Patching software in IRF mode

Network configuration

As shown in Figure 2, the two-chassis IRF fabric and the TFTP server can reach each other. Each member of the IRF fabric has one active MPU (slot 0) and one standby MPU (slot 1). The IRF members are running boot image BOOT-R7577P01 and system image SYSTEM-R7577P01.

Use patch image file SYSTEM-R7577P01H01.bin to fix bugs without rebooting the members.

Figure 2 Network diagram

 

 

Restrictions and guidelines

When you patch software on an IRF fabric, follow these restrictions and guidelines:

·          To install an image, you must begin with the master. On each member device, you must begin with the active MPU. To upgrade an image, you must begin with a subordinate device. On each member device, you must begin with the standby MPU.

·          The patch image version must match the device model and Comware version. For example, to fix bugs in R7577P01, you must use SYSTEM-R7577P01H01.bin.

Procedures

# Download patch image file SYSTEM-R7577P01H01.bin from the TFTP server to the root directory of the CF card on the global active MPU.

<Sysname> tftp 2.2.2.2 get SYSTEM-R7577P01H01.bin

Press CTRL+C to abort.
