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
Network configuration
As shown in Figure 1, the two-chassis IRF fabric and the TFTP server can reach each other. 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.
Restrictions and guidelines
When you patch software, follow these restrictions and guidelines:
· To install an image, you must begin with the master. To upgrade an image, you must begin with a subordinate device.
· 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 on the master.
<Sysname> tftp 2.2.2.2 get SYSTEM-R7577P01H01.bin
