Item Description

File Type

Specify the type of the next-startup system software image:

Main—Main system software image to be used at the next startup. The main

system software image has higher priority than the backup system software

image at startup.

Installing hotfixes

Hotfixes (called "patches" in this document) repair software defects without requiring a system reboot.

Basic concepts

This section describes the basic patch concepts.

Patch, patch file, and patch package file

A patch fixes certain software defects.
A patch file contains one or more patches. After being loaded from the storage medium to the patch

memory area, each patch is assigned a unique number, which starts from 1. For example, if a patch file

has three patches, they are numbered 1, 2, and 3.
A patch package file contains patch files for multiple modules. It enables you to use one command to
bulk-fix bugs for multiple modules.
