system

format, for example, flash:/startup-system.bin.
feature
feature-package
: Specifies a space-separated list of up to 30 .bin feature image files. Each
feature image file name must be a case-insensitive string of up to 63 characters. In addition, the file

Usage guidelines
If you do not specify upgrade software images, the switch reboots without upgrading software.
If you specify upgrade software images, this command adds the specified images to the main startup
software image list and performs a warm reboot.
Use this command in the following situations:
•
Upgrade Comware images without upgrading the Boot ROM. The warm-reboot method directly
loads and executes Comware software images in the memory instead of booting the Comware
images from the Boot ROM. Compared to upgrading software through the
boot-loader
command, warm reboot reduces the service downtime.
•
Upgrade only a specific image, for example, upgrade only the system image. When you
upgrade feature images through warm reboot, you only need to specify upgrade images for
features you are upgrading. The warm-reboot method replaces the old images for the specific
features instead of overwriting the entire software list as does the
boot-loader
command.
Before you specify startup software image files, save the upgrade files to the root directory of the
flash memory. If the flash memory is partitioned, save the files to the root directory of the first
partition.
This command can upgrade software only between compatible software versions. When the system
executes the command, it verifies the compatibility between the current and upgrade software
versions. If the software versions are incompatible, you must use the reboot method to upgrade the
software from the CLI. For more information about the reboot method for software upgrade, see the
fundamental configuration guide for the switch.
