Using The Emergency Shell; Managing The File System - HP 5920 series Fundamentals Configuration Manual

Using the emergency shell

At startup, the device tries to locate and load the Comware startup software images, which might include
a boot image, a system image, some feature images, and some patch images. If the boot image exists
and can be used but the system image or any feature or patch image is missing or corrupted, the device
enters emergency shell mode.
After the device enters emergency shell mode, you can log in through the console port and get and load
a system image to start the Comware system. After the Comware system is started, you can load feature
images and patch images as described in
series commands", or

it.
