Using The Emergency Shell; Managing The File System - HP 12500 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 startup boot image
is OK but the startup system image or any startup 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 "Upgrading software", "Performing an ISSU by using issu
series commands", or "Performing an ISSU by using install series commands." This chapter describes
how to get and load the system image in emergency shell mode.
If the device has two MPUs, the two MPUs start up independently. If one MPU enters emergency shell
mode, log in to that MPU through its console port to load a system image for it.
For more information about software images, see "Upgrading software." For more information about
how to log in through the console port, see "Logging in through the console port for the first device
access."

Managing the file system

The emergency shell provides some basic file system management commands for managing the files on
the device's storage media. You can use these commands to manage the file system.
IMPORTANT:
A file deleted by using the delete command cannot be restored.
