HP 5920 Series Fundamentals Configuration Guide

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 "Upgrading software", "Performing an ISSU by using issu
ser
i
es 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 more than one member exists on the device, each member starts up independently. If one member
enters emergency shell mode, log in to that member through its console port to load a system image for
it.
For more information about software images, see "Upgrading software." F
o
r more information about
how to log in through the console port, see "Logging in through the console port for the first device
acces
s."
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.
• The format command permanently deletes all files and folders from a storage medium, and the deleted
files and folders cannot be restored.
To manage the file system, execute the following commands in user view:
Task Command Remarks
Display files or folders. dir [ /all ] [ file-url ] N/A
Create a folder on a
storage medium.
mkdir directory
The parent folder must already exist. For example, to
create folder flash:/test/mytest, the parent folder test
must already exist on the Flash.
The name for the new folder must be unique in the
parent folder.
Display the current
path.
pwd N/A
Copy a file.
copy fileurl-source
fileurl-dest
N/A
Move a file.
move fileurl-source
fileurl-dest
The destination folder must have enough space for the
file.
