getfw - Error: Invalid HUU ISO image

philipp.zenz

Hi guys,

 

I´ve got an problem with the getfw tool to export the CIMC and BIOS Firmware.

 

Steps: (Linux)

- Download ISO from Cisco

- Mount ISO and get the getfw tool

- run as root -> ./getfw -s <path>ucs-c220m5-huu-4.1.1d.iso -d <path>

- get the error message -> "Error: Invalid HUU ISO image" (run as root!)

 

What I´ve tried:

- Other Computer (always Ubuntu)

- Other HUU ISO Image

 

 

Anyone got an idea?

 

ty

Philipp

This Decryption failed is due to an underlying library (openssl I think) version on Ubuntu 20.04.

A fresh Ubuntu 16.04 and was able to complete the extraction:

sttardy@sttardy-virtual-machine:~$ sudo mkdir /mnt/c220
[sudo] password for sttardy:
sttardy@sttardy-virtual-machine:~$ sudo mount ucs-c220m4-huu-4.1.2b.iso /mnt/c220
mount: /dev/loop0 is write-protected, mounting read-only
sttardy@sttardy-virtual-machine:~$ sudo /mnt/c220/GETFW/getfw -s ucs-c220m4-huu-4.1.2b.iso -d .

FW/s available at './ucs-c220m4-huu-4.1.2b'
sttardy@sttardy-virtual-machine:~$ ls -l ucs-c220m4-huu-4.1.2b/*

Hope that helps.

4.1 era firmware fortunately is not encrypted (no need for getfw tool).  You can download the various component firmware files from their respectively named folders.

 

Kirk..

Seems to be wrong.

I´ve mounted the 4.1 ISO and there are no files - just the getfw

I´ve posted the wrong ISO - sorry.

It´s an M4 - ucs-c220m4-huu-4.1.2b.iso 

There are no files if I mount the image.

Hello Philipp.zenz

Have you checked the size of the ISO you download, and the md5 or sha256 chipher from Cisco to check if the ISO are complete?

For your ISO download, ucs-c220m4-huu-4.1.2b.iso just keep your mouse over the download link for MD5 or Sha256.

MD5:474fcd6f670a6423fa46448c4a378d56 (not secure, but roots out failed downloads or copy operations)

Sha256: d0156e2e13c9b26b7f273a392a89c2274346136acf7618b509f426907a70d67166899f19cea784f456aa26b1a59e7f90bd80ccf0d97e4e48c4f4921ed1f4dae9 

For linux you use this operator for MD5 or sha256.
sha256sum /filepath/filename or md5sum /filepath/filename

For windows use Powershell, Get-Filehash -Algorithm Sha512 c:\folder\filename  (change the -Algorithm to md5 or other if you need this).

How to mount a ISO i would run a seach on ubuntu forums.

Why couldnt cisco just upload the needed files - that drives me nuts.

I just need a Firmware file and could try things for hours.

 

 

Same issue I am having now that I have a windows 10 Linux subsystem and all the components installed, I get an Invalid HUU ISO image for the c220m4 image file.

 

thats drives me nuts

No one got an idea?

Kirk already answered you that with HUU 4.1 these files are no longer encrypted, so no need to go through the ./getfw process.

I'm on a Mac and downloaded file ucs-c220m5-huu-4.1.1d.iso.

Double clicked ucs-c220m5-huu-4.1.1d.iso to mount the image:

 % ls /Volumes/ucs-c220m5-huu-1/firmware/{bios,cimc}
/Volumes/ucs-c220m5-huu-1/firmware/bios:
bios.cap

/Volumes/ucs-c220m5-huu-1/firmware/cimc:
cimc.bin

That's it, the files are there.

 

 

Hope that helps.

Hi Steven,

for M5 images yes - thats correct.

But not for M4 images

 

Image ucs-c220m4-huu-4.1.2b.iso:

There are still encrpted files - dont know why cisco is always that complicated.

Posted the steps I used to get these files last month on another thread:

https://community.cisco.com/t5/unified-computing-system/how-to-clear-cimc-password-on-ucs-220m4-server/td-p/3003373

 

Are you unable to follow the directions?

Do you get any errors?
What Linux OS are you using (I used a CentOS 7 VM)?

Hi Steven!

 

I´ve already tried it a several times - same error.

 

1)

philipp@philipp-VirtualBox:~$ sudo mount Downloads/ucs-c220m4-huu-4.1.2b.iso /mnt/lol
mount: /mnt/lol: WARNING: source write-protected, mounted read-only.

2) 

philipp@philipp-VirtualBox:/mnt/lol$ GETFW/getfw -s /home/philipp/Downloads/ucs-c220m4-huu-4.1.2b.iso -d /opt/fips/

Error: Extraction Failed

With sudo:

philipp@philipp-VirtualBox:/mnt/lol$ sudo GETFW/getfw -s /home/philipp/Downloads/ucs-c220m4-huu-4.1.2b.iso -d /opt/fips/

Decryption failed

 

Using Ubuntu 20.04

Hi Steven,

thank you! 

Ubuntu 16.04 worked for me.
