I encountered the Unable to Verify Update Package signature issue while trying to upgrade the Dell PowerEdge R430 Server IDRAC. We can encounter this error when attempting to update an iDRAC when jumping up too many versions.

Summary: iDRAC update fails with the following error RED007: Unable to verify Update Package signature. Due to a change to the digital signature, Workaround must be used to complete the update. This is most probably due to the existing iDRAC setup lacking the required information about newer security (certificate) information for the much newer update installer.

A confirmed fix is to apply earlier updates to/for the iDRAC in a more step-wise manner: For instance, if the card is listed as version 2.2x.(etc), apply the update to 2.40.40.40 then 2.5x, etc. up to the latest update. It is often possible to skip one version, but as always, proceed with due care & caution.

How to Fix Unable to Verify Update Package signature

Resolution: The iDRAC7 and iDRAC8 Dell Update Packages (DUP) no longer carry SHA-1 digital signatures. This DUP change was introduced in iDRAC firmware 2.61.60.60 and later. iDRAC7 and iDRAC8 version 2.40.40.40 or later added support to verify the SHA256 signatures. iDRAC must be running one of the following versions to support SHA-256 DUP payloads through Out of Band updates.

In this case, I’m going to upgrade from the 2.21.21.21 version to the final 2.80.80.80, A00 version in a step-wise manner.

1. Go to the Dell Product Support page and search IDRAC update by your Service Tag of your Server and download the IDRAC and Lifecycle controller update.
2. Login to your IDRAC through the web interface using the IDRAC IP address.
3. Expand IDRAC Settings.
4. Click Update and Rollback.
5. On the Update table, select the download IDRAC and Lifecycle Controller update then click Upload.
6. Once the package is successfully uploaded, tick the checkbox of the uploaded file and click Install.
   • Note: I’ve updated the IDRAC and Lifecycle Controller on a Dell R430 Server in three step-wise manner from 2015 to 2021 versions.

7. Check the Job Queue to see the results. If you find a failed result, try with a lower version.

The final result should be successful. Refresh the page and log in to IDRAC again.

A short guide to installing Windows Server on SD Car for Cisco UCS Servers. In this lab, I demonstrate it on Cisco UCS 220 M4. The method works fin for every UCS servers.

Before booting your UCS Server, check the Cisco FlexFlash section via CIMC to make sure the Server recognized the SD card.

I’ve mounted a Samsung Evo SD Card instead of dedicated Cisco SD Card.

Install Windows Server on Cisco UCS SD Card

1. Boot the UCS Server with Windows Server Bootable USB Flash.

2. In the Windows Setup press Shift+F10 to open the command prompt.

3. Type the diskpart and press enters then partition the Cisco UCS SD card for Windows Installation with below diskpart command.

list disk
Select disk 4
clean
format quick fs=ntfs label=System
assign letter=C
active
exit

Now the SD Card is partitioned and ready for deploying Windows Server.

4. Run the Windows image file using the below command from the bootable USB.

X:\source>dism.exe /Apply-Image /ImageFile:d:\sources\install.wim /index:2 /ApplyDir:c:\

Note: the D drive is my Bootable USB which contains the Windows Server sources contents.

5. Finally, edit the Windows Server boot manager to force the system to boot via drive C.

bootsect /nt60 C: /force /mbr<br>
bcdboot C:\Windows /s C:

6. Done. Restart your UCS Server and it will boot up via SD card.
