Firmware Downgrade Options

[Gaisu]

Hello,

When you try to downgrade a firmware using SUM you get the following options:

- Downgrade Firmware & Software

- Downgrade & Rewrite  Firmware & Software 

What is the difference between downgrade and rewrite?

What is meant by software here?

Thanks

Hello ,

What is the difference between downgrade and rewrite?

Downgrade means : Lower version from the current version installed 

Rewrite means : Overwrite the firmware 

Software means: There are so many software listed in the proliant server. That is why they have mentioned software.

Thanks

Hi,

Software refers to : Drivers, HPE Utilities and HPE Agents that was included in the SPP Package.

Hello,

The term 'software' in SUM (or SPP) refers to HPE Softwares, which are the utilities and applications released by HPE. These are released to enable specific functionalities, for example: the Smart Storage Administrator for the RAID Controllers OR SMH that provides users to  be able to monitor the server from the host OS.

Hi 

Downgrade will allow you to downgrade the firmware/software from the Higer Version to lower versions.
Whereas Rewrite will allow you to upgrade/downgrade the firmware/software even if the server has same version is in the package. (Eg: If a component is already at v2.33 and if the SPP package has v2.33, it will rewrite this again on the component)

What is the procedure to downgrade the HBA firmware: HPE SN1000Q 16GB Dual Port PCIe Fibre Channel Host Bus Adapter?

Hi,

You can use "Force" option to downgrade the Firmware either online or offline mode.  

> Online : Based on OS, use the file.

> Offline : SPP.iso image. 

Note : HPE does not recommend downgrading firmware until and unless there is a need. Please make the downgrade is required and then proceed accordingly. 

The following link talks about System ROM, however, it can be used only for reference: Title: HP ProLiant Server Series - Upgrading or Downgrading System ROM Using Online and Offline Methods : https://support.hpe.com/hpesc/public/docDisplay?docId=mmr_kc-0113956   Moderator [above link is no longer valid, please visit https://support.hpe.com/connect/s/  to find the latest info ]
