In this post, I would like to share with you a PowerShell script I use to update the iLO firmware version of multiple HPE ProLiant servers
During my research on how to update the firmware version of the iLO of a HPE ProLiant server, I used code from the following web sites:
https://www.vgemba.net/microsoft/powershell/Update-HPE-iLO-Firmware/
https://dailysysadmin.com/KB/Article/4039/update-your-hpe-ilo-device-firmware-using-powershell/
This script uses the HPEiLOCmdLets PowerShell Module, which can be installing using this PowerShell command:
1 | Install-Module -Name HPEiLOCmdLets |
Before running this script (I suggest you try it on 1 server first 
), first update these variables:
- $iLO4_FirmwareVersion
- $iLO4_FirmwareFile
- $iLO5_FirmwareVersion
- $iLO5_FirmwareFile
- $iLO_Range
These should reflect the latest firmware versions and files for the iLO4 (HPE ProLiant Gen8/9) and the iLO5 (HPE ProLiant Gen10).
Variable $iLO_Range must reflect the IP address range of the iLO’s you want to update. If you just want to update 1 iLO, enter the value as ‘10.10.10.50-50’.
The values in the script below are examples only and need to be changed to your environment.

As always, please keep in mind this script is tailored to my environment but can be used as a template for your environment. I do not pretend to be a PowerShell guru and as such my script may not be perfect. I am open to suggestions, though 
If you found this script useful, I’d appreciate it if you leave a comment.
