Hi
This seems like a concurrent update limitation of OA.
Based on my understanding firmware update is two step process:
- Downloading the image, and
- Flashing the image.
While doing firmware update for multiple blades OA will attempt to download firmware for a blade while another download is in progress so there are chances that it may fail since it download the same file everytime before first download complete.
However you can try following:
1. Check if individual blade ilo update works:
e.g:
OA1> update ilo 1 http://<URL>/ilo5_120.bin
OA1> update ilo 2 http://<URL>/ilo5_120.bin
2. Instead of ALL try 4-5 blades at a time.
e.g:
OA1> update ilo 1,2,3,4 http://<URL>/ilo5_120.bin
3 . Update OA to 4.95 (latest firmware) and check.
