My ILOM firmware version is 1.1.1. I want to update the firmware. I have chosen to update the firmware to Sun Fire X4500 Software 1.5.1. It showed the above error message while doing so. I tried to upgrade to Sun Fire X4500 Software 1.2 . Nothing worked. I had the same problem. I downloaded the patches from the following link
what is the exact file name you are using and how are you attempting to upgrade the ilom? cli or web gui ?
i've found the web gui to be the easiest way to make this happen. connect laptop to box and use SP ip such as https://<sp_ip>. after that its straight forward.
I have tried ilom.X4500-1.1.8.ima and ilom.X4500-2.0.2.5-r37042_42606a.ima as well. But nothing worked. Actually I am accessing it using cli and from a remote computer with root privileges. I did not try serial connection to SP.
I will try to work on it. But if you can please let me know what might be the problem with cli.
