Component Software -
When iDRAC is in a failed state, System Services will report disabled during POST and you will not have access to CTRL-E iDRAC settings menu. You will also be prompted for an iDRAC not responding error at the end of POST.
Can you power off the host, reset the iDRAC and once the iDRAC is back up, launch the iDRAC GUI and verify you can access the GUI with no issues. If this passes, power on the host and verify you have System Services and CTRL-E available.
If you see System Services still disabled but you have access to CTRL-E, go into CTRL-E and enable System Services, save and exit.
Once you see System Services is available and CTRL-E iDRAC menu during POST, can you boot back into the OS and try your update again?
Thanks
