Christian,
I set up with a new scenario, using UEFI mode, and now it’s normal. Anyway, I think it would be good to investigate why in BIOS mode, that behavior occurs. For this I will detail the situation better, in case you want to investigate this in a test environment.
1 - Dell PowerEdge T440 Server, configured for BIOS Mode
a - installation using the latest installer version “4.4-7 errata 829”
installs fast and everything goes well, but when upgrading to errata 924, no longer boot, it seems to corrupt the grub configuration.
b - I am using Raid 10 via PERC 730P controller
2 - Dell PowerEdge T440 server, configured for UEFI Mode
a - installation using the latest installer version “4.4-7 errata 829”
installs much slower, I believe it took twice the time to complete the installation, but everything went well … and when upgrading to errata 924, there was no problem with the boot, everything is normal.
b - I am using Raid 10 via PERC 730P controller
3 - I have some equipment of the same model, running with BIOS Mode. I am now concerned with updating to errata 924, and losing the boot. That would be terrible for those machines that are in production.
4 - On another Server, another model, which uses Raid via Software, the update to errata 924 also went well.
Do you have any clue as to what that might be, and how to avoid it?
Regards,
Michael Voigt
