I have a number of Dell R710s. I have a really annoying behaviour which is when one of them boots it is hanging. They are all connected to an ATEN KVM which I swapped thinking it was my old KVM causing the issue. The hang is clearly being caused by the USB cable from the KVM being plugged in at the time of boot.
I have so far:
- Change the KVM cable
- Change the port the cable is plugged into on the KVM
- Updated the BIOS
- I think I have updated all the firmware’s (e.g. DRAC, etc.).
- Been through the BIOS on one of the working R710 and the hanging R710 and cannot see any obvious configuration differences.
Only difference I have been able to identify is all of the working R710s have a PERC6i raid controllers and the hanging one has a H700.
Has anybody seen this before or have any ideas?
