We have some new R420's with cabled HDDs and dual redundant PSUs. If the power to one of the PSUs is cut, the blue power failure and system ID LEDs turn amber as expected. But if power is restored, the LEDs on about 20% of these servers turn blue but the rest stay amber. Power is definitely reaching both PSUs as the transparent handles light up green. All the other Dell servers we have reset their power fail LEDs when redundant power is restored, just not the R420s.
Is there any way I can reset these LEDs to blue on a running server as power cycling them is something I want to avoid doing? I can't find any IPMI command that will do this.
