The server was ON prior to admin login to initiate a graceful shut down. This is the last power state of the system. Test the same steps with the AC Power Recovery mode set to Off and see what happens. The system should remain in Off state.
Last week we had a scheduled power outage and a PowerEdge R610 Rev II BIOS 6.4.0 was shutdown from within Windows 2008 R2 cleanly. Power was cut for electrical work and then restored about an hour later. The server then started by itself, I've checked the relevant setting in BIOS and it is set to Last for AC power recovery. Is this normal? The server was shut down when power was cut so my expectation would be that it would remain off until it was manually started, via DRAC or on site. The main issue being is that the power was then cut again, this server was powered down correctly by the UPS software and then back on again when power was restored, which is good to know that worked ok. But the server should have really remained off for the night.
