In the last 3 months or so, I've been called into 3 locations that had a 'server' (all Dells, 1 was a poweredge server, 1 was a precision workstation and 1 was a dimension desktop) that WAS running RAID 1 on the motherboard but the 1st drive failed some time ago (and the system kept running) and now the 2nd drive failed and the system is dead.
I guess this is a good example of the need for managed services?
What should indicate a hard drive has failed? I know at reboot, on the desktops, you see the Intel RAID config screen and the status might be 'degraded' as an indication there's a problem.
But other than reboots, how would / should the users or system maintainers learn of a failed hard drive in a RAID 1 configuration?
Lights on the drive tray? Errors in the event log?
How (if there is any way) do you simulate a hard drive failure to test this process? Just pull the power cord on one of the drives?
