Dell 2950 hard drive failure message

Posted on 2007-10-14

We are running two dell PowerEdge 2950's connected to a APC UPS.  The ups went down but the 2950's are connected to commercial power also.

The alarm went off for the ups and the 2950's showed a hard drive failure.  I reset a button on the back and the light on the back went from red to blue to show it was back online again.  Why did this happen and what does it mean for my future reference.

    Assumimg that the UPS is situated between the mains power and the 2950's than a problem with the power that you describe may mean that the UPS is not pwerful enough for the task in hand and when called upon, it could not deliver the power required to keep the 2950's running properly. Check the rating of your UPS and the power requirements of the 2950's and any other attached equipment.

    Have the logs on the server and APC software been reviewed?

    Use the Dell software to check the state of your RAID configuration. If you get the same error that a disk fails again, use the utility to find out what and which disk is bad, then replace it. It is better to replace bad disks when they go bad than wait too long.

    How are these plugged in?

    I am kind of concerned on how these are plugged in.

    The 2950s came with two power supplies. One is for each Processor. When shipped, the servers should have come with a single power cable that is Y-d. That power cable should be plugged into one source of power. If you have one power supply to a processor and your drives, plugged into your UPS and you have the other power supply plugged into commercial power, when your UPS drops, you will still have power to one Processor.
