Question about IBM TotalStorage DS4700 (181470H) Hard Drive Array
IBM Total Storage DS400 I just did a ot sway replacement of a failed controller.... IBM ServeRaid mgmt displays the same same failed controller status. Current config has two arrays, 4 x 136GB drives each. The working controller has been managing both arrays for some time now. Any Ideas. I just signed up to FixYa so I hope someone may have doen this one before. Thanks
OK, things that may cause this, The MotherBoard has developed a fault. To my mind, It is unlikely that TWO RAID controllers will go "Faulty" simultaneously? You need to test them BOTH to isolate the problem. and see if indeed it is the actual controllers?
What you need to do, is check those RAID controller IN ANOTHER system, and see if they are even functional? IF they are, then this more points to a faulty MB. Also check the Power Supply unit too, I have seen misbehaving PSU's cause RAID Controller problems.
Although they are "Hot Swap" that still doesn't mean that they haven't gone faulty from the motherboard, removal/ insertion?.
Also Check the RAM, if this faults, it may interfere with the controller.

This sounds like the ServeRaid isn't recognizing the new controller, and the software needs to be reset and initialized. A complete system reboot will probably (and hopefully) reset and recognize the replaced controller.
I assume you have a manual, but in case you don't, here's one:
Good luck, and hope this helps.

Hello there, I am a former IBMer that worked with storage arrays all the time, but I am confused on your issue here. I think you may have missed a few characters in your first couple sentences here:

So have you replaced the failed controller? Sometimes you need to remove the definition from the system of the one controller and re-add it for it to recognize, but shouldn't need to.
Let me know some more info and I can definitely help you here.
