    Thanks for the response Tim. Srry about the mistypes. I meant to say a "hot swap replacement" Im not certain the procedure to remove the defintions from the system that you referenced. I hope you can explain that further. More details on the storage center... IBM DS400 1700 2RD. Connecte vis fiber to my BladeCenter. The current configuration has one controller managing two storage arrays. Both arrays comprised of 4 x 146GB hard rives. It has been that way since I joined the company. The second controller has always had a failed status. I hope this helps. I not very familiar with the setup of such storage arrays. I included a pic and a screenshot from ServeRaid Manager. Let me know what you can, thanks much

    I reply to a response you posted to assist me with a situation with my storage center IBM DS400. Im new to FixYa so I just wanted to confirm that you got my reply. Thanks for the response.

  • Dwayne Sep 14, 2010

    Thanks again! I can tell Im working with a brain here. I didnt try a power down reset since the swap. There are two lit LEDs on the back of the new controller, the 'cache dirty' and the 'controller not ready' both are amber. I read up on what both of them meant but didnt find a fix. It was not a brand new controller. Didnt want to foot the high costs for new :) One half of the array is my live exchange server so a possible shut down wont happen til teh weekend. Any suggestions til then. I'll work on sending some high def pics til then lol

    IBM Total Storage DS400 I did a hot swap replacement of a failed controller... The IBM ServeRaid Managment tool still displays the same failed status on the controller. I also did a restart of the controller with the ServeRaid tool. There are two lit LEDs on the back of the replacement controller, the 'cache dirty' and the 'controller not ready' both are amber. Current config has two arrays, both comprised of 4 x 136GB drives each. One of the arrays is store location of my exchange server. The other is spare. The working controller has been managing both arrays since I joined the company (3 years). Any Ideas on what else I can do to activate or initiallize the controller. I just signed up to FixYa so I hope the experts here can help Thanks much! If you need screen shots or anything further let me know.

    Thanks I'll try it this or tomorrow evening

  • Dwayne Sep 21, 2010

    tbreeze, had a question. I usually power down the server that uses the storage array when I shutdown and restart the enclosure. Is that necessary.

  • Dwayne Oct 01, 2010

    Hi, thanks for the response. I did the full system reboot but unfortunately it still seem to not recognize and activate the replacement controller either. I have the ServerRaid Manager up and Im im not certain what all "safe" options are available through it. If you are familiar with it please offer any suggestion that you can. I was wondering how safe it woudl be to swap the controllers as see what happens. Im a little timid b/c one of the two arrays is my MS Exchange data store.

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:
IBM Total Storage DS400I just did a ot sway replacement of a failed controller.... IBM ServeRaid mgmt displays the same same failed controller status.


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.
Thanks Tim

    Yup I got the reply, hmm, ok that makes a little more sense in someways, but is strange in others. If it is in fact the controller backplane that you swapped it should recognize that without much issue. Have you tried a full rest of the DS400 since swapping? Also, do the lights still indicate failed on the actual controller? Was it a brand new part swap-out from IBM?

    Let me know these things and we can keep going, thanks for the pictures, that's really slick, I think you're the first person I've ever seen post pictures that were helpful! :)

    Tim Grayson Sep 14, 2010

    Hmm, cache dirty eh? That's peculiar indeed. Was that light lit up on the previous controller that you just replaced? Definitely take some more pics if you can, and if you can email me that screenshot that you took, along with any other screenshots you may think would be useful, over to me at microtechftp@yahoo.com ? It is too small to see exactly what's going on in that picture.

    Thanks!
    Tim

  • Dwayne Sep 15, 2010

    I beleive the same lights were lit of the last controller but Im not certain. I'll shoot a few other pics to your email in a minute

    Hey there, I never heard back from you, or if I did I never noticed the message, did you try resetting it?

Ooh, ooh, I know this one. Is it an x346?

Did you also get "error 2807-01 Controller Onboard detected an internal error error 2200
CPPRHTS1&1 FAIL DATA: 035-253-001-20100309-58-RAID"?

Get a 71P8644. I've had two servers fail identically as above. Solid fixes.

Or use a Search Engine if your server/symptom differ.

Troubleshoot ServeRaid problem on IBM x335 Box


The likelyhood that 2 drives fail at the same time is remote. I would first look to teh controller as the problem. Also, check the power supply. The only common things are the 5V and12V supply.

Problem with new array.


Do you see your new disk in the "Disk Management" window? To get there go to "run", type "compmgmt.msc", then click disk management. If you do see the disks there, then you need to format the disk to a "basic" configuration. If your new disk/volume does not show up there, I would suggest a hard reset on your server whenever possible. I see this issue at times with Windows and newly added storage array logical drives.
