  • Perc 3/DI issues on a PowerEdge 2550

    Question: Here is the situation.
    I currently have a PE2550 with four drives in it

    On container #0 I have a mirror setup with drives 0 and 1

    On container #1 I have a mirror setup with drives 2 and 3

    A few weeks ago we had an issue were drives 2 and 3 went offline. Didnt show any lights or nothing. So I figured it may have been the backplane so I ordered a new one and installed it. The drives came back online. About a week after this I had looked at array manager and it showed that the raid was degraded on container #1.

    So I rebooted the server and went into the SCSI utility and it didn't show the second drive in the container #1. So I added the drive and rebuilt the RAID. Whenever I would reboot this server it would rebuild the RAID on container#1. Dell told me to upgrade the firmware on the RAID Controller. When I did that I am back to both drives being offline.

    They are suggesting me to replace the power distribution and the cables for the backplane. Any ideas?

    Thanks,
    -Derek

    did they suggest to update the HDD firmware as well?
    also, do those drives work in any other slots on the backplane as they should?

    anyhow, the case mighg be a punctured array, so no matter how much you rebuild it, the error will replicate itself to the drives, and the only way to fix that is to backup the data, and recreate the array from scratch

    anyhow, what you need to do there at the moment, is
    1. update everything
    2. run a full consistency check
    3. export the controller logs, and send them in for Dell to examine

      Well i can't update the drive because it doesn't show power to the drives. I have not tried to switch slots with them. Drives #0 and #1 are the mirror for the OS and they work fine.

        that is the only way to determine whether the drive is at fault, or the backplane (slot). do you only have 4 disk slots in that server?

          Yes it is only 4 slot. I had replaced the backplane. If the drive was at fault would they both not show any lights?

                can you maybe try other disks in those slots?

                  i have some spare ones i could try. the data that is on them will it be erased if it trys to reconfigure the RAID for this server?

                      did the lights come on on the previous backplane? could be a DOA part, really. if it was recently replaced, there might be a basic warranty for the backplane itself

                        No there were no lights on the previous backplane.

                          in that case you have three options:
                          1. not a backplane issue
                          2. DOA backplane sent out
                          3. could more than just the backplane

                          if I were you, I'd start considering upgrading to a 9G or 10G server really. 2550 is ancient

                            Dell is sending me these parts today.

                            1 1E734 Assembly,Printed Wiring Assembly,Daughterboard P2550
                            1 02GEF Kit, Cable,Power,PSDB,P2550
                            1 31VUK Cable Assembly,SMB,2X4 Planar Panel,Poweredge 2550


                            So i am going to see if this fixes it. I would love to upgrade to a new server but we don't have the money.
