    ESRT2 RAID 1 Degraded - new drive in failed state


      I have a server with an S5000PSL system board using ESRT2.

      The server had two 1TB SATA drives in a RAID1 config.

      Drive 0 failed (it was a Seagate 7200.11 drive, one of a run with known issues).


      The system is up and running with the RAID in degraded state - the failed drive is removed.


      BIOS can see the new replacement drive but either in the BIOS RAID configuration utility or the Web RAID configurator, the drive shows up as FAILED Ready to Remove.

      With the replacement drive in this state I cannot get the system to rebuild the RAID.


      The good drive is also one that needs a Seagate firmware upgrade, but I would really like to rebuild the array before I upgrade the controller firmware for the SATA drive.


      Should I clear the RAID configuration and then import the config from the good drive?

      I'm very familiar with Dell PERC and HP Smart array controllers, but the ESRT2 is new to me.  I don't want to make a misstep and blow away the client's data.

      I'm taking a drive clone image of the good drive in any case.

      The server owner has what appear to be good data backups but I don't want to take any unneeded risks.

          In the BIOS configuration utility, select Rebuild, highlight the drive marked as FAIL, press space to select it, and then press F10 to start the rebuild.

            Thanks very much for your answer, which would be correct if the system were functioning properly, but in this case the drive refuses to rebuild.

            The failed drive indicator remains even when we remove the drive.

            At this point I have cleared the RAID configuration and have the server running with the single remaining drive as a single stripe RAID0.  We have cloned the drive and are being very careful with backups.

            The system does not want to recognize any drive plugged into any slot other than slot 1, which makes me suspect the backplane.

            The customer has to complete year-end processing, and I will give them time to do so.

            At that time we will upgrade the firmware for the S5000PSL system board BIOS, the ESRT2 Controller and especially the backplane. Its firmware level is 2.02 and the current version is 2.09.  From what I can see the upgrade is a bit finicky, requiring a flash to 2.05 first then 2.09, and a few calisthenics to get it done properly.

            After we have flashed the firmwares to match the drivers we are already running in the OS, then I will make a new clone of the hard drive, clear the RAID config and set up a new RAID1 array, if the system will recognize a new drive.  If that doesn't work, then I suspect we may have to replace the backplane.


            I'm used to working with servers from another couple of manufacturers and don't have a lot of experience with Intel boxes.  This server is a whitebox server built with Intel components sold to the customer by a local boutique IT shop two years ago.  It's unbranded but Intel is a known major manufacturer.  If I understand correctly the integrated ESRT2 storage controller is by LSI Logic, the same folks who make the integrated RAID controllers used on Dell servers.  I wish there were more information on the backplane, as I have seen backplanes cause similar problems before.


            If I do need to replace it, is the backplane separate from the drive cage or are they one piece with one part number?

            Thanks in advance.

              Which backplane are you using? Did you try the hard drive in another slot, or try to connect it directly to the motherboard using a SATA cable?


              If you need to go for a warranty replacement, take the backplane our of the drive cage. It has it's own part number and serial number printer on a label.


              If you need more information about ESRT2, check the RAID software user's guide.
