Pinned topic HS23 hangs on "Connecting Boot Devices and Adapters

‏2013-09-22T18:22:05Z |

Dear Team,

We have number of Blade servers running HS22 and HS23 blades which hang during reboot and takes more than 2 hrs to come to OS.

Have update firmware and removed SAS card but still very slow boot.

And one of the server comes with LSI Adapter Malfunction error

Kindly advice

Ahmar

    The slow boot time is because you have something hammering the SAS fabric.  First, you should remove the blade with the LSI controller malfunction and see if that resolves the issue.  If not, you need to check the SAS ports on the storage modules.  Login to the IO module 3 and 4 and see if there are any active alerts if they are RSMs or if there are any errors if they are NSSMs.  If none of that resolves, try powering down your blades and reseating the DSMs.  It's possible one of the expanders on the DSM is out to lunch and it's hanging the SAS fabric bus.  

    The LSI malfunction is most likely a bad controller.

      Dear Josh,

       

      thanks a lot for your input but unfortunately we have tried three different SAS card and with different  Fw levels. Moreover this is Blade chassis H and has tape library and DS3524 storage connected via SAS switch.

      And we have noticed issue with one of the SAS switch aswell but we updated the firware and it looks stable with no error alert.

      But the there is some SAS ID issue.Pls check the pic

       


      Kindly advice

        The SAS connectivity daughter card on the blade is not the LSI controller.  It provides a path, or highway if you will, to the SAS switch for the blade.  The LSI controller is on the motherboard and handles internal SAS blade drives and any drive connections assigned from the switch.  I would remove the blade that has the malfunction error and see if the boot time improves.  If it does not, than another device is trashing your SAS bus. Run the same command in your attachment from the other SAS switch (if you have one installed in I/O module 4) and see if  there are any ports disabled or in an error state.  

        Again, the SAS connectivity card is not the problem.

            Dear Josh,

            Can you give your inputs for the slow boot for five of our HS23 blade servers having SAS card, its take around 5 hours to boot to UEFI screen.

            Then it loads the OS.

            As we have tried firmware update aswell but no luck.

            But when we remove the SAS card the server boots fine and quickly.

            \Any advice.

            thanks

              Can you provide your firmware levels for both switches and screenshots of the Monitor SAS switch output from both switches?  Most likely, you have a failed drive, switch, or a zoning issue that is causing a conflict and the slow boot times.
