    Does Intel RST recovery mode have a disk size limitation?

    PWoda

      I'm running WES2009 which uses Intel RST 10.1.0.1008.

       

      The driver refuses to create a recovery mode array with two 1,5 TB drives. RAID1 works okay.

       

      Is there some limitation?

          Intel® Rapid Recovery should work since both drives have the same capacity; however, we strongly suggest using a normal version of Windows* 7, which is fully supported. You may also want to provide more information, such as a copy of the System Report (from Intel® Rapid Storage Technology, click Help, System Report, Save).

            The machine is an industrial computer and changing the OS is not an option.

             

            I will try to provide additional info.

             

            However, I have found this: Re: ERROR: Recovery Volumes must contain a disk < 1.3TB, which seems related to my problem.

              You can see that the array is initializing with the 1,5 TB drives. I had a recovery array of 2 500 GB drives, replaced the recovery drive with 1,5 TB, rebuilt the array, replaced the master drive with 1,5 TB, rebuilt the array, then I picked increase size to 1,5 TB which triggered the initialization. This caused three errors in the Application Event Log: "IAStorUtil.StorageAction.VolumeModify action failed:  BadVolumeOrArrayStatus". When the initialization is finished I wonder if the array will be functional.

               

              Any help will be appreciated.

                Let me know if it gives a pop up error message when the process completes and the Intel® Chipset model.

                  The array seems to be working correctly, no popups. I can also run verification, which completes without problems.

                   

                  According to the datasheet specs: System Chipset Intel GS45 + ICH9-M.

                   

                  I guess the next test would be to try to recreate the array with 1,5 TB drives, which failed before.

                   

                  Current questions:

                  - is this limitation hardcoded in the driver software (can be removed by updating the driver) or is it a hardware limitation of the controller?

                  - is creating a 1,5 TB recovery array by resizing a smaller one a safe workaround?

                    I did not find anything specifically related to your issue in the release notes but you may try Intel® Rapid Storage Technology 11.7, which seems to be the latest version for an Intel® 4 Series Chipset. Updating the RAID Option-ROM may also help, but you may need to check with the system/motherboard manufacturer if there is such change within a BIOS update.

                    I will try to find more information.

                      I grabbed a different machine, it's a newer model which supports Windows Embedded Standard 7 and has an Intel QM77 chipset (OS not installed yet). Using the Option ROM menu, the same error occurs, this time with two 2 TB drives:

                        Based on the picture we can tell that this is either a RAID option ROM or a SATA controller limitation. This is not a driver issue since the message is showing up in the RAID BIOS (and you have not installed the operating system).

                         

                        Besides that, we can see the same message in two systems with different Intel® Chipsets and option ROM versions (8.8.0.1009 and 11.0.0.1339). Currently this is also found in a more recent Intel® Rapid Storage Technology version (12.x). At this time we have no information indicating if this limitation will be changed in the future.

                         

                        I am sorry for the inconvenience.
