Can RAID 0 volume be deleted and re-added with no data loss?

I have a Dell Precision 690 Workstation with an LSI Integrated RAID controller. I have a 2-disk RAID 0 (what LSI refers to as an IS or Integrated Striping) volume. Recently the motherboard was replaced (and the RAID controller is integrated onto the motherboard). Ever since the motherboard replacement, I get the following error at boot time: Dell SAS 5 Host Bus Adapter BIOS MPTBIOS-6.12.02.00 (2006.12.22) Copyright 2000-2006 LSI Logic Corp. Integrated RAID exception detected: Volume (00:130) is currently in state INACTIVE/OPTIMAL Enter the SAS Configuration Utility to Investigate! I can temporarily resolve this problem by activating the volume in the RAID configuration utility: select SAS1068 RAID properties Manage Virtual Disk Activate Array Y But if the power is disconnected, then the same error recurs on the next boot. I am thinking that if I delete the volume and re-add it, then the problem will go away, but I'm afraid I might lose all my data if I do that. Does anyone know if that's true? Any help appreciated. Thanks, Roger

Thanks. We'll let you know when a new response is added.

Most RAID controllers will wipe the data when you recreate the volume.

In theory you can delete the array and if it is recreated with the disks in the same order the logical volume will remain intact. I would NOT try this without backing up the data on the array before hand. You will probably loose all the data on the array when you delete the array.

    I made a clone of my RAID 0 using knoppix then I went ahead and deleted the array. Sure enough, that lost all the data. Unfortunately, even after recreating the array, the "INACTIVE/OPTIMAL" RAID error continued to occur. Fortunately my system is under warranty. Dell replaced the motherboard and now the RAID error is gone. Roger

    Roger, So if your data is that important why are you keeping it on a RAID-0 volume? Get bigger disks and use RAID-1 G
