I have an Adaptec 1430SA RAID (HostRAID) card with a 4x 250GB total 500GB RAID10 array provisioned and reporting in the Adaptec BIOS as optimal and healthy.
I am trying to access it using an Ubuntu install/live CD (old at version 11 but thats what I had available at the time) with the intent of using dd to clone the array onto another non-RAID disk.
However, I can't seem to see the array device - I get the individual disks making up the array detected as sgX on /dev/sdX devices, and I get a message from dmraid saying "wrong # of devices in RAID set". I get a device dm-2 for the array in dmraid however, it's only 250GB.
Should I believe the RAID bios at boot up or Ubuntu dmraid as to the state of the array?
If the Array is actually healthy how do I get access to the full 500GB of the array so that I can recover the data (using dd to the spare disk)
Thanks
