What am I seeing?
An error message that says Volume creation failed appears when you try to create a RAID volume.
How do I fix it if I'm trying to migrate my data to a RAID volume?
You may not have enough unpartitioned space at the end of the existing hard drive to add the RAID information. If possible, decrease the partition size on that hard drive by a few MB, and then try to create the RAID volume again.
What if I'm trying to create a second volume on an array?
The volume you are creating may not be supported in combination with the first volume on the array. Select a volume type and number of hard drives for that volume that are supported, and then try to create the RAID volume again.
