RAID Level 1-Concatenated (Concatenated mirror)
RAID 1-concatenated is a RAID 1 disk group that spans across more than a
single pair of physical disks. This combines the advantages of concatenation
with the redundancy of RAID 1. No striping is involved in this RAID type.
NOTE: You cannot create a RAID 1-concatenated virtual disk or reconfigure to
RAID 1-concatenated with Storage Management. You can only monitor a RAID 1-
concatenated virtual disk with Storage Management.
