• Redundant-controller RAID configuration
Two volumes (for raid30, raid50, or raid60) or two logical disks (for other RAID levels) will be created with all capacity of
all disks in the RAID enclosure. One volume will be based on two disk groups, so totally there will be four disk groups.
The preferred controller of one volume or logical disk is assgined to controller A and the other is assigned to controller B.
They will be mapped to LUN 0 and LUN 1 of all host ports on both controllers. All other configurations will remain
unchanged, and all RAID parameters will use the default values.
