Specific Migrating Requirements

The following table lists the disk requirements for a new RAID array for various migrating combinations.

From	To	New Array Disk Requirements
	RAID 0	m > n
		Number of disks in the new array must be greater than the original array.
	RAID 1	m =2, n =1
		RAID 1 array must include two disks, converted from a one disk RAID 0
RAID 0		array.
		m >= 2 x n
	RAID 0+1	Number of RAID 0+1 disks must be equal to or greater than twice the
		number of RAID 0 disks.
	RAID5	m >= n+1
	RAID 0	No additional restrictions.
RAID 1	RAID 1	** Not a valid combination **
	RAID 0+1	No additional restrictions.
	RAID 5	m >= 3
		m >= n2
	RAID 0	Number of RAID 0 disks must be equal to or greater than half the number
		of RAID 0+1 disks.
RAID 0+1	RAID 1	** Not a valid combination **
	RAID 0+1	** Not a valid combination **
	RAID 5	m >= (n/2 + 1)
	RAID 0	m >= n - 1
RAID 5	RAID 1	** Not a valid combination **
	RAID 0+1	m >= 2 x (n -1) ; where m is an even number of disks.
	RAID 5	m >= n
