Abstract:
A method for a redundant array of independent disks (RAID) controller for migrating a RAID level in spanned arrays is disclosed. In one embodiment, a method for a RAID controller for migrating a RAID level in spanned arrays includes receiving a command for a RAID level migration from a first RAID level in spanned arrays to a second RAID level. The method further includes initializing a number of pointers which correspond to a number of the spanned arrays in the first RAID level, and transferring at least one data block of the first RAID level in the spanned arrays using the number of pointers to form the second RAID level.
