    32 logical subsystems. To provide integrity checking of data and to allow different operating systems to use the storage unit, IBM formats the disks to a 524-byte sector. The 524-byte sector replaces the traditional 512-byte sector of fixed-block architecture DDMs. The 524-byte sector format requires that you reformat all disks that you are migrating to the storage unit.

    Most LUNs for open-systems hosts are exposed with a 512-byte sector. The IBM AS/400 and iSeries host systems use eight bytes at the start of the sector. UNIX host systems do not use these eight bytes when you attach them to the storage unit.
