When would you not use the LUN alignment offset feature on the CLARiiON, and would use diskpar.exe instead? The LUN alignment offset feature on the CLARiiON and the diskpar.exe in Windows are both useful for correctly partitioning Windows drives to accommodate the MBR.

A.
When using layered CLARiiON applications as they operate on the Raw LUN and as such would incur disk crossings

B.
When directly attaching a Windows hosts to the CLARiiON, as the LUN alignment offset is only available in AccessLogix

C.
When LUNs are configured on a RAID 1/0 group. The mirrored drive doesn’t accommodate LUN Alignment Offset and requires diskpar.exe

D.
When formatting the windows drive as NTFS, since the MBR is not a factor on NTFS drives
