Thanks Stalin,
but what that means: that a partition beginning at the first cylinder is not aligned with the HW stripe size (presumably a power of 2)?

I've asked if the storage team had some special requirement (or suggestion) as far as the first cylinder of the partitions is concerned and I've received a generic reply that I shouldn't bother.

Best regards
