slot in which it is installed and takes up the adjacent disk unit slot to its left For example, if the #4331 is installed in
disk unit slot D02, it takes up disk unit slot D02 and disk unit slot D01.
For HSL attached towers on the iSeries servers, the #4331 is installed in the left-most slot of each five-pack and only
takes up one disk unit position.
