This part:

"but the enumeration of hardware drives starts at 16. So for a controller that
support say 64 logical volumes, only the first (64-16) drives will be

16, and with a HP H241 controller that supports 64 logical volumes only the
first (64-16) drives will be detected. And none of the SES "targets" (one per
drawer in the D6020 enclosure) either since they are listed last...
