3.5.1 Programmable drive capacity Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter list table in the Fibre Channel Interface Manual, part number 100293070. Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indi- cates that the drive shall not change the capacity it is currently formatted to have. A number in the number of blocks field that is less
