2. Calculate the new values for the geometry by dividing the quantity which is
too large by the same amount that is used to multiply one of the other
quantities. Quite often the cylinders count is too large, and the heads count
can be adjusted upward. During this process, ensure that the formula
cylinders x heads x sectors remains constant. In this example, divide the
cylinders count by 2 and multiply the heads count by 2 to get the following
values:
Note that the resulting size is slightly smaller.
3. Delete the unit, so that the storageset can be re-initialized:
HSG80> DELETE D101
4. Initialize the storageset with the new values:
HSG80> INITIALIZE R0 CYLINDERS=37491 HEADS=40
Be sure to use the same additional qualifiers as when the storageset was first
initialized.
5. Add the unit:
HSG80> ADD UNIT D101 R0
At this point, verify that the value is correct with the SHOW command.
Upon completion of the above steps you are able to format the storageset and
create a file system.
