3. The goal of the calculation process is to ensure that all parameters end up in
the valid ranges specified earlier in this section. Throughout the calculation,
the total number of blocks should remain constant or as close to the original
value without exceeding it. This is achieved by dividing one value (e.g.
cylinders) by the same amount as one of the other values (e.g. heads) is
multiplied. In this example, we will divide the number of cylinders and
multiply the number of heads by the same value: 3. This results in the
following values:
24533 cylinders
60 heads
169 sectors per track.
4. At this point, allocate the alternate cylinders (2) from the total number of
cylinders to get the following values:
24531 data cylinders
2 alternate cylinders
60 heads
169 sectors per track
Write down the above data and proceed with the next step.
5. Using the format utility, reconfigure your storagesets logical geometry.
- From the main menu, select the storageset
- From the type menu, select other
- Enter the new number of data cylinders, heads and sectors when
prompted. Hit return, to take the default, for all other questions.
- Use the partition command to create the desired partition table layout.
- Use the label command to write the new geometry to the storageset.
Upon completing the above process, you will now be able to use the newfs
command to create filesystems on the partitions you have created.
