This is just to sort the partition numbers in ascending order ready to input to fdisk or cfdisk. Here you take physical track positioning into account when finalizing your design. Unless you get specific information otherwise, you can assume track 0 is the outermost track.
These numbers and letters are then used to update the previous tables, all of which you will find very useful in later maintenance.
In case of disk crash you might find it handy to know what SCSI id belongs to which drive, consider keeping a paper copy of this.
Drive : sda sdb sdc hda hdb hdc ___
Total capacity: | ___ | ___ | ___ | ___ | ___ | ___ | ___
