Getting errors when running sfdisk to create partitions using sectors

Issue

• As part of the SAN provisioning, we create partitions using sfdisk using the units of 'sectors'. for large disks (19GB), the script works fine. For smaller disks (5.6GB), it fails and reports discrepancies between the C/H/S geometry.

[root@hostname ~]# for L in $( < l.txt ); do  echo "1,,L" | sfdisk -L -uS /dev/mapper/$L; done
