Question partition a mappered device using multipath

I have installed multipath and I could see all the mapped devices under /dev/mappper/. I could use "fdisk" to do the partition on mappered devices. However, when I use "sfdisk", it doesn't work, and see following error messages. I need to use "sfdisk" for scripting. Help please.

root@localhost:/root> sfdisk -uM /dev/mapper/3600c0ff0000000000a90447c427cdf00
Checking that no-one is using this disk right now ...
BLKRRPART: Invalid argument

This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
Use the --force flag to overrule all checks.

Uhm... I'm confused. What are you trying to do exactly, as the only way I've used the multipath device mapper is via LVM. Tell me more.
