I have a few questions on SLES12 multipath io scheduler

On SLES11 there was a yast kernel settings where default io scheduler could be set. This is missing on SLES12. IS there somewhere else this can be set? I know grub bootloader can have this forced on boot, but that seems a step back in configuration options

If I cat on the sys/block/dm-x/queue/scheduler it shows as none, where on SLES11 it would provide the current io scheduler set and it could be changed if required. If this has been changed in SLES12, where do we now view and set io scheduler for multipath and lvm devices?
