Is it possible to change the IO scheduler tunings for Fusion IO devices?

Solution Unverified - Updated -

Issue

  • We have a system with Fusion ioDrive 2 card in that, we would like to have use noop for its IO Scheduler. However, when attempting to access /sys/block/fioa/queue/scheduler it was observed that neither the queue directory nor the scheduler file exist for that device. Is there way to view the IO Scheduler being used for the fioa device as well as change/tune it during runtime?
