Why `dasd_eckd` driver is overwritting the setting of `elevator` parameter in the system z?
Issue
- The I/O scheduler is set to be
noop
with the help ofelevator
parameter in /etc/zipl.conf - Still the scheduler is shown to be "deadline" in /sys/block/dasdcw/queue/scheduler.
Environment
- Red Hat Enterprise Linux 5.7
- Direct Access Storage Device(dasd)
- Device driver is dasd_eckd for dasd.
