Choosing a scheduler a boot time

["Costa, Jeff" <jcosta lendlease com>]

I cannot seem to select a different scheduler in RHAS4 from the default "cfq" scheduler. The scheduler choice appears to include any of these four schedulers: completely fair queuing, deadline, anticipatory, and no-optimal.

 

I'm assuming you simply append the correct scheduler name at the end of the "kernel" line in grub.conf so that it looks like this:

 

sched=cfg 

sched=dead

sched=as  

sched=noop

 

However, none of these seem to work. Any ideas?
