This issue did not affect the version of the Linux kernel as shipped with Red Hat Enterprise Linux 3, as it does not implement the sysfs file system ("/sys/"), through which dbg_lvl file is exposed by the megaraid_sas driver. Issue was addressed in Red Hat Enterprise Linux 4, 5 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2010-0076.html , https://rhn.redhat.com/errata/RHSA-2010-0046.html and https://rhn.redhat.com/errata/RHSA-2009-1635.html respectively.
