    Description

      Step 1: Install RHEL 6.2 using Platform HPC 3.1.
      Apart from the Platform HPC 3.1 extra packages, there are no custom changes to the RHEl 6.2 distribution nor updates at this point.

      Step 2: Packages installed.

      Step 3: Computer rebooted.

      Step 4: Run lctl set_param debug_mb=10
      [root@storage000 ~]# lctl set_param debug_mb=10
      debug_mb=10
      error: set_param: writing to file /proc/sys/lnet/debug_mb: Invalid argument
      [root@storage000 ~]#

      [root@storage000 ~]# cat /proc/sys/lnet/debug_mb
      121
      [root@storage000 ~]# echo 10 > /proc/sys/lnet/debug_mb
      -bash: echo: write error: Invalid argument
      [root@storage000 ~]#
