SFCFSHA installation: 12 nodes on RHEL 5 kernel 2.6.18

SF is configured initially and used to create fencing diskgroup, but after SFCFS is configured the vxsvc daemon won’t start.

The issue turned out to be a lack of semaphores available in the kernel.  This can be remedied by:

  1. update on-the-fly:
    echo 250 32000 32 1024 > /proc/sys/kernel/sem
  2. update permanently /etc/sysctl.conf by adding the following two lines to the end of the file:
    # Paul McKinley 20111208 set semaphores for SFCFSHA
    kernel.sem = 250 32000 32 1024
