IB Fabric: Manipulating HSM Autostart

# Stop all HSMs
cmdall "service qlogic_fm stop"

# Keep Them Off
cmdall "chkconfig qlogic_fm off"

# Turn an HSM on for a particular host. Keep it on for reboot.
# On the chkconfig command, the runlevels are specified in
# the init script itself. So, you don't have to specify
# "--level 235" for example.
cmdall -h st146 "service qlogic_fm start"
cmdall -h st146 "chkconfig qlogic_fm reset"
