Note: This registration process has risk because it is executed automatically
by /etc/horcmgr without judgment for protection mode in order to validate
the -fd option. This registration brings a degradation in horcmstart.sh, but
HORCM daemon has been running as usual, and it will depend on how many
devices a host has. To start faster at HORCM faster in non-protection mode,
create the $HORCMPERM file of "SIZE 0 byte" as a dummy file or to set
HORCMPERM=MGRNOINST. At this time, the -fd option shows Device_File
name as Unknown, and after you can use raidscan -find inst to validate
the -fd option.
