NOT AVAILABLE
If the system restarts
in recovery mode,
the recovery applica-
tion will then use the
default configuration
data coded within
the recovery applica-
tion.
The e2prom recov-
ery configuration
data is removed and
if the system restarts
in recovery mode,
the recovery applica-
tion will then use the
default configuration
data coded within
the recovery applica-
tion.
AVAILABLE
The im.conf recovery
configuration data is
copied into the
e2prom. In this way,
if the system restarts
in recovery mode,
the recovery applica-
tion will then use the
same configuration
data reported by the
im.conf recovery
configuration data.
The im.conf recovery
configuration data is
copied into the
e2prom overriding
any previous configu-
ration present in the
e2prom. In this way,
if the system restarts
in recovery mode,
the recovery applica-
tion will then use the
same configuration
data reported by the
im.conf recovery
configuration data.
