You can really screw up if the interfaces are in (permanently) disabled
state and the machine reboots, intentionally or because of a crash. The
clustering will not work, the FP interfaces will not come up and you are
left without any means of accessing the machine except going around
searching for the right console cable.=20

Tim,

I believe the state should be persistent, too. One bug related to this
issue is TED00018877 (The second SSC interface sc2 is showing Operation
column "up" with out connecting cable.)

Subject: sc interface state

The 'interface modify <name> -s enable' and 'interface modify <name> -s
disable'
commands are currently used to enable/disable sc and fp network
interfaces.
However, the state of the sc interfaces is not currently persistent. If
you disable an sc interface and
then reboot, the interface will be always be configured up if there is
an IP address configured.

Is this the desired behavior or is this a defect?

I believe that the state should be persistent as it is for the fp
interfaces.
Unless I hear otherwise, I am going to change this as part of another sc
interface defect I am working on.

Tim
