Detach-Related Failure Error Messages (Continued)
Probable Cause
The ifconfig(1M) command failed to
unplumb the network interfaces. The
ifconfig(1M) command unplumbs
and brings down the network
interfaces before the board is detached.
One of the network interfaces on the
board could be busy, so manual
intervention may be needed.
The command failed. Certain daemons
keep network interfaces open
continuously. Those daemons must be
stopped before the devices they
control can be detached.
The kill(1) command failed. The
daemons that are used to control
certain network devices must be
stopped before the devices can be
detached because the daemons keep
the interfaces open continually.
The CANCEL ioctl() failed while
the DR daemon was trying to abort the
Detach operation. The failure caused
the board to be reported as being in
the UNREFERENCED state, indicating
that the memory has already been
drained.
Communication protocol has been
breached over the eligibility of a
board. To the SSP, the board is part of
the domain and has been, or is being,
drained of its resources. The SSP,
therefore, issues the abort command to
stop the Detach operation. However,
to the DR driver and daemon, the
board is not part of the domain.
Suggested Action
Log in to the domain, and, if
possible, unplumb the network
interfaces manually by using
the ifconfig(1M) command
with the unplumb option. The
manual execution of the
command may yield more
detailed information about the
failure.
Analyze the return_value to
determine why the kill(1)
command failed, and try to
correct the problem. If
necessary, use the ps(1)
command to obtain the PID
number for the daemons, and
use the kill(1) command to
stop the daemons manually.
Analyze the return_value to
determine why the kill
command failed, and try to
correct the problem. If

The board must be completely
detached before you can
recover from this error. Retry
the DR operation after the
board has been successfully
detached.
Exit and restart the DR
application.
