Probable Cause
The information that is needed to
test each active network device could
not be acquired. While the network
devices are examined, each active
network device is tested to
determine if it is the primary
network interface for the domain.
The DR daemon will not allow the
detachability test to pass if it cannot
determine which active network
device is the primary network
interface for the domain.
The file that is needed to test each
active network device could not be
read. While the network devices are
examined, each active network
device is tested to determine if it is
the primary network interface for the
domain. The DR daemon will not
allow the detachability test to pass if
it cannot determine which active
network device is the primary
network interface for the domain.
The readlink(2) system call failed
when it encountered the devlink_file,
where devlink is the name of the
symbolic link in the
/dev directory.
Suggested Action
Analyze what caused this error
by using the open(2) man page
and the errno_value, and try to
correct it. Look for incorrect file
permissions or non-existent files.
The hostname_file value consists
of a file named /etc/
hostname.ifname, where ifname
is a device name, such as hme0
or le0.
Ensure that the file has the
correct permissions and that it
has not been corrupted.
Determine what caused this
error by using the readlink(2)
man page and the errno_value.
The DR daemon may have
encountered a resource limit. If
so, stop the daemon, then restart
it. Also, check the size of the DR
daemon. It should be between
300- and 400-Kbytes. If it is not
within this range, stop the
daemon, then restart it. If you
cannot recover the domain from
this error or if symptoms of a
memory leak exist, report this
error to your Sun service
representative, providing as
much information from the
system logs as possible.
