Error Message
walk_dir: dirlist buffer

WARNING: cannot check for
cvc/ssp interface.
System Exploration Error Messages (Continued)
Probable Cause
As it walked the /dev and /
devices directories, the DR daemon
encountered too many directories,
causing a buffer overflow, . If this
message occurs, detection of or
protection against recursive symbolic
links is disabled.
The DR daemon cannot add another
directory to the target_path. The
daemon walks the /dev and
/devices directories to discover
device name links so that it can add
them to the target path. If the
daemon encounters this limit, it
cannot explore any more directories
because the buffer is full. If the
daemon stops it search, some of the
devices will not appear in the views
(DR daemon and SSP) of the domain
device tree. You may also see
improper autoswitching of AP
devices if this error occurs.
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 corresponds to the
SSP network interface for the
domain. The DR daemon will not
allow the detachability test to pass if
it cannot determine the SSP network
interface. If the network loses the
SSP network interface during a
detach operation, DR operations are
disabled in the domain, and
netcon(1M) sessions are disabled.
Suggested Action
Check the /dev and
/devices directories for
recursive symbolic links.
Remove any recursive symbolic
links that you find.
Devices that are not added to
the target path must be
manually unconfigured and
switched to other boards in the
domain. You may also need to
stop any daemon that is keeping
a device open.
Switch the suspected interface to
a redundant network connection
on another board. You may have
to reboot the domain to recover
from this error.
