System Exploration Error Messages (Continued)
Probable Cause
The DR daemon could not open a
network device. All network devices
are opened to test their usage.
The /proc filesystem cannot be
opened. When the DR daemon
explores the domain to determine the
CPU information for a board, the
/proc filesystem is examined to
determine which PIDs, if any, are
bound to the CPUs on the board.
Bound processes negatively affect the
detachability of a board. A complete
detach operation will fail if processes
are bound to a CPU.
When the DR daemon tried to count
the amount of total memory, it could
report only the amount of memory
on the selected board, meaning that
the system memory field reported by
the drshow board_number mem
command is inaccurate. The
inaccuracy also negatively affects the
eligibility of a board for a Detach
operation because if the total
memory cannot be calculated, then
the effects of removing a board from
the domain cannot be calculated as
well.
Suggested Action
Determine what caused this
error by using 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.
Check to see why the
/proc filesystem cannot be
accessed. In the domain, process
binding and processor set
management programs, or
processor management
programs, can be used to
manually determine the CPU
information for a board.
Stop and restart the DR daemon
and driver. Report this error,
providing as much information
from the system logs as possible.
A memory leak could also have
occured over time. Check the
size of the DR daemon by using
the ps(1) command. The size
should be between 300- and 400-
Kbytes. If the size is not within
this range, stop and start the DR
daemon and driver.
