0c7 This indicates a network dump is in progress, and the host is waiting
for the server to respond. The value in the three-digit display should
alternate between
0c7 and 0c2 or 0c9. If the value does not change,
then the dump did not complete due to an unexpected error.
0c8 This indicates you have not defined a primary or secondary dump
device. The system dump option is not available. Enter the
sysdumpdev
command to configure the dump device.
0c9 This indicates a dump started by the system did not complete. Wait
for one minute for the dump to complete and for the three-digit
display to change. If the three-digit display value changes, find the
new value on the list. If the value does not change, then the dump
did not complete due to an unexpected error.
8.1.2 Copying a System Dump
The following section discusses details of copying a system dump.
Figure 81. Copying a System Dump
After a crash, if the LED displays 0c0, then you know that a dump occurred and it
completed successfully. Press the reset button once. If there is enough space
to copy the dump from paging to the /var/adm/ras directory, then it will be
copied directly. If, however, at bootup the system determines that there is not
enough space to copy the dump to /var, the /sbin/rc.boot script (which is
executed at bootup) will call on the /lib/boot/srvboot script. This script in turn
calls on the
copydumpmenu
command, which is responsible for displaying the
following menu which can be used to copy the dump to removable media.
