The shconf command is invoked when SHD is enabled. It manages the system
hang detection parameters.
The shconf command syntax is as follows:
shconf [ -D | -E ] [ -O ] -l Name
shconf -l Name -a Attribute=Value ...
5.3 System dump status check
5.3.1 Status codes
When a system dump is taking place, status and completion codes are displayed
in the operator panel display. When the dump is complete, a 0cx status code
displays if the dump was user initiated, and a flashing 888 displays if the dump
was system initiated.
You can check whether the dump was successful, and if not, what caused the
dump to fail, if a 0cx code is displayed.
Note: If the dump fails, upon reboot, look for an error log entry with the label
DSI_PROC or ISI_PROC. If the Detailed Data area shows an EXVAL of 000
0005, this is probably a paging space I/O error. If the paging space is the
dump device or on the same hard drive as the dump device, the dump may
have failed due to a problem with the hard drive. Diagnostics should be run
against that disk.
The following are the list of status codes for the system dump:
000 The kernel debugger is started. If there is an ASCII terminal attached to
one of the native serial ports, enter q dump at the debugger prompt (>) on
that terminal and then wait for the flashing 888s to appear in the operator
panel display. After the flashing 888 appears, go to 5.6, “Copying a
system dump” on page 77, which describes how to check the dump
status.
0c0 The dump completed successfully. Go to 5.6, “Copying a system dump”
on page 77.
0c1 An I/O error occurred during the dump.
0c2 A user-requested dump is not finished. Wait at least one minute for the
dump to complete and for the operator panel display value to change. If
the operator panel display value changes, find the new value on this list.
If the value does not change, then the dump did not complete due to an
