Configuration utilities
ccmd
If started with no options,
ccmd
disassociates itself from the terminal or
window where it was started. It instead reports to the console window
and the file /spp/data/ccmd_log.
If
ccmd
is sent a
SIGHUP
, it regenerates the database.
All scan-based operations require
ccmd
. If POST is unable to run, then
ccmd
is not able to read configuration data and some system information
is not accessible.
ccmd
works in co-operation with most utilities to share a common
ethernet port and Diagnostic (DART) bus. In general, the scan data is
sent via UDP. The DART bus should be separate from any general
purpose ethernet bus. If the DART bus is improperly set-up,
ccmd
cannot
run properly.
Since
ccmd
can become corrupted by bad data, it may be necessary to kill
the
ccmd
process to refresh the SSPs configuration image. Killing the
ccmd
process is not always enough. If the “heart beat” LED from the
SCUB is not functioning then
ccmd
is unable to communicate with the
system. A
ping
command to the SCUB will not be successful either. In
this case, the system or node must be powered down to reset the SCUB
and re-establish communication with the SSP.
