password. The FTDC Utility forces either or both controllers to restart if necessary
to collect the diagnostic information ftdc –ip 172.31.19.181 –allowoffline –log
mylog.
Development and Support Option
If you encounter a situation that makes it necessary to force the controller
firmware to restart and create the controller dump (CDUMP), you can enter the
parameter –forceoffline at the command line.
Note: Do not enter the –allowoffline parameter when using the -forceoffline
parameter. Example:
ftdc –ip 172.31.19.241 –forceoffline
CAUTION:
This option causes both controllers to reboot unconditionally and disrupts any
host I/O traffic . Users should only enter this option when directed to do so by
support personnel.
