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.
