DataDirect Networks SFA™ OS 1.5.3.0 Release Notes Revision B | 16
8.0 Support
To submit debug information to DDN, use the diag tgz command.
Diag is a captive account on SFA OS systems that is used for performing operations on a
controller when there’s no CLI access or the CLI isn’t appropriate. Perform diag
operations by using ssh to login to the diag account.
The command syntax is:
ssh [e-mail] diag-command
(where xxx.xxx.xxx.xxx is the controller’s IP address and diag-commands are listed in
Table 1.)
Table 1 Valid diag commands and descriptions
Command Description
help
Displays the help information.
clear
Clears all old crash files (it will clear a recursive crash).
reboot
Used to restart the controller if the RAID stack is not running. If the RAID
stack is running, this command will fail and you should use the CLI to
perform this operation.
shutdown
Used to shutdown the controller if RAID stack is not running. If the RAID
stack is running, this command will fail and you should use the CLI to
perform this operation.
tgz
Creates a .tgz file of all the crash information. The file is output to stdout
and since it’s a binary file, having it display on your terminal isn’t desirable.
Redirect stdout to your workstation with a command like:
ssh [e-mail] tgz > crash.tgz
