Is there a way to turn on verbose logging for NDMP on the Celerra?

Make sure you replace "server_x" with the actual Data Mover you are working on (ex. server_2).

Use the same syntax, but use LOG_DBG2 instead of LOG_ERR.  LOG_ERR is the default logging level, so you won't get anything new with that.  There is a LOG_DBG3, but it prints way too much information that is not useful.  Just know that there is another level of logging in case your backup vendor says he wants more.

This information will dump to the server log.  Use the server_log command to retrieve it.  Example using server_2:

server_log server_2 -a -s > slog2.txt

Also, we would ask that you please reset the logging level back to LOG_ERR when you are done.  If not, you could end up filling the log with NDMP debug information and you could potentially overwrite something important.  Just use your original posted syntax to do that:

.server_config  server_x  "logsys set severity NDMP=LOG_ERR"

.server_config  server_x  "logsys set severity PAX=LOG_ERR"

Finally, please note that this logging setting is not persistent across reboots. 

And one more note for legality:

The commands we are discussing are UNSUPPORTED and UNDOCUMENTED.  Use them at your own peril.  While we have never know this command to cause problems, the potential is there.  Also, usupported and undocumented commands could cause unexpected results or even cease working at any time without notice.  This forum posting DOES NOT constitute "documentation" of this command.
