Command Logging
All changes that are made to RAID configurations using 3DM or CLI are
automatically stored in a special log file, tw_mgmt.log. This log can be
helpful to AMCC technical support for troubleshooting problems with your
RAID controller and units.
In Linux, FreeBSD and Mac OS X, tw_mgmt.log is in the /var/log directory.
In Windows, tw_mgmt.log is in the 3DM2 installation directory if 3DM2 is
installed on your system. If 3DM2 is not installed, the log file is in the home
directory of the current user.
When you install 3DM, you are given the option of turning Command logging
on or off. If you later want to disable it, you can do so through the CLI. (For
details see the
3ware Serial ATA RAID Controller CLI Guide
.)
There are other logs that may be useful to technical support. For instructions
in how to collect the system logs, see
