How to: Using the Dr Northern Utility


The Dr Northern tool collects system information (system logs, etc.) and information about the NSS configuration (policies configured, trace files, etc.). This information is extremely useful in processing support cases and is almost always requested earlier in the case investigation process.

If you are using NSS 9.5 SR1 (9.50.17843.1402) or later Dr. Northern is part of the installation package. It is then located in the following path <Installation directory>\NORTHERN\Storage Suite\Tools\DoctorNorthernForNSS.

If you have an earlier version of NSS it is necessary to download the utility. Your case owner can provide you with a download link, upon request.
