Abstract
The BVQ Offline Scanner scanner - for Storage, Compute or Network - is the application of choice to collect information for a BVQ analysis without installing any program. Start this application on any Windows, Linux or MacOS based server or laptop and let it collect configuration and performance information for a dedicated timeframe (hours up to days or weeks). This information is put into a single zip file which can be sent to a central BVQ service point (SVA or partners) where it will be analyzed for you. Transmission of the offline scanner zip file is encrypted by a https connection when sending it via SVA Sharefile.

There is one version of the tool available for each platform. To see which data is collected and how the data is collected, click on the desired platform:

User authentication and user roleProvide login credentials for an user in the Administrator user group. Administrative rights are required because the offline scanner uses the cpdumps-command to copy data from all nodes in the cluster to the config node. Performance statistics intervalPlease adjust the interval in which statistical performance data is collected:
This can be done using CLI command Note: If the systems are monitored by other products like IBM Spectrum Control oder IBM Storage Insights, then an interval < 5min cannot be set and the stats interval need to be changed in IBM Spectrum Control/IBM Storage Insights. Otherwise changes done on the CLI will be reset to whatever was configured on those tools. Time synchronizationBVQ server as well SVC/Storwize systems need to be synchronized with NTP.
Local filespace write access and free spaceThe data is collected in subdirectories and stored in the same filespace as the scanner binaries. Later in the process, this data will be packed into a zip file, typically stored into the directory 'My Documents'. The required capacity is mostly depending on the number of scanned volumes. Some estimated values:

Step 3.2: Define a profile
...
Offline Scanner scanner profiles allow to run more than one scanner in parallel. This is helpful in case multiple systems need to be scanned at the same time, e.g. two SVC systems in an remote copy partnership.
...
Fill in the information that is required to access the system which needs to be scanned:

If you scan a V7000 unified then please enter the IP address of the storage system, not the unified heads! The offline scanner can not distinguish between these systems and will not collect any data if the wrong IP address is entered. |
...
The tool cannot continue until all checks are successful!
Step 3.5: Scanning
...
In the next step, the offline scanner starts to collect data and copies the topology, eventlog and performance statistics in the according instance-directories.
Example: SVC Offline Scannerscanner
Note: If the tool is running for a longer timeframe, please check from time to time that the scanner is still running fine and still able to access the scanned system. The easiest way to do this, is to open the directory ./instances/<profilename> and check whether new data is coming in.
