The BVQ offline scanner collects information from IBM SVC or Storwize systems and puts it into a single zip file. The contained information consists of topology (configuration and runtime parameters), iostats (performance statistics), event- and audit-logs.

Topology and performance files include the names of volumes, mdisks, pools, hosts, etc. from the scanned system.

The zip file can be extracted for analysis purposes prior sending it to SVA. The transmission of the offline scanner zip file is encrypted by a https connection, when sending it via SVA Sharefile.


Data residing on a volume is not included in the collected data. Only the configuration and performance including the object names within is collected.

ZIP file content

The collected file types are .xml, .json, .properties, .log & .txt (the iostat files are the raw files coming from SVC/Storwize, but indeed these are XML files too with no filetype extension).
All Files can be opened with a Text editor (notepad(++), etc.) for checking the content.

svctask cpdumps

svctask cpdumps is used to copy iostat files from non-config nodes to the config node of the cluster. This command needs administrative rights to be executed, therefore the credentials used to connect to the cluster need to be in the Administrator group.

The gathered performance data (iostat) is copied via SCP (Secure Copy) from the cluster to the offline scanner. Other connections (topology, events, etc.) are established via SSH.
