Starting with version 3.0 the upgrade from DB2 to version 10.5 FP2 is mandatory.
Please download first this DB2 version from the IBM website and then perform the upgrade. For instructions, please see the following document: DB2 upgrade from version 9.7.4 or higher to 10.5.
- Full support of SVC / Storwize version 7.3 including the new cache statistics
- Displays now the node port performance statistics of types: FC, IPREP, iSCSI, SAS and PCIe
- Multi screen support. Tabs can now be distributed in different windows on the desktop
- New start screen allows selection of multiple BVQ installations on one host
- Object type 'Disc type' now has an optional name and comment
SVC 7.3 cache metrics
Now the performance view additionally shows the new SVC 7.3 cache statistics. Only this allows a full analysis of the system's performance.
Particularly important advantages of the new 7.3 metrics are:
- Real IO sizes: all IOs are counted in real transaction sizes and not, as before, limited by 32KiB cache tracks.
- Upper / lower cache: they are displayed separated in upper cache and lower cache. All remaining 7.2 cache metrics are exclusively related to the upper cache.
- VDisk copy metrics: now statistics are available at the level of VDisk copy. Thus, the load which is caused by a VDisk competing with others of the pool (MDisk group) can be determined exactly.
Previously this was not possible especially in cases when VDisk mirroring, space efficiency, compression or flash copy were used. Please note: the object type VDisk inherently contains only the upper cache metrics.
The matching lower cache metrics can be found in the correlating VDisk copy of a VDisk.
End to end: the active chains in 7.3 can be represented as follows:
Reads VDisk SCSI layer → VDisk upper cache → VDisk copy lower cache → MDisk queue outbound → Node port Writes VDisk SCSI layer → VDisk upper cache partiton → VDisk copy lower cache partition → MDisk queue outbound → Node port
The new 7.3 metrics can be selected in a third tab in the options dialogue of the performance view. Here, for example, the metrics for object type 'Node':
It can be recognized that they are now differentiated in upper and lower cache .
Port statistics for SAS, PCIe, FCoE, iSCSI, IPREP
Now BVQ additionally displays the node ports of not-FC types like SAS, PCIe, FCoE, iSCSI and IP replication in the treemap and in the performance view.
This completes the analysis options in the port area.
Here is a look on the node ports of a first generation V7000 :
Here the appropriate options-dialogue of the performance view, which allows the access to appropriate metrics:
Some port types like FC & FCoE, SAS and IP replication have specific metrics which are visible at the bottom in the metric selection.
Multi window docking
Tabs can now be converted into window areas. These areas can be extracted from the main window and be placed on the desktop or they can also be ordered within a window next to or above each other .
Here, for example, two treemaps next to each other with transferred selection :
Or multiple performance views of different types with identical time axis within one analysis.
DB connection profile
BVQ DB connection profiles include the access data to BVQ databases. BVQ client tools (currently GUI and reporting) use these whe establishing a connection and enable their management. The profiles are stored in '.bdp' files centrally within the installation directory and can be exchanged throughout the company. All locally installed client tools are using the same .bdp files.
A BVQ GUI or BVQ Reporting GUI can thus be easily switched on all configured BVQ databases.
The following screenshot shows the GUI's selection dialogue:
Encrypted passwords are stored in the .bdp files.
Please note: license-fees have to be paid for each additional BVQ DB.
Disk type name and comment
The BVQ object type Disk type now has got an optional name and a comment field. With this subtle differences between two similar disc types can be expressed better (for example: '3.5' vs '2.5', or SAS vs SATA vs FC or even different transmission speeds).
The name is optional. If not specified, or an existing name is cleared, BVQ derives automatically a new one based on the configured attributes .
If the name is entered , for example, in BVQ CLI scripts it can later be used for the allocation of disk arrays. As a result, scripts can be created containing a complete image of a disk subsystem. The previously necessary query of the BVQ ID after creating the disc types is no longer needed. So this script can also be created offline ( for example from tables).

|IBM PMR 91765,033,724||SVC 184.108.40.206||Severe impairment of the VDisk latency by the SVC CLI command 'lsmdiskextent'. Seen at a cluster with 8 nodes (8G4) under 220.127.116.11. |
Starting with BVQ 2.4.3 this command is not used anymore. Instead command 'Isvdiskextent' is used.
Massive accumulation of reaching the SVC limit of 10 simultaneously competitive SSH sessions can trigger a warm restart of the node.
|BVQ-6610||BVQ VMware||Multiple mappings of a VM virtual disk (and/or of different snapshot versions of a single VM) to a VM virtual machine are not supported yet. |
This happens for example with flash copy managers like TSM4VE.

|IBM PMR ?||SVC Performance Stats|
Starting with version 18.104.22.168 SLAV, PLAV and DLAV refer to the consolidated backend IO sizes of up to 256k. But not the IO-counter for CTRM and CTP, which means that their quotient may be too low by a factor of 8. Therefore, the VDisk below cache metrics SLAV and PLAV cannot be used directly to assess the backend latencies. Also their transaction size is not the same of the backend (max 32k).
However, CTD was adapted to the consolidated IO sizes and provides continuously useful values.

- When configuring a topology scanner interval >30 min an adaptation in a GUI configuration file is necessary, concerning the scanner status checks. In this case please contact BVQ support.
- The Excel format generated by the BVQ Reporting is compatible with the Excel version of 2003 and higher. This is the format 'XML spreadsheet 2003' (please see this Microsoft article for more information).The standard file extension for this format is '.xml'. If it is despite saved with '.xls', a warning message appears when it is openend with Excel.
- License changes only take effect after about 2 hours or after restarting the scanner and scheduler.
- Currently not supported VMware functions:
- Partitioned VM SCSI volumes, whose partitions are assigned to multiple VM datastores.
- VM SCSI volumes whose UUIDs are not unique.
Summary: update steps
- * For an upgrade of BVQ Scanner from version 2.7 to 2.8 or higher should be noted that now a VMware Scanner can exist besides the SVC Scanner. Therefore, it is installed in a new default directory bvq-svc-scanner (previously bvq-scanner). To use the existing scanner configuration again, the update should be proceeded as follows before performing update step 3:
- Stop BVQ Scanner services manually
- Rename directory bvq-scanner in bvq-svc-scanner
- Continue with update step 3.
- Before possibly new functions can be used, a new license file is required.
After the import of the new license the GUI has to be restarted.
- The GUI is delivered with new predefined favorites. Only favorites from User favorites are retained.
We recommend to follow the sequence of update steps shown below.
- Checking for correct function of the environment, in particular function of the scanner.
- Manual stop of BVQ Scanner and Alerting-service, Scheduler-services and also of all GUIs and reporting-clients
- Backup of BVQ installation directory and BVQ DB (e.g. DB offline backup with DB2 CMD)
- Starting again the BVQ Scanner
- Update BVQ Install Package Repository:
- DB Schema update
- BVQ GUI update
- BVQ Reporting Engine update
- BVQ Report Module update
- BVQ SVC Scanner update
- BVQ VMware Scanner update
- BVQ Scheduler update
- BVQ Alerting update
- Performing functional tests
- If necessary inform colleagues about the need to update locally installed BVQ GUI / report clients.
