Starting with version 3.0 the upgrade from DB2 to version 10.5 FP2 is mandatory. From version 2.9 a new license file is recommended. Continued use of the old license file is also possible. In this case, new features will appear as 'Missing' in the license dialog and are thus deactivated. Otherwise the function of BVQ is not affected. |

Known problems
Issue ID | Module | Description |
|---|---|---|
| IBM PMR 91765,033,724 | SVC 6.2.0.3 | Severe impairment of the VDisk latency by the SVC CLI command 'lsmdiskextent'. Seen at a cluster with 8 nodes (8G4) under 6.1.0.4. Starting with BVQ 2.4.3 this command is not used anymore. Instead command 'Isvdiskextent' is used. |
| IBM PMR unknown | SVC 6.4.0.3 | 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. |
| BVQ-6623 | BVQ VMware | Scan and representation snapshots and thier capacities are not yet supported by BVQ. The 'Used Capacity' of a VM Virtual Disk corresponds currently to the 'Used Capacity' of the original VMDK file |
| IBM PMR ? | SVC performance stats | Starting with version 6.1.0.1 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. |
| IBM PMR ? | SVC 7.3 performance stats | Legacy VDisk cache statistics corrupted |
| IBM PMR ? | SVC 7.3 performance stats | Node CPU Core stats =0 |
| IBM defect 197194 | SVC 7.3 Performance Stats | CPT, OPT, APT much too high |
DB schema changes

Notes
- 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.
