Known issues
This section details the known issues in version 4.4.0, along with best practices.
| Ticket ID | Description |
|---|---|
| VPSD-258648 | Supports only NTFS volume. |
| VPSD-258649 | When you create a Shadow Copy for dynamic disk on Microsoft Windows Server 2003, the Shadow Copy must be "transportable" type. |
| VPSD-258650 | Import operation for GPT + Dynamic disk is not supported on Microsoft Windows Server 2003. |
| VPSD-258651 | Incremental FlashCopy® does not support dynamic disks with concatenate volumes either spanned or striped, and does not support multi-target volumes for the same source disk. |
| VPSD-258652 | Drops support of DS6000, SAN Volume Controller 4.3.1 and earlier, and DS8000 CIM agent version 5.3 and earlier |
| VPSD-258653 | Supports only embedded CIM Agent. |
| VPSD-258654 | For DS8000® restore operation, space efficient volume or backgroundCopy of zero is not supported. |
| VPSD-258655 | For the SAN Volume Controller/Storwize V7000 cascading/multi-target FlashCopies with zero copy rate, after restoring one of the FlashCopy mappings, the current and newer FlashCopy relationships are withdrawn. The current target volume and newer FlashCopy volumes are returned to the free pool. |
| VPSD-258656 | For the SAN Volume Controller/Storwize V7000 cascading/multi-target FlashCopies with zero copy rate, after deleting one of the FlashCopy mappings, the current and earlier FlashCopy relationships are withdrawn. The current target volume and earlier FlashCopy volumes are returned to the free pool. The snapshot IDs of earlier FlashCopy volumes stay in host until the next snapshot/restore is run. Alternatively, ibmvcfg.exe cleanupDependentMaps can be used to clean up the snapshot IDs of earlier FlashCopy volumes manually. |
| VPSD-258657 | Before using the IBM® Virtual Disk Service, the prerequisite Java JRE 7.0 application must be installed. For example, ibm-java-jre-70-win-i386.exe or ibm-java-jre-70-win-x86_64.exe. |
| VPSD-258658 | IBM Virtual Disk Service provider is not automatically registered after installation. To manually register IBM Virtual Disk Service provider, issue the regsvr32 ibmvds.dll command under the directory of the IBM Volume Shadow Copy Service provider. |
Recommendations
- To use space efficient volume, it is recommended to set the backgroundCopy to zero.
- Mix volume types (fully allocated and space-efficient) of VDisks in VSS_FREE pool are not recommended.
- Mix copy rates in cascading/multi-target volumes are not recommended.
