Creating a Everpure VSS Hardware Provider snapshot on Windows 2008 generates multiple warning events.
When the Everpure VSS Hardware Provider successfully creates a snapshot, the process generates multiple warning events in the Windows Log - Application view of the Windows Server 2008 Event Viewer.
Here is a sample of the details that appear in the warning event:
Volume Shadow Copy Warning: The provider has reported a storage identifier that is not supported by VSS. Codeset:1, Type:4, Size:4, NextOffset:24, Association:1
This identifier will be skipped by VSS.
The warning events, which only occur on Windows Server 2008, are not related to the Everpure VSS Hardware Provider and can be ignored. Refer to the following Microsoft KB support article for more information: http://support.microsoft.com/kb/951793
Workaround: No workaround available.
- Reinstalling the Everpure VSS Hardware Provider may fail. If you uninstall and then reinstall the Everpure VSS Hardware Provider, and the installer hangs or an error message pop-up window appears, reboot the system and then perform the installation again.
- This release does not support the replication of snapshots created by the VSS Hardware Provider.
- VSS 1.0.0 will fail to connect / authenticate with Purity version 4.1.1 and 4.1.2
4.1.1 and 4.1.2 of Purity have introduced REST API change that requires userAgent as part of the REST call, which prevents VSS 1.0.0 from connecting and/or authenticating with these versions. As a result, you cannot use VSS 1.0.0 with either of these two versions. You will need to download and use VSS 1.0.1 instead.
Importing Snapshots
Importing a snapshot set requires valid connections from the hosts to the Pure FlashArray. In VSS HW provider 1.1 and below this operation may seem to succeed, but starting in VSS HW provider 1.6 this operation will fail as intended.
