Error description
In 810+ application protection fails with failed to unfreeze error due to 1. incorrect flush mechanism in \common\vm\winnt\TSMVmwareDpVSS\VSS\VSSLog.cpp in Flush() if m_bCanFlush is false - we DO flush and set it to true and after that we don't flush. But once we call DisableFlush() the next flush does write data. 2. new log entries and Flush() calls added in defect 125668 in \common\vm\winnt\TSMVmwareDpVSS\ProxyBAClient\CProxyBAClientModu le.cpp in CProxyBAClientModule::ActivateVSSFreeze() \common\vm\winnt\TSMVmwareDpVSS\ProxyBAServer\ProxyDispatcher.cp p in CProxyDispatcher::VSSFreeze() So as a result we do the following: 1. Call DisableFlush() which actually enebles it 2. Call freeze 3. Try to write logs to disk in Flush() when everything is frozen. -> reach 10 sec timout and fail. Products affected: IBM Spectrum Protect Backup-Archive Client version 7.1 on Windows Note: The Backup-Archive Client is a prerequisite to using the Data Protection for VMware. In Data Protection for VMware environments, the Backup-Archive Client is also known as the data mover. This problem also affects IBM Spectrum Protect for Virtual Environments: Data Protection for VMware 8.1.0. If you are using Data Protection for VMware 8.1.0, refer to APAR IT18396.
Local fix
Local Fix: - remove flush calls after freezing - fix Flush() - add EnableFlush()
