According to VCS SVCCopyService agent framework, a lock file should be created after the resource online. In the agent install and configuration guide, the lock file name is not mentioned exactly in any directory.
As the lock file is an internal agent specific file managed by VCS, it is not named precisely in VCS agent user guide.
The exact lock file name is an hidden flat file .VCS_SVCCopyServices_SVC_Copy_Online_Lockfile.DO-NOT-REMOVE under VCS agent directory /opt/VRTSvcs/bin/SVCCopyService.
