When copying data by replicating VMware vSphere virtual machines or running Storage vMotion, Extended Copy (hereinafter referred to as "XCOPY") session starts by the Full Copy function of VMware vStorage APIs for Array Integration (VMware VAAI). However, Advanced Copy cannot be performed by AdvancedCopy Manager on the condition that a volume on which XCOPY session is running is taken as copy destination. For this reason, if you execute the acopc start or acec start command on the condition that a volume which is copying data by replicating virtual machines or running Storage vMotion is taken as copy destination, an error message is displayed and the command may terminate abnormally.
If the command terminates abnormally, check on Web Console or by the accopy query command that no XCOPY session exists on the copy destination volume and then re-execute the command.
