When using an ETERNUS Disk storage system that supports the Offloaded Data Transfer (hereinafter referred to as "ODX") function, ODX session starts within the ETERNUS Disk storage system by Microsoft Windows Server Offloaded Data Transfer function when files are copied or transferred. However, Advanced Copy cannot be performed by AdvancedCopy Manager on the condition that a volume on which ODX session is running is taken as copy destination. For this reason, if the acopc start or acec start command is executed on the condition that a volume containing the area in which files are being copied or transferred by the Offloaded Data Transfer function 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 ODX session exists on the copy destination volume and then re-execute the command.
If the error is not resolved, review the copied volume or take either of the following actions to temporarily prevent the ODX session from running and then re-execute the command:
