This section explains the procedure for executing the Advanced Copy using the Storage Cluster Continuous Copy function.
Execution of Advanced Copy using the Storage Cluster Continuous Copy function is the same as that in the case of a non-TFOV. When specifying the copy pair using the -p option, specify either the Primary Storage or Secondary Storage copy pair.
Refer to "3.2 Executing Advanced Copy" for details about executing Advanced Copy.
Additionally, refer to "Chapter 4 Command References" for the specifications and case examples for each command.
Point
Volume protection cannot be configured for a TFOV.
When the TFO group status is "Normal", and Advanced Copy cannot be operated on either the Primary Storage or Secondary Storage, the command may terminate abnormally. Check the cause of the error on both the Primary Storage and Secondary Storage to address the error message in the ETERNUS Disk storage system where the error is occurring.
When the status of the TFO group is "Normal" and its phase is "Maintenance", or when the status of the TFO group is "Halt", the command executes Advanced Copy on the storage device that has an "Active" TFO status and terminates normally. However, Advanced Copy could not be executed on the storage device that has a "Standby" TFO status. In this case, ccm7002 message may be output.
If a ccm7002 message is output, after the status of TFO group has become "Normal" and the phase is not "Maintenance", refer to "3.12.11 When Recovering Storage Cluster Continuous Copy Function" to take action.
Advanced Copy cannot be operated during a failover or a failback.
If the volume that is the target of Storage Cluster or the TFO group of the volume is changed, refer to "3.12.12.2 When Changing Storage Cluster Target Volume" and register the copy pair again.
For TFOVs that are not synchronized between the Primary Storage and Secondary Storage, the following commands cannot be executed:
acopc start command
acec start command
acec suspend command
acec resume command
acec reverse command
