Refer to "6.5 Operations". However, "6.4 Preparations" are not required.
When using the Storage Cluster Continuous Copy function, note the following points:
Point
When the status of the TFO group is "Normal" and Advanced Copy cannot operate 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 storage device 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, swsrp2882 message may be output.
If a swsrp2882 message is output, after the status of TFO group has become "Normal" and the phase is not "Maintenance", refer to "7.10 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 "7.11.2 When Changing Storage Cluster Target Volume" and register the replication volume again.
For TFOVs that are not synchronized between the Primary Storage and Secondary Storage, the following commands cannot be executed:
swsrpstartsync command
swsrpmake command
swsrprevsync command
When the TFO status on the Secondary Storage is "Active", the following commands cannot be executed as well:
swsrpstat command
swsrpcancel command
To check the status of Advanced Copy and stop the session, use Web Console or AdvancedCopy Manager Copy Control Module commands.
For using Web Console
Refer to "Display/Forcible Suspend/Forcible Cancel Copy Session" in the Web Console Guide.
For using AdvancedCopy Manager Copy Control Module commands
accopy query command
accopy fcancel command
Refer to "Command References" in the AdvancedCopy Manager Operation Guide for Copy Control Module for information on the commands.
