NAME
acec cancel - Stop the synchronous high-speed copying
SYNOPSIS
acec cancel -g copyGroup [-p copyPair] [-r] [-force] [-xml]
DESCRIPTION
This command stops the synchronous high-speed copy for the specified copy group or copy pair.
When the Storage Cluster Continuous Copy function is used, the synchronous high-speed synchronization processing is stopped on both the Primary Storage and Secondary Storage.
OPTIONS
This option specifies the copy group name.
This option specifies a copy pair.
When the Storage Cluster Continuous Copy function is used, specify either the Primary Storage or Secondary Storage copy pair. The ETERNUS Disk storage system copy pair that is the Storage Cluster pair is automatically retrieved from the specified copy pairs, and the synchronous high-speed copy synchronization processing is stopped on both the Primary Storage and Secondary Storage.
When specifying with the LU to Partition format or the Partition to LU format, you must enclose the entire argument for this option within double quotations (") depending on the shell being used.
This option stops copying in the reverse direction to the direction that has been specified.
This option forcibly stops the session.
This option specifies when displaying the result of the command execution by the XML format.
EXIT STATUS
=0: Completed successfully
>0: Terminated abnormally
EXAMPLES
When the Storage Cluster Continuous Copy function is not used
> acec cancel -g group01 ET001/0x1:ET001/0x6 # DATE : 2008/06/24 16:28:00 - << EC Disconnected >> ET001/0x2:ET001/0x7 # DATE : 2008/06/24 16:28:00 - << EC Disconnected >> ET001/0x3:ET001/0x8 # DATE : 2008/06/24 16:28:00 - << EC Disconnected >> Succeeded : 3 Failed : 0
When the Storage Cluster Continuous Copy function is used
> acec cancel -g group01 ET001/0x1:ET001/0x6 # DATE : 2008/06/24 16:28:00 - << EC Disconnected >> # Standby-Session : ET002/0x1:ET002/0x11 ET001/0x2:ET001/0x7 # DATE : 2008/06/24 16:28:00 - << EC Disconnected >> # Standby-Session : ET002/0x2:ET002/0x12 Succeeded : 2 Failed : 0
NOTES
When the copy type of copy group is OPC, QuickOPC or SnapOPCP, this command cannot be executed.
Specify the -force option to forcibly suspend REC session by executing this command if the REC transfer mode is Consistency mode or Stack mode. In this case, the consistency of the copy destination is not guaranteed.
Follow the procedure below to forcibly stop REC session.
Execute the acec suspend command with the -force option to forcibly suspend the REC session.
Execute the acec change command to change the REC transfer mode to Through mode.
Execute the acec resume command to restart the REC.
Execute the acec query command to check the copy phase is in an equivalency maintenance state.
Execute the acec suspend command to suspend the REC session.
Do not specify the -force option.
Execute this command to stop the REC session.
Do not specify the -force option.
When the Storage Cluster Continuous Copy function is used
When the status of the TFO group is "Normal", and synchronous high-speed copy synchronization processing cannot be stopped 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 stops synchronous high-speed copy synchronization processing on the storage device that has an "Active" TFO status and terminates normally, However, synchronous high-speed copy synchronization processing could not be stopped 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.
