NAME
acec suspend - Suspend the synchronous high-speed copying
SYNOPSIS
For EC copy groups
acec suspend -g copyGroup [-p copyPair | -concur] [-r] [-xml]
For REC copy groups
acec suspend -g copyGroup [-p copyPair] [-r] [-force] [-xml] acec suspend -g copyGroup -concur [-r] [-xml]
DESCRIPTION
This command temporarily suspends 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 copy synchronization processing on both the Primary Storage and Secondary Storage is temporarily suspended.
OPTIONS
This option specifies the copy group.
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 pairs, and the synchronous high-speed copy synchronization processing on both the Primary Storage and Secondary Storage is temporarily suspended.
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 suspends synchronous high-speed copy using the concurrent suspend function.
When the copy type of the copy group is REC, this option can be specified only if the transfer mode is not Stack mode.
This option temporarily suspends copying in the direction opposite to the specified one.
This option forcibly and temporarily suspends the REC session.
If the execution status (EC Status) displayed with the acec query command is either of the following, it is not possible to forcibly suspend the REC session.
EC Hardware Suspend(Use REC DISK) : The REC Disk buffer is in use because of a hardware error, such as a problem with the path between hardware devices.
EC Hardware Suspend(Use REC BUFFER) : The REC transfer buffer is in use because of a hardware error, such as a problem with the path between hardware devices.
This option specifies when displaying the result of the command execution by the XML format.
EXIT STATUS
=0: Completed successfully
>0: Terminated abnormally

NOTES
When the copy type of copy group is OPC, QuickOPC or SnapOPCP, this command cannot be executed.
One of the following messages may be displayed when this command is executed by specifying the -concur option for the REC copy group.
ccm5004 Operation failed. function=stxcec.SUSPEND.concur, message=STXC1002 ERROR Invalid logical volume name. Volume name=(0xa@00ETERNUSDXH##ET87S20A####NC4110699004##).
ccm5004 Operation failed. function=stxcec.SUSPEND.concur, message=STXC1034 ERROR The set Alias name for the option to specify the target to which the copy request is issued is not the copy source or is not the copy target.
ccm5004 Operation failed. function=stxcec.SUSPEND.concur, message=STXC1035 ERROR The set Alias name for the option to specify the target to which the copy request is issued exists, but access path information does not exist.
Check that ETERNUS Disk storage system of the copy source is not registered as a remote device, if the above message is displayed.
If the problem is not resolved, follow the procedure in "Changing Information Other than ETERNUS Names and Access Volumes" and execute this command after re-registering the copy source ETERNUS Disk storage system.
When the Storage Cluster Continuous Copy function is used
When the status of the TFO group is "Normal", and the synchronous high-speed copy synchronization processing on either the Primary Storage or Secondary Storage cannot be temporarily suspended, 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 temporarily suspends the synchronous high-speed copy synchronization processing on the storage device that has an "Active" TFO status and terminates normally. However, the synchronous high-speed copy synchronization processing could not be temporarily suspended 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.
