NAME
acec start - Start the synchronous high-speed copying
SYNOPSIS
When the copy type set in the copy group is EC
acec start -g copyGroup [-p copyPair] [-r] [-da] [-xml]
When the copy type set in the copy group is REC
acec start -g copyGroup [-p copyPair] [-r] [-transfer {sync [-split {auto | manual}] | through | consist | stack}] [-recovery {auto | manual}] [-skip] [-da] [-xml]
DESCRIPTION
This command starts synchronous processing for the synchronous high-speed copy for the specified copy group or copy pair.
When the Storage Cluster Continuous Copy function is used, start the synchronous high-speed copy synchronization processing 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 systems copy pair that is the Storage Cluster pair is automatically retrieved from the specified pairs, and the synchronous high-speed copy synchronization processing is started 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 performs a copy in the reverse direction to the direction that has been specified.
This option specifies the transfer mode. (Only for REC)
The default mode is "stack". Refer to "3.2.2.5 REC Operating Modes" for information on each mode.
sync: Synchronous mode
This option specifies the split mode when sync was specified with the -transfer option (Only for REC)
-split
The default mode is "auto".
auto: Automatic Split
manual: Manual Split
through: Through mode
When the storage device is registered to operate by Copy command via LAN, this transfer mode cannot be specified.
consist: Consistency mode
stack: Stack mode
This option specifies the recovery mode. (Only for REC)
The default mode is "auto". Refer to "3.2.2.5 REC Operating Modes" for information on each mode.
auto: Automatic Recovery
manual: Manual Recovery
This option specifies when the synchronous process is suspended by using the initial copy skip function.
This option can be specified when the synchronous high-speed copy for inter-box is started.
From the start of the EC/REC synchronous high-speed copy process until its suspension, always set the copy destination logical volume to unreadable.
It is not possible to use this option if one registered the device as a device which is operated by Copy command via SAN and moreover has specified "through" with the -transfer option.
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.
This command terminates abnormally if the copy destination logical volume of the specified copy group or pair is protected by the acinhibit set command.
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 cannot be started on either or both of the Primary Storage or Secondary Storage, the command may be 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 state is "Normal" and its phase is "Maintenance", or when the status of the TFO group is "Halt", the command starts 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 started 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 TFO group state becomes "Normal" and the phase is not "Maintenance", refer to "3.12.11 When Recovering Storage Cluster Continuous Copy Function" to take action.
