NAME
acopc start - Start OPC or QuickOPC
SYNOPSIS
For OPC copy groups
acopc start -g copyGroup [-p copyPair] [-r] [-xml] acopc start -g copyGroup -concur [-xml]
For QuickOPC copy groups
acopc start -g copyGroup [-p copyPair] [-diff|-auto|-r] [-xml] acopc start -g copyGroup -concur [-diff|-auto] [-xml]
DESCRIPTION
This command performs OPC or QuickOPC for the specified copy group or copy pair.
When the Storage Cluster Continuous Copy function is used, OPC or QuickOPC is performed 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 copying 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 starts a differential copy.
If the -diff option is not specified, a full copy is started.
This option automatically selects full copy/differential copy of QuickOPC.
Depending on the statuses in the OPC Status and Copy Phase columns for the acopc query command, the following actions start:
OPC Status | Copy Phase | Processing Action |
|---|---|---|
OPC action not startup | Not set | Full copy starts. |
OPC Starting | N/A | After session stops, full copy starts. |
OPC Executing | Readying | After session stops, full copy starts. |
Copying | After session stops, full copy starts. | |
Tracking | Differential copy starts. | |
Copying/Tracking | Differential copy starts. | |
OPC Error Suspend | N/A | After session stops, full copy starts. |
When the Concurrent OPC function is in use, snapshots of multiple logical volumes are concurrently created, so the following actions start:
QuickOPC Session Status | Processing Action |
|---|---|
The statuses of Copy Phase in QuickOPC sessions are only "Tracking" and "Copying/Tracking". | Differential copy starts. |
Other than those above. |
|
This option performs a copy in the reverse direction to the direction that has been specified.
If the copy type is QuickOPC, an OPC is executed.
This option specifies when displaying the result of the command execution by the XML format.
This option executes OPC or QuickOPC by using Concurrent OPC function.
EXIT STATUS
=0: Completed successfully
>0: Terminated abnormally

NOTES
When the copy type of copy group is EC, REC 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 OPC or QuickOPC cannot be started 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 starts OPC or QuickOPC on the storage device that has an "Active" TFO status and terminates normally. However, OPC or QuickOPC 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 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.
