4.7.1 acopc start (OPC/QuickOPC copy start command)

NAME

acopc start - Start of OPC or QuickOPC copy

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.

OPTIONS

-g copyGroup: This option specifies the copy group name.

-p copyPair: This option specifies a copy pair.

-diff

This option starts a differential copy.

If the -diff option is not specified, a full copy is started.

-auto

This option automatically selects full copy/differential copy of QuickOPC.

Depending on the statuses in the OPC Status and Copy Phase columns for acopc query (OPC/QuickOPC copy status display 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.	If no QuickOPC session exists: Full copy starts. If QuickOPC session exists: After session stops, full copy starts.

-r

This option performs a copy in the reverse direction to the direction that has been specified.

If the copy type is QuickOPC, an OPC will be executed.

-xml: This option specifies when displaying the result of the command execution by the XML format.

-concur: This option executes OPC or QuickOPC by using Concurrent OPC function.

EXIT STATUS

=0 : Completed successfully
>0 : Terminated abnormally
