SYNOPSIS
acpair add -g COPY-GROUP -p PAIR [-xml]
DESCRIPTION
This command adds copy pairs to copy groups.
OPTIONS
This option specifies the copy group name.
This option specifies the copy pair to be added.
The following example shows the format for specifying copy pairs.
(1) ETERNUS name for the copy source
(2) Logical volume number for the copy source
(3) ETERNUS name for the copy destination
(4) Logical volume number for the copy destination
This option can also be specified in LU to Partition format.
An example is shown below.
(1) ETERNUS name for the copy source
(2) Logical volume number for the copy source
(3) Extent start position for the copy source volume (block units)
(4) Extent size for the copy source volume (number of blocks)
(5) ETERNUS name for the copy destination
(6) Logical volume number for the copy destination
(7) Extent start position for the copy destination volume (block units)
Character strings starting with "0x" are hexadecimal expressions.
This option specifies when displaying the result of the command execution by the XML format.
EXIT STATUS
=0 : Completed successfully
>0 : Terminated abnormally
EXAMPLES
Adding a copy pair in LU to LU format
> acpair add -g group01 -p ET001/0x1:ET001/0x6 Successful completion.
Adding a copy pair in LU to Partition format
> acpair add -g group01 -p ET001/0x122[addr=0x0,size=0x1]:ET001/0x121[addr=0x0] Successful completion.
NOTES
Make sure that the logical volumes specified for the copy source and the copy destination are of the same size.
If the copy type is OPC, QuickOPC or EC
Specify the ETERNUS name that was specified with -a option for acgroup create (Copy group creation command).
If the copy type is SnapOPCP
Specify the ETERNUS name that was specified with -a option for acgroup create (Copy group creation command).
In the case that the copy source of the specified copy pair is same with other copy pairs, an error will occur when the number of SnapOPC+ max session is exceeded.
An error will occur when the copy destination of the specified copy pair is not SDV.
If the copy type is REC
Specify the ETERNUS name that was specified with either -a or -remote option for acgroup create (Copy group creation command).
Specify different ETERNUS names for the copy source and the copy destination.
The copy source ETERNUS name and the copy destination ETERNUS name for the copy pair being added must be the same as the copy source ETERNUS name and copy destination ETERNUS name for any copy pairs that have already been added to the copy group.
