NAME
acsnap cancel - Stop of SnapOPC+ copy
SYNOPSIS
acsnap cancel -g copyGroup [-p copyPair | -v volumeName] [-r | -force][-xml] acsnap cancel -estimate -v volumeName [-xml]
DESCRIPTION
The SnapOPC+ copy for a specified copy group or pair is cancelled.
If the -estimate option is specified, the monitor session of the update amount measurement is stopped.
OPTIONS
This option specifies the copy group name.
This option specifies a copy pair.
When specifying the copy pair of the past snap generation (except the oldest snap generation), execute this command with the -force option.
When the acsnap start command was executed by specifying both the -r and -p options, it is necessary to specify this option to cancel the SnapOPC+ copy.
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 stops copying in the reverse direction to the direction that has been specified.
This option forcibly stops the session.
Cancelling SnapOPC+ process forcibly stops all the snap generations of a pair specified to stop and earlier snap operations.
If no pair is specified, SnapOPC+ process is forcibly cancelled for the latest snap generation, so that all snap generations are stopped.
This option is specifiable even if there is only one snap generation.
The copy process of a specified logical volume is cancelled.
If the -force option is not specified, the copy process of the oldest snap generation is cancelled.
If the -force option is specified, the copy process of the latest snap generation is cancelled.
If the -r option is specified, the restore process of the latest snap generation is cancelled.
When stopping the monitor session of the update amount measurement, specify a logical volume to be measured.
The following is an example of a format to specify a logical volume.
(1) ETERNUS name
(2) Logical volume number
The extent start position and the extent size can be specified.
(1) ETERNUS name
(2) Logical volume number
(3) Extent start position (block units)
(4) Extent size (number of blocks)
A character string starting with "0x" expresses a hexadecimal value.
When specifying the extent start position and the extent size, you must enclose the entire argument for this option within double quotations (") depending on the shell being used.
Specify this option when stopping the monitor session of the update amount measurement.
This option specifies when displaying the result of the command execution by the XML format.
EXIT STATUS
=0: Completed successfully
>0: Terminated abnormally
EXAMPLES
Stopping the SnapOPC+ copy
> acsnap cancel -g group01 ET001/0x1:ET001/0x6 # DATE : 2008/06/24 16:28:00 - << SnapOPCP Disconnected >> ET001/0x2:ET001/0x7 # DATE : 2008/06/24 16:28:00 - << SnapOPCP Disconnected >> ET001/0x3:ET001/0x8 # DATE : 2008/06/24 16:28:00 - << SnapOPCP Disconnected >> Succeeded : 3 Failed : 0
Stopping the monitor session of the update amount measurement
> acsnap cancel -estimate -v ET001/0x1 Successful completion.
NOTES
If you stop a session of defined Concurrent OPC (Readying), specify a copy pair by using the -p option.
When the copy type of copy group is OPC, QuickOPC, EC or REC, this command cannot be executed.
This command is not available for ETERNUS Disk storage system registered as a remote device.
