NAME
acec reverse - Reverse the synchronous high-speed copying
SYNOPSIS
acec reverse -g copyGroup [-p copyPair] [-r] [-xml]
DESCRIPTION
This command reverses the direction of the synchronous high-speed copy for the specified copy group or copy pair.
When the Storage Cluster Continuous Copy function is used, the synchronous high-speed copy synchronization processing is reversed on both the Primary Storage and Secondary Storage.
OPTIONS
This option specifies the copy group name.
Only the following types of copy set in the copy group can be specified:
EC
REC
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 the synchronous high-speed copy synchronization processing is reversed 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 reverses the copying in the reverse direction to the direction that has been specified, so that the copy direction becomes the direction that has been specified.
This option specifies when displaying the result of the command execution by the XML format.
EXIT STATUS
=0: Completed successfully
>0: Terminated abnormally
EXAMPLES
When the Storage Cluster Continuous Copy function is not used
> acec reverse -g group01 ET001/0x1:ET001/0x6 # DATE : 2008/06/24 16:28:00 - << EC Change >> ET001/0x2:ET001/0x7 # DATE : 2008/06/24 16:28:00 - << EC Change >> ET001/0x3:ET001/0x8 # DATE : 2008/06/24 16:28:00 - << EC Change >> Succeeded : 3 Failed : 0
When the Storage Cluster Continuous Copy function is used
> acec reverse -g group01 ET001/0x1:ET001/0x6 # DATE : 2008/06/24 16:28:00 - << EC Change >> # Standby-Session : ET002/0x1:ET002/0x11 ET001/0x2:ET001/0x7 # DATE : 2008/06/24 16:28:00 - << EC Change >> # Standby-Session : ET002/0x2:ET002/0x12 Succeeded : 2 Failed : 0
NOTES
When the copy type of copy group is OPC, QuickOPC or SnapOPCP, this command cannot be executed.
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 reversed 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 reverses the synchronous high-speed copy synchronization processing for the storage device that has an "Active" TFO status and terminates normally.
