4.7.3 acec suspend (Synchronous High-speed Copy Temporary Suspension Command)

NAME

acec suspend - Suspension of synchronous high-speed copying

SYNOPSIS

For EC copy groups

acec suspend -g copyGroup [-p copyPair | -concur] [-r] [-xml]

For REC copy groups

acec suspend -g copyGroup [-p copyPair] [-r] [-force] [-xml]
acec suspend -g copyGroup -concur [-r] [-xml]

DESCRIPTION

This command temporarily suspends the synchronous high-speed copy for the specified copy group or copy pair.

OPTIONS

-g copyGroup: This option specifies the copy group.

-p copyPair: This option specifies a copy pair.

-concur

This option suspends synchronous high-speed copy using the concurrent suspend function.

When the copy type of the copy group is REC, this option can be specified only if the transfer mode is not Stack mode.

-r: This option temporarily suspends copying in the direction opposite to the specified one.

-force

This option forcibly and temporarily suspends the REC session.

If the execution status (EC Status) displayed with the acec query command is either of the following, it is impossible to forcibly suspend the REC session.

EC Hardware Suspend(Use REC DISK) : The REC Disk buffer is in use because of a hardware error, such as a problem with the path between hardware devices.
EC Hardware Suspend(Use REC BUFFER) : The REC transfer buffer is in use because of a hardware error, such as a problem with the path between hardware devices.

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

EXIT STATUS

=0: Completed successfully
>0: Terminated abnormally

EXAMPLES

Suspending synchronous high-speed copy (no using the concurrent suspend function)

> acec suspend -g group01

ET001/0x1:ET001/0x6
# DATE : 2008/06/24 16:28:00 - << EC Suspended >>

ET001/0x2:ET001/0x7 
# DATE : 2008/06/24 16:28:00 - << EC Suspended >>

ET001/0x3:ET001/0x8
# DATE : 2008/06/24 16:28:00 - << EC Suspended >>

  Failed    : 0

NOTES

When the copy type of copy group is OPC, QuickOPC or SnapOPCP, this command cannot be executed.

One of the following messages may be displayed when this command is executed by specifying the -concur option for the REC copy group.

ccm5004 Operation failed. function=stxcec.SUSPEND.concur, message=STXC1002 ERROR Invalid logical volume name. Volume name=(0xa@00ETERNUSDXH##ET87S20A####NC4110699004##).

ccm5004 Operation failed. function=stxcec.SUSPEND.concur, message=STXC1034 ERROR The set Alias name for the option to specify the target to which the copy request is issued is not the copy source or is not the copy target.

ccm5004 Operation failed. function=stxcec.SUSPEND.concur, message=STXC1035 ERROR The set Alias name for the option to specify the target to which the copy request is issued exists, but access path information does not exist.

Check that ETERNUS Disk storage system of the copy source is not registered as a remote device, if the above message is displayed.

If the problem is not resolved, follow the procedure in "Changing Information Other than ETERNUS Names and Access Volumes" and execute this command after re-registering the copy source ETERNUS Disk storage system.
