-all: This option specifies the displaying by the extended format.
Refer to the table of EXAMPLES for the displayed items.

-xml: This option specifies when displaying by the XML format.

EXIT STATUS

=0: Completed successfully

Operation Date	If an REC session exists, it displays the date for when the REC session state transitions indicated below last occurred (last execution date) in a "yyyy/mm/dd hh:mm:ss" format. The displaying of the date is performed on the basis of the target device's time zone. Starting of REC using the initial copy skip function (execution of acec start -skip) Suspend (execution of acec suspend) If a forced suspension was performed to an REC session in Hardware Suspend status, the last execution date will be initialized as "----/--/-- --:--:--." If a forced suspension was performed to an REC session while the execution of a copy was in progress, the last execution date will not be updated. Concurrent suspend (execution of acec suspend -concur) State transition to an error Suspend (EC Status column displays "EC Error Suspend"). State transition to a hardware Suspend (EC Status column displays "EC Hardware Suspend"). If any of the following conditions apply, the date will be displayed as "----/--/-- --:--:--." If an REC session does not exist (EC Status column displays "EC action not startup") If the initial copy (acec start) was started from a status of an REC session not existing If the REC session's copy status could not be acquired from the device (EC Status column displays "???") If using a device for which the last execution date recording function is not supported (ETERNUS DX60/DX60 S2/DX80/DX90, DX400 series, DX8000 series)

Table 4.16 When -progress, -da and -date Options Are Specified, or -all Option Is Specified
Title	Explanation
Copy Group Name	Displays the copy group name.
Copy Group Type	Displays the type of copy that has been set up for the copy group.
Disk Array Name	Displays the Box ID and ETERNUS name that was specified with the -a option for the acgroup create command.
Remote Disk Array Name	Displays the Box ID and ETERNUS name that was specified with the -remote option for the acgroup create command.
Source	Displays the logical volume for the copy source.
<=>	Displays the copy direction. N/A: No copying is performed. ==>: Copying from the source to the target. <==: Copying from the target to the source.
Target	Displays the logical volume for the copy destination.
SID(RSID)	Displays the Session ID of ETERNUS Disk storage system (i.e. the Disk Array Name) and the Session ID of remote ETERNUS Disk storage system (i.e. the Remote Disk Array Name).
EC Status	Displays the execution status of the REC. EC Starting: The REC is starting up. EC Executing: The REC is executing. EC Suspend: The REC is suspended EC action not startup: The specified session does not exist. EC Error Suspend: An error has occurred, preventing the copy process from continuing. EC Hardware Suspend: The REC has paused because of a hardware error, such as a problem with the path between hardware devices. 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. "EC Hardware Suspend(Use REC DISK)" and "EC Hardware Suspend(Use REC BUFFER)" are displayed in the following case. When the ETERNUS Disk storage system that was specified with the -a option for the acgroup create command is the copy source device of REC.
Copy Phase	Displays the current phase. Copying: Copy processing is executing. Paired: The copy is in the equivalency maintenance state. Not set: Either the specified session does not exist, or the copy process is not running.
Progress	Displays the progress of copy processes as a percentage. The "N/A" is displayed when the copy process is not executed. If the progress of copy processes is unknown, it is displayed "???".
Copied Block	Displays the number of blocks that have been copied.
Total Block	Displays the number of total blocks. If the number of total blocks is unknown, it is displayed "???".
Rcv	Displays the recovery mode for REC copies. auto: Indicates that the recovery mode is "Automatic". manual: Indicates that the recovery mode is "Manual". ----: Indicates that a REC copy is not being performed.
Split	Displays the split mode for REC copies. auto: Indicates that the split mode is "Automatic". manual: Indicates that the split mode is "Manual". ----: Indicates that either a REC copy is not being performed or that the mode is not synchronous mode.
Xfer	Displays the transfer mode for REC copies. sync: Indicates that the transfer mode is "Synchronous". through: Indicates that the transfer mode is "Through". consist: Indicates that the transfer mode is "Consistency". stack: Indicates that the transfer mode is "Stack". ----: REC copy is not being performed.
Copy DA	If the copy type is EC/REC, this displays the suppression settings for access to the copy destination area. on : Access is suppressed. off: Access is not suppressed. If the access suppression setting is unknown, it is displayed "???"
Operation Date	If an REC session exists, it displays the date for when the REC session state transitions indicated below last occurred (last execution date) in a "yyyy/mm/dd hh:mm:ss" format. The displaying of the date is performed on the basis of the target device's time zone. Starting of REC using the initial copy skip function (execution of acec start -skip) Suspend (execution of acec suspend) If a forced suspension was performed to an REC session in Hardware Suspend status, the last execution date will be initialized as "----/--/-- --:--:--." If a forced suspension was performed to an REC session while the execution of a copy was in progress, the last execution date will not be updated. Concurrent suspend (execution of acec suspend -concur) State transition to an error Suspend (EC Status column displays "EC Error Suspend"). State transition to a hardware Suspend (EC Status column displays "EC Hardware Suspend"). If any of the following conditions apply, the date will be displayed as "----/--/-- --:--:--." If an REC session does not exist (EC Status column displays "EC action not startup") If the initial copy (acec start) was started from a status of an REC session not existing If the REC session's copy status could not be acquired from the device (EC Status column displays "???") If using a device for which the last execution date recording function is not supported (ETERNUS DX60/DX60 S2/DX80/DX90, DX400 series, DX8000 series)

NOTES

When the copy type of copy group is OPC, QuickOPC or SnapOPCP, this command cannot be executed.
Information such as Copy direction data and SID data may display as "???". Refer to "5.3 Resolving for Displaying "???" in Advanced Copy Status" and take action.
