/RESTART-CLONE-SESSION
When the command is executed, the data is copied from the original unit to the clone unit. No other access may take place to either of these units.
The original units of the clone pairs are specified in the UNIT operand.
When the original units are selected via a pubset (UNIT=*BY-PUBSET), clone units must exist for all units of the pubset. The clone pubset on the clone units can be renamed for ETERNUS DX/AF with QuickOPC directly using the NEW-PUBSET operand if an SF pubset is involved.
For the restart the clone units can be selected explicitly (e.g. by means of the catalog ID of a renamed pubset) or implicitly according to their position in a SYSOUT output (*FROM-SHOW-OUTPUT(...) operand).
SHC-OSD checks the global and task-specific security settings before this command is executed (see "Security settings of SHC-OSD"). The current security settings can be displayed with /SHOW-SHC-PROCESSING (see also "SHOW-SHC-PROCESSING Displays settings of SHC-OSD"). They can be changed in the SHC-OSD parameter file (see "Configuration of SHC-OSD") for the next time SHC-OSD is started or with /MODIFY-SHC-PROCESSING for ongoing operations (see "MODIFY-SHC-PROCESSING Changes settings of SHC-OSD").
For QuickOPC
The command is executed only if the clone pair has the SPLIT status. After the restart, the status of the clone pair changes from SYNCHRONIZING to SPLIT. The clone unit can be accessed by the host directly after this command has been executed. The data of the clone unit are updated in the background.
When the REC function is used, the original unit can also be the source unit of a remote copy pair. The target unit can also be the original unit of a clone pair. In this case the source unit is specified in the UNIT operand, and the clone pair of the target unit is selected using the SELECT=*TARGET-UNIT operand.
For EC
The command is executed only if the clone pair has the SPLIT status. After the restart, the status of the clone pair changes from SYNCHRONIZING to SYNCHRONIZED.
When the REC function is used, the original unit can also be the source unit of a remote copy pair. The target unit can also be the original unit of a clone pair. In this case the source unit is specified in the UNIT operand, and the clone pair of the target unit is selected using the SELECT=*TARGET-UNIT operand.

UNIT =
Selects the units by means of a particular VSN (*BY-VOLUME), a particular catalog ID (*BY-PUBSET), by means of the serial number and the internal number of the logical volume in the storage system (*BY-STORAGE), or directly by means of the logical volume's mnemonic device name.
UNIT = *BY-VOLUME(...)
Selects the units by means of a particular VSN.
VOLUME = <vsn 1..6>
Specifies the volume’s VSN.
UNIT = *BY-PUBSET(...)
Selects units by means of a pubset ID or volume set ID. The pubset is protected against reconfiguration during command processing.
PUBSET = <cat-id 1..4>
Specifies the pubset ID or volume set ID.
NEW-PUBSET =
Only relevant with QuickOPC.
Determines the catalog ID of the clone pubsets of the clone units.
NEW-PUBSET = *SAME
The clone pubset is not renamed, i.e. it retains the same name.
NEW-PUBSET = *SPECIAL-VSN
All volumes of the clone units are automatically renamed to prevent confusion with the original. For this purpose the period in a VSN in point notation is changed to a colon (e.g. AA.001 to AA:001), or in PUB notation the PUB string is changed to P:B (e.g. PUBA01 to P:BA01).
NEW-PUBSET = <cat-id 1..4>
An SF pubset’s clone pubset is renamed by specifying the new catalog ID explicitly. The catalog ID can also differ in length from the PUBSET operand. The new clone pubset also becomes an SF pubset. An existing MRSCAT entry is used if it is of the correct type. If it is not, it is deleted and created again. See the notes in section "Renaming SF pubsets with SHC-OSD".
HOLD-IO =
Only relevant for QuickOPC.
Handles inputs/outputs on the clone pair during splitting (see “Consistent splitting of a pubset in the shared pubset network” in "Synchronization point for replications").
HOLD-IO = *NO
The inputs/outputs on the original units are executed without any change. This can lead to data inconsistencies on the clone units for applications which are not suspended before splitting takes place.
HOLD-IO = *UNTIL-ACTIVATED
The inputs/outputs on the original units are suspended until all the imported pubset’s clone pairs are in the COPY-ON-WRITE status. Subsequently inputs/outputs to the units are resumed. If an error occurs when inputs/outputs are suspended or resumed, the command is aborted. The input/output activity may need to be resumed using /RESUME-IO.
UNIT = *BY-STORAGE(...)
Selects the unit by means of the serial number and the internal number of the logical volume in the storage system.
SERIAL-NUMBER = <alphanum-name 3..14>
Specifies the serial number of the storage system (make sure it is unique!).
LOGICAL-VOLUME = <x-text 1..4>
Specifies the internal number of the logical volume in the storage system.
UNIT = list-poss(256): <alphanum-name 2..2> / <x-text 4..4>
Selects the unit by means of the mnemonic device name of the logical volume.
CLONE-UNIT =
Selects the clone unit. If more than one clone unit exists for a unit, a specific clone unit must be selected.
CLONE-UNIT = *FIRST-POSSIBLE
Selects the first possible clone unit for the command.
CLONE-UNIT = *FROM-SHOW-OUTPUT(...)
Selects the clone unit via its position in the output list of /SHOW-CLONE-SESSION-STATUS.
POSITION = <integer 1..16>
Specifies the position of the clone unit.
POSITION = *LAST
Selects the last clone unit in the output list.
CLONE-UNIT = *BY-PUBSET(...)
Selects the clone unit via the pubset ID of the activated and renamed pubset.
CLONE-PUBSET = <cat-id 1..4>
Specifies the pubset ID.
CLONE-UNIT = *BY-STORAGE(...)
Selects the unit by means of the internal number of the logical volume in the storage system.
CLONE-LOGICAL-VOLUME = <x-text 1..4>
Specifies the internal number of the logical volume in the storage system.
CLONE-UNIT = list-poss(256): <alphanum-name 2..2> / <x-text 4..4>
Specifies the mnemonic device name of the logical volume.
CLONE-TYPE=
Specifies the clone type (and thus also the replication function) that is used.
CLONE-TYPE = *UNIQUE
Selects the clone type that is determined clearly by the explicit selection at CLONE-UNIT.
CLONE-TYPE = *COPY
The COPY clone type (and thus the QuickOPC replication function) is selected.
CLONE-TYPE = *MIRROR
The MIRROR clone type (and thus the replication function EC) is selected.
SELECT =
Selects the clone pairs.
SELECT = *STD
Selects the clone pairs which were defined using the UNIT operand.
SELECT = *TARGET-UNIT
Selects the clone pairs which are assigned to the target unit of a remote copy pair. The relevant source unit is specified in the UNIT operand.
The selection can only be made if the target unit is unique. Concurrent remote copy is not supported here.
WAIT =
Specifies whether the command is to wait until synchronization is complete.
WAIT = *NO
The command does not wait until synchronization is complete.
WAIT = *UNTIL-SYNCHRONIZATION
The command waits until synchronization is complete.
WAIT=*UNTIL-SYNCHRONIZATION simplifies the programming of test procedures because extensive queries regarding the synchronization progress are unnecessary.
Command processing
The following messages are output to SYSOUT for each director and distributed via routing code 0, i.e. they are logged in the CONSLOG file only. You will find detailed information on the CONSLOG file (log file) in the “Introduction to System Administration” manual [5].
