The CTG option is available only when the prerequisite product versions are later than appropriate
version, so that Device Manager agent/P9000 RAID Manager can accept CTG option for local
copy.

Pairs created with the At-Time Split option (

-m grp

) and pairs created without this option must

not be mixed in the same group defined in the P9000 RAID Manager configuration file. If such
pairs are mixed, the pairsplit operation might end abnormally, or S-VOLs of the P-VOLs in the
same consistency group might not be created correctly at the time when the pairsplit request is
received.

Configuring open and mainframe consistency groups

The use of consistency groups across open and mainframe systems is supported for the Cnt Ac-S copy
type when using HP StorageWorks P9000 for Business Continuity Manager Software on
XP24000/XP20000 and HP P9500 storage systems.

When creating new pairs

1.

In the Pair Configuration Wizard (open system), specify the Assign CTG option in the Edit Task
dialog box (4. Task Management page) when creating the open Cnt Ac-S pairs.

2.

Open the

copy-group-name

subwindow (open systems) and confirm the CTGID assigned for

the open Cnt Ac-S pairs you created.

3.

Use the Pair Configuration Wizard (mainframe) to define the mainframe Cnt Ac-S pairs. On the
3. Group Management page, perform the following:

1.

Assign the same CTGID as the one you confirmed in step 2.

2.

Specify the Enable Open/MF CTG option in the Edit Group dialog box.

4.

Use HP StorageWorks P9000 for Business Continuity Manager Software to create pairs for the
pair definition configured in step 3.

When configuring existing pairs

1.

Confirm the mainframe and open Cnt Ac-S pairs share the same CTGID.

2.

Open the Pair Configuration Wizard for the mainframe pairs and specify the Enable Open/MF
CTG option in the Edit Group dialog box (3. Group Management page).

3.

Using the Change Pair Status Wizard, split the mainframe Cnt Ac-S pairs and then resync them
with the Assign CTG option enabled (3. Select Pair Operation page).
