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).

About HORCM instances
A HORCM instance is the service (daemon process) that receives P9000 RAID Manager commands
and is started for each configuration definition. A HORCM instance is identified by the instance
number given to the configuration definition file name.
Replication Manager identifies available HORCM instance numbers and displays the smallest number
of available instance as the default HORCM instance when creating a new copy group. Depending
on availability of instances, the displayed instance number is updated automatically when you change
the primary or secondary pair management server.
The
server.agent.rm.exclusion.instance
parameter in the Device Manager agent
server.properties
file can be edited for the following purposes:

To specify the HORCM instance number that you want to exclude from Replication Manager or
Device Manager copy operations. Multiple HORCM instances can be specified for this parameter
by separating them with commas.
