HP XP P9000 Replication Manager Software 7.6.1-00 User Guide

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.
• To specify the existing HORCM instances for which you do not want Replication Manager or
Device Manager to add or delete copy pairs or change copy pair statuses. You can view config-
uration information for copy groups and copy pairs included in the specified instance but cannot
perform any copy pair operations.
TIP:
HORCM instances created external to Replication Manager are not recognized and therefore not
provided in the list of candidate instances in the Create Group dialog box. You will need to perform
a configuration refresh for these instances to be recognized.

Creating copy groups
A copy group is created by assigning copy pairs to a pair group. For open systems pair configuration,
copy groups can be created on the 3. Group Management page of the Pair Configuration Wizard.
