Creating copy groups – HP XP Racks User Manual
Page 160
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.
