HP P9000 Replication Manager Software 7.4.0-00 Release Notes (TB584-96062, December 2012)

Performing advanced operations per copy pair
When you have executed a takeover-recovery (recreate) operation to a copy group including copy
pairs in simplex status per copy pair, update the storage system information after the task is complete.
If you do not update the storage system information, you will be unable to perform any copy pair
operation to copy pairs in simplex status in the target copy group in Change Pair Status Wizard.
If you execute a takeover-recovery (resync) operation per copy pair, the task might generate the
KAVN02841-E (RPM-03351) error. If this error message appears, update the storage system
information. Even if the task generates this error, the operation on the copy pair or copy group completes
correctly.
Performing advanced operations
If you perform an advanced operation to a copy group while updating a storage system containing
a volume in the copy group using a Device Manager server or Refresh Configuration is being executed
for a remote Device Manager, the copy group might not appear in the Replication Manager GUI when
the operation is complete. If this happens, update the information of the storage system to which the
advanced operation was performed.
Performing task operations
Task operations might take a while when all of the following conditions are met:
1. The local Device Manager server manages a large number of hosts.
1
2. You select tasks and perform any of the following operations in Tasks view:
• Edit tasks
• Delete tasks
• Cancel tasks
1
The amount of time required depends on the number of hosts managed by Device Manager, the
number of tasks selected for the operation, and the performance of the Replication Manager server
machine.
If the number of hosts managed by Device Manager and the number of tasks selected for the operation
is around 20,000, it takes about several tens of seconds to several minutes.
Creating a 4x4 Continuous Access Journal copy group for a mainframe system
When creating a 4x4 Continuous Access Journal copy group for a mainframe system, in certain
configurations there are conditions for the specifiable EXCTG ID.
If you create a 4x4 Continuous Access Journal copy group for a mainframe system using Replication
Manager, Replication Manager does not check the specified EXCTG ID.
For details about the conditions for the specifiable EXCTG ID, see the HP XP P9000 for Business
Continuity Manager Release Notes.
Maintaining copy group consistency
For copy groups with consistency maintained between open systems and mainframe systems, you
cannot perform the following copy pair status change operations:
• Operations on the open system:
