HP XP P9000 Replication Manager Software 7.5.0-02 Release Notes (TB584-96074, July 2013)

Adding command devices
When using the Add Command Devices Wizard, even though you cannot specify a pair volume as
a command device, the Candidate Devices screen might show primary volumes of Snapshot copy
pairs that are configured as V-VOLs without LUNs.
If you select such a volume and attempt to add a command device, an error occurs and the operation
does not complete.
Executing multiple tasks for the same copy pair
Some tasks may either remain in the Executing status in the GUI
1
or generate the RPM-00506,
KAVN00454-E, or KAVN00456-E error, depending on the types and combinations of the tasks.
Conditions
This behavior might occur when both of the following conditions are met:
1. Multiple tasks for the same copy pair are executed simultaneously.
2. The tasks include a task that changes the copy pair status.
2
Recovery procedure
For tasks that froze in the Executing status:
• Restart the XP P9000 Command View AE Suite Common Component service to reset the tasks to
the Failure status.
• Execute tasks again that you need to complete so that they are not executed simultaneously.
For tasks that generated an error:
• Execute tasks again that you need to complete after editing the failed tasks so that they are not
executed simultaneously.
1
Each task internally completes successfully or unsuccessfully, depending on the order of the execution.
2
Multiple tasks that set the copy pair status do not cause this behavior because one of the tasks reserves
the copy pair.
Pair relationships displayed for mainframe volumes in the Storage System view
The entry n/a might be displayed in the LDEV and Storage System columns of the Pair Relationship
display in the Storage System view if the following conditions are met.
Conditions
1. Business Continuity Manager is registered in Replication Manager as an information source.
2. The Business Continuity Manager in the first condition manages a volume of a storage system
that is managed by a local Device Manager.
3. In the Storage System view, you select a volume in a copy pair that is not managed by the Business
Continuity Manager in the first condition and then display pair relationships.
Removing and re-registering a Device Manager server as information source
Do not re-register a Device Manager server as information source for at least 24 hours after its removal
if there is a pair management server managed by the Device Manager server.
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.
