3PAR InForm Operating System 2.3.1 Release Notes (320-200178 Rev D, May 2010)

InForm OS Version 2.3.1 3PAR InForm Operating System Release Notes
2.8.3 Running Recovery Manager and Remote Copy (from outside of
Recovery Manager) at the Same Time is not Supported
To synchronize Recovery Manager snapshot data from the production site to secondary site,
Recovery Manager makes directly programmatic calls to the 3PAR Remote Copy product to
perform the background synchronization. When Recovery Manager is doing Applicant
Consistent Remote Syncs using Remote Copy in Asynchronous Periodic Mode, it is not required
to setup the periodic resync time for the Remote Copy groups. Setting up periodic resync time
for Remote Copy groups when recovery manager is active could disrupt the operation of
Recovery Manager.
 Workaround:
Remote Copy can support the mixture of Recovery Manager snapshots and Remote Copy
snapshots (outside of Recovery Manager) if the following procedure is followed:
Inside the Recovery Manager Windows scheduler script:
1) Set the Remote Copy period to 0.
2) Verify Remote Copy SyncStatus as "Synced".
3) Execute Recovery Manager snapshot creation for Remote Copy.
4) Wait for SyncStatus to be completed and Recovery Manager to take snapshot of
secondary volumes.
5) Recovery Manger will monitor the SyncStatus to be "Synced" every 120 seconds as
default then issue snapshot creation of secondary volumes.
6) Reset Remote Copy period to the sync period it was at prior to setting to 0 in step 1.
WARNING: Steps 2 and 4 are critical to ensure Recover Manager-created
snapshots and Remote Copy-created snapshots do not interfere with each other.
