9 Using HP 3PAR Peer Motion Manager Software with
Recovery Manager
HP 3PAR Peer Motion Manager is a feature of the HP 3PAR Software and manages the migration
of data in between existing storage systems or third party storage arrays. HP 3PAR Recovery
Manager now supports HP 3PAR Peer Motion Manager data migration activities without any
impact on host operations while monitoring the primary storage system.
NOTE:
When using HP 3PAR Peer Motion Manager to move virtual volumes in between storage
systems, you must delete the data folder and subfolders from c:\program_files\3par\RM\sql
(default) folder and relaunch Recovery manager GUI.
For more information about performing Peer Motion data migration, refer to the HP 3PAR Peer
Motion User Guide. Go t
, navigate to your product page, click
Support for your product, and then click Manuals.
NOTE:
•
Peer motion only from StoreServ to StoreServ is supported.
•
Peer motion from EVA to StoreServ is not supported.
•
After Peer motion from StoreServ to StoreServ is completed, the HP 3PAR VSS Provider must
be modified to point to the new StoreServ and HP 3PAR VSS Provider service must be restarted.
NOTE:
If the device is presented using RDM (Raw Device Mapping) and if peer motion is
performed on that device, the device must ignore the SCSI INQUIRY Cache.
To configure the virtual machine with RDM to ignore the SCSI INQUIRY cache:
•
Add the following parameter to the .vmx file:
scsi x:y. ignoreDeviceInquiryCache = "true"
where x is the SCSI controller number and y is the SCSI target number of the RDM.
This parameter can be configured only on virtual machines with hardware version 8. Upgrade the
virtual machine to hardware version 8 before adding this parameter.
Enable this parameter only when it is recommended by the storage vendor. This parameter is
required for a limited number of storage arrays and only for specific guest operating systems. You
might need to reboot the system for the changes to take effect.
