HP 3PAR Online Import for EMC Storage Data Migration Guide

Preparing Host for Migration
To prepare for a successful migration, stop all applications on the host that may be accessing the
LUNs to be migrated. This also includes any replication and backup applications on the LUNs.
Next, set the LUNs to be migrated to an offline/unmounted state.
NOTE: Any applications and services that may automatically start with a reboot should be
disabled until after the migration has started and the documentation instructs you to bring your
host back online.
Preparing Windows Clusters for Migration
When migrating Windows clusters, the cluster must first be disabled so that any SCSI reservations
in use are released. For Windows 2008 R2 cluster, this can be achieved by stopping all applications
running on the cluster, then stopping the cluster service on ALL nodes (For more information, see
Microsoft's documentation on how to start/stop the cluster services).
When migrating a Windows Server 2012 cluster, maintenance mode must be set on the cluster
disks to clear SCSI reservations on the disks. Because the quorum disk cannot be set in the
maintenance mode, it must be set to the offline mode to clear the SCSI reservations. Then, the
cluster service must be stopped on ALL nodes.
Zoning the Host to the Destination HP 3PAR StoreServ Storage System
Zone the host to the destination HP 3PAR StoreServ Storage system to establish communication.
Validate Host to Destination connectivity using the 3PAR Management Tool by confirming host
initiator login on the 3PAR.
Shutdown the Host
Shutdown the host to continue offline migration.
Remove Host from the Storage Group
Using the EMC Unisphere tool, remove the host(s) from the storage group containing LUNs to be
migrated.
Identifying the Source and Destination Storage System
This section provides information on how to identify and add the source storage system for migration.
There are pre-requisites and information needed before beginning.
Pre-requisites
• The SMI-S Provider is installed and operational.
• HP 3PAR Online Import Utility is installed and operational with network access to both SMI-S
Provider server managing the source EMC Storage system and Management server for the
destination HP 3PAR StoreServ Storage system.
• Source EMC Storage system and destination HP 3PAR StoreServ Storage system are zoned.
