6 Performing MDM Using a Windows Host
The MDM process is used when migrating a Windows host with a source EMC Storage system. The host DSM must be updated to communicate with the destination HP 3PAR StoreServ Storage system, and the host must be shut down briefly. Host I/O is interrupted only during the time it takes to reconfigure the host.
Required Information
Source storage system:
•WWN of the source EMC Storage system from which LUNs are being migrated.
•A list of one or more volume name(s) that are being migrated. All volumes must be in same storage group or different storage groups with identical LUN membership.
OR
Name of host associated with volumes to be migrated. The host and volumes must be in a supported storage group configuration on the source EMC Storage system. See “Migrations Supported by HP 3PAR Online Import Utility for EMC Storage” (page 24) for details.
Destination storage system:
•Provisioning type for the volumes being created on the destination storage system (thin or full). NOTE: TDVVs are not supported as a destination for online import.
•The name of the CPG on the destination storage system where the volumes are being migrated to.
