7 Performing MDM Using a Linux Host
The MDM type can be used when migrating a Linux host with a source EMC Storage system. The host must be shut down briefly during MDM. Host I/O is interrupted only during the time that the host is shut down.
If you are performing online migration, see “Performing Online Data Migration Using Linux” (page 40).
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 names that are being migrated. All volumes must be in the same storage group or different storage groups with identical LUN membership.
OR
Name of the host associated with volumes to be migrated. 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.
