◦One initiator group “parent” is added and associated to the HP 3PAR peer port initiator groups. The naming convention is:
OIU_<migrationID>_IG
◦One port group is added, containing the required ports based on the original masking views. The naming convention is:
OIU_<migrationID>_PG
After all of these groups have been created and populated, a migration masking view is added and associated to the migration storage group, initiator group, and port group. The naming convention is:
OIU_<migrationID>_MV
NOTE: For VMAX, these groups remain on the VMAX system after migration is completed; they are not cleaned up.
•Hosts are created on the destination storage system.
•Volumes are admitted to the destination storage system but are not exported to the host.
•The createmigration command performs the following checks before creating the migration:
◦No existing migration task for specified source storage system:
–Only one migration at a time can be provisioned for a given source EMC Storage system.
◦The source storage system group configuration is valid.
–The volumes or host specified in the createmigration command are mapped to a storage group on the associated source EMC Storage system. All LUNs and all hosts in the mapped storage group will be migrated even if only a subset are entered in the createmigration command. To determine whether your configuration is valid, see “Migrations Supported by HP 3PAR Online Import Utility for EMC Storage” (page 24).
