User's Guide

◦ 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).
◦ EMC SMI-S Provider version.
◦ Source storage system model number.
NOTE: See the HP SPOCK website for the latest supported versions:
HP SPOCK (http://www.hp.com/storage/spock)
◦ LUN migration eligibility:
Protocol must be Fibre Channel.–
– Replication LUN cannot be migrated.
